3/4(x-2)+1/3(2x+5)=4
Answer:
X=86/17
Step-by-step explanation:
Answer:
x=46/17
Step-by-step explanation:
Let's solve your equation step-by-step.
3/ 4 (x−2)+ 1/ 3 (2x+5)=4
Step 1: Simplify both sides of the equation.
3/ 4 (x−2)+ 1/ 3 (2x+5)=4
( 3/ 4 )(x)+( 3/ 4 )(−2)+( 1/ 3 )(2x)+( 1/ 3 )(5)=4 (Distribute)
3/ 4x+ −3/ 2 + 2/ 3 x+ 5/ 3 =4
( 3/ 4 x+ 2/ 3 x)+( −3/ 2 + 5/ 3 )=4 (Combine Like Terms)
17/ 12 x+ 1/ 6 =4
17/ 12 x+ 1/ 6 =4
Step 2: Subtract 1/6 from both sides.
17/ 12 x+ 1/ 6 − 1/ 6 =4− 1/ 6
17/ 12 x= 23/ 6
Step 3: Multiply both sides by 12/17.
( 12/ 17 )*( 17/ 12 x)=( 12/ 17 )*( 23/ 6 )
x= 46/ 17

1. The Agent Earned $6,303
First, the real estate agency will earned 5.5%
5.5/100 * $382,000 = $21,010
Then, the agent earns 30% of $21,010
30/100 * $21,010 = $6,303
2. Basically, we're setting up an equation where Option A and Option B are the same amount.
For option A, you are making 23 dollars each hours, for 40 hours. (40*23)
For option B, you are making 4% of your sales. We're looking for how much she sells, so we can write that as x. (.04x)
Set the 2 options as equal and solve for x. so x is 920(.04x
sorry if wrong it was really hard
3. If 90% are women, 10% are men.
If x is the total amount of people.
.1x = 320
Solve x from here.

Answer:
x = 11.74739484
Step-by-step explanation:
To solve this problem, you can use trig functions. We are given an angle and the side next to it, and we are looking for the side opposite it. The perfect trig function to use for this would be tangent:
tan(θ) = opposite / adjacent
We can substitute the values we already have:
tan(40) = x / 14
x = 14 * tan(40)
We can evaluate this using a calculator and get:
x = 11.74739484

Answer:
D, B
Step-by-step explanation:
Price per pound is found by dividing dollars by pounds.
Store A: $9/(3 lb) = $3.00 /lb
Store B: $9.75/(3 lb) = $3.25 /lb
Store C: $12.40/(4 lb) = $3.10 /lb
Store D: $14.50/(5 lb) = $2.90 /lb
Part A: The lowest price per pound is $2.90 per pound at store D.
Part B: The highest price per pound is $3.25 per pound at store B.
In a circle of radius 10 cm, a sector has an area of 40 (pi) sq. cm. What is the degree measure of the arc of the sector?
72
144
180°
Answer:
144°
Step-by-step explanation:
First, find the area of the circle, with the formula A = [tex]\pi[/tex]r²
Plug in 10 as the radius, and solve
A = [tex]\pi[/tex]r²
A = [tex]\pi[/tex](10²)
A = 100[tex]\pi[/tex]
Using this, create a proportion that relates the area of the sector to the degree measure of the arc.
Let x represent the degree measure of the arc of the sector:
[tex]\frac{40\pi }{100\pi }[/tex] = [tex]\frac{x}{360}[/tex]
Cross multiply and solve for x:
100[tex]\pi[/tex]x = 14400[tex]\pi[/tex]
x = 144
So, the degree measure of the sector arc is 144°
Answer:
Solution :-We know that
Area = πr²
Area = 3.14 × (10)²
Area = 314/100 × 100
Area = 314 cm²
Now
40π/314 = x/360
40 × 3.14/314 = x/360
125.6/314 = x/360
0.4 = x/360
0.4 × 360 = x
144 = x

what is the first step to solving this equation?
-5+6=4
a. subtract 6 from both sides
b. multiply both sides by 5
c. divide both sides by -5
d. add 6 to both sides
Answer:
a. subtract 6 from both sides
Step-by-step explanation:
Given the algebraic expression;
-5c + 6 = 4
First of all, we would subtract 6 from both sides. This would eliminate the "6" on the left side.
-6 - 5c + 6 = 4 - 6
-5c = -2
5c = 2
Dividing both sides by 5, we have;
c = 2/5
Suppose you have a litter of mice which consists of 5 males and 3 females. If you randomly grab two of them without replacement.
1. what is the probability that they are both male?
2. what is the probability that you get at least one female
3. what is the probability that one is male and one is female
Problem 1
Answer: 5/14-----------------------
Explanation:
We have 5 males and 3 females, so there are 5+3 = 8 mice total. The probability of selecting a male is 5/8. After that male is chosen, there are 5-1 = 4 of them left out of 8-1 = 7 total. This subtraction happens because the first mouse selected is not replaced. The probability of picking another male is 4/7.
Multiplying these fractions leads to the answer
(5/8)*(4/7) = (5*4)/(8*7) = 20/56 = 5/14
Note: to reduce 20/56 into 5/14, you divide both parts by the GCF 4.
====================================================
Problem 2
Answer: 9/14-----------------------
Explanation:
The events "selecting two males" and "selecting at least one female" are complementary events. One or the other, but not both, must happen.
If we let
A = event of selecting two malesB = event of selecting at least one female (ie one or more females)then we can say
P(A) + P(B) = 1
P(B) = 1 - P(A)
P(B) = 1 - (5/14)
P(B) = (14/14) - (5/14)
P(B) = (14-5)/14
P(B) = 9/14
Note how P(A) = 5/14 is the result from problem 1.
====================================================
Problem 3
Answer: 15/28-----------------------
Explanation:
The probability of selecting a male is 5/8. After the male is chosen, there are 8-1 = 7 mice left. The probability the second mouse is female is 3/7 since there are 3 female mice out of 7 left total.
We get this result after multiplying the values: (5/8)*(3/7) = 15/56
Now consider that the first mouse is female. The probability of this is 3/8. The probability that the second mouse is male is 5/7.
The fractions multiply to (3/8)*(5/7) = 15/56. We get the same result as before due to the numerators swapping places, but not much else happens. So we have a sort of symmetry going on here.
The last step is to add the two results we got:
(15/56)+(15/56) = (15+15)/56 = 30/56 = 15/28
Or you could compute it like this
2*(15/56) = (2*15)/56 = 30/56 = 15/28
The '2' is to signify there are two ways to select exactly one male and exactly one female, where the order doesn't matter.
--------------------------
Here's another way we can get the answer.
The probability we get both males is 5/14 found back in problem 1.
The probability we get both females will follow the same idea as problem 1, and we would compute (3/8)*(2/7) = 6/56 = 3/28
Add those fractions: (5/14) + (3/28) = (10/28) + (3/28) = 13/28
Now consider the events
C = event of selecting two mice of the same gender (both are male OR both are female; pick 1 scenario only)D = event of selecting two mice of different genders (the first is male, the other is female, or vice versa)Events C and D are complementary events.
We calculated that P(C) = 13/28, which means
P(D) = 1 - P(C)
P(D) = 1 - (13/28)
P(D) = (28/28) - (13/28)
P(D) = (28-13)/28
P(D) = 15/28
Johnny was buying pizza rolls. One sausage pizza roll cost 1.54 and he also bought pepperoni flavored rolls. If he buys 6 sausage rolls and 10 pepperoni rolls and he spends $22.54 in total. How much does a pepperoni roll cost?
Answer:
$1.33
Step-by-step explanation:
multiply 6 by 1.54 to see how much he spent on sausage rolls
subtract that from the total ($22.54)
divide by 10 to see how much each pepperoni roll costs
Answer:
$1.33
Step-by-step explanation:
1.54x6=9.24
22.54-9.24=13.30
13.30/10=1.33
The Home Depot has two special lawnmowers for sale this year. The electric mower costs $300 each, and the gas-powered mower costs $450 each. The store has room for 25 total mowers, and the store has to order at least $6000 worth of mowers to start the sale.
Answer:
300a + 450b ≤ 6000
Step-by-step explanation:
Given:
Cost of electric mower = $300
Cost of gas mower = $450
Total number of mower = 25
Cost of total mower is at least = $6,000
Find:
Number of each mower equation
Computation:
Number of electric mower = a
Number of gas mower = b

f(x)=-x+3
let y=-x+3
interchanging role of x & y
x=-y+3
y=3-x
f-¹(x)=-x+3
equal to g(x)=-x+3
Given function are inverse of each other.
Answer:
Step-by-step explanation:
Call h(x) = y (It's easier to see).
y = -x - 1
The first step is always to interchange x and y
y = -x - 1
-x = y - 1
Solve for y
-x + 1 = y
If I understand the question, these two (f(x) and h(x)) are not inverses.
10 is a bit tricky. An inverse can invert into itself: This is called an involution. But if they are differently labeled, I'm not sure. I don't think that this is exactly what is men by an involution. Something like y = x would be. But you have 2 different inverses. I'm not sure that this qualifies.
y = x + 3
g = x + 3
x = y + 3
x - 3 = y

Question 13 I don’t know how to do it
Answer:
y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)
Step-by-step explanation:
The roots from the graph are
x = - 6 , then factor is (x + 6)
x = - 2 , then factor is (x + 2)
x = 1 ( multiplicity 2 ) , then factor is (x - 1)² then
y = a(x - 1)²(x + 2)(x + 6) ← a is a multiplier
To find a substitute any point on the graph into the equation
Using (0, - 3 ), then
- 3 = a(- 1)²(2)(6) = 12a ( divide both sides by 12 )
- [tex]\frac{1}{4}[/tex] = a
Then
y = - [tex]\frac{1}{4}[/tex] (x - 1)²(x + 2)(x + 6)
