17 = 5-x what's the answer
Answer:
X = - 12.
Step-by-step explanation:
17 = 5 - x
17 = 5 + - x
17 = - x + 5
Then, flip the equation.
-x + 5 = 17
Then subtract 5 from both of the sides.
-x + 5 - 5 = 17 - 5
-x = 12
Then divide
-x/ -1 = 12/1
x = - 12.
Hope this helps!

What is the sum of the geometric sequence 1, -6, 36, ... If there are 6 terms? (1 point)
Answer:
-6665
Step-by-step explanation:
The given GP is :
1, -6, 36, ...
Number of terms = 6
The sum of n terms of a GP is given by :
[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]
Here,
a = 1, n = 6, r = 36/-6 = -6
So,
[tex]S_6=\dfrac{1((-6)^6-1)}{(-6)-1}\\\\=-6665[/tex]
So, the sum of th GP is -6665.

The phone case you want to buy is marked down 30% and you have a 25% off coupon. You pay 42 dollars. Can this equatio be used to find the original cost of the phone case?If so what is the original price of the item. Explain.
Answer:
Step-by-step explanation:
Original price = x
75% of 70% of x = $42
0.75*0.70x =$42
x = $42/(0.75*0.70) =$42/0.525 = $80
12. ALGEBRA Sherri Cole found that the 12-ounce can of frozen orange juice
sells for $0.16 less than the 16-ounce can, which is $0.68 less than the
24-ounce can. If the unit price of the 24-ounce can is $0.005 less than the
unit price of the 12-ounce can, which of the three is the best buy based
on the lowest unit price?
Answer:
96 = x
Step-by-step explanation:
I'm going to use cents instead of dollars because I find decimals and fractions to be cumbersome. I assume you meant $.005 instead of 4.005.
Let x denote the price (in cents) of the 12-ounce can. Then the price of the 16-ounce can is (x + 16) cents, and the price of the 24-ounce can is ((x + 16) + 68), or (x + 84) cents.
The unit price (cents per ounce) of the 12-oz can is x/12
The unit price of the 16-oz can is (x + 16)/16
The unit price of the 24-oz can is (x + 84)/24
You are told that, in terms of x,
(x + 84)/24 = x/12 - 0.5
Multiply both sides by 24:
x + 84 = 2x - 12
Solve for x:
96 = x
So the unit prices (in cents per ounce) are:
12 oz: 96/12 = 8 cents/oz
16 oz: 112/16 = 7 cents/oz
24 oz: 180/24 = 7.5 cents/oz
So the 16 ounce can is the best buy based on lowest unit price.
In this exercise we have to use the knowledge of finance to calculate the best price to be offered, in this way:
[tex]12 oz: 96/12 = 8 cents/oz\\16 oz: 112/16 = 7 cents/oz\\24 oz: 180/24 = 7.5 cents/oz[/tex]
Some values should be simplified as they were informed in the statement:
The unit price (cents per ounce) of the 12-oz can is x/12The unit price of the 16-oz can is (x + 16)/16The unit price of the 24-oz can is (x + 84)/24So putting together an equation with these values and terms informed we find that:
[tex](X + 84)/24 = X/12 - 0.5\\X + 84 = 2X - 12\\X=96[/tex]
So with the value of X found it is only necessary to use the previous equations and replace this value.

The rectangle below has an areas of x^2+8x+15 square metres and a width of x+3 meters what expression represents the length of the rectangle
Answer: x+5 or ((x^2+8x+15)/(x+3))
Step-by-step explanation: First let's assign our variables.
x^2+8x+15 = Area
X+3 = Width
? = Length
If the equation of a=lw, then we can substitute in our variables.
a=lw
x^2+8x+15= L (x+3)
Now we must isolate L.
Divide both sides of the equation by 'x+3'
x^2+8x+15= L (x+3)
x+3 x+3
x+5= L
x−8≥4
x=?

Onur is participating in a walkathon fundraiser. Two donors promised to donate money based on the total distance he walks. The money, A, in dollars, that he receives from the first donor given that he walks d kilometers is given by the formula A(d)=10d. The money, B, in dollars, that he receives from the second donor given that he walks d kilometers is given by the formula B(d)=2d+d^2.
Let T be the total money that Onur raises from those donors by walking d kilometers in the walkathon.
Write a formula for T(d), in terms of A(d) and B(d).
T(d)= ?
Write a formula for T(d), terms of d.
T(d)=?
Answer:
1. T(d) = A(d) + B(d)
2. T(d) = 12d + d²
Step-by-step explanation:
From the question given above, the following data were obtained:
A(d) = 10d
B(d) = 2d + d²
1. Determination of the formula of T(d) in terms of A(d) and B(d).
T(d) is the total money obtained. Thus,
T(d) = A(d) + B(d)
2. Determination of the formula of T(d) in terms of d.
A(d) = 10d
B(d) = 2d + d²
T(d) =?
T(d) = A(d) + B(d)
T(d) = 10d + 2d + d²
T(d) = 12d + d²

The top of a building is a cone 10 meters tall with a radius of 4 meters at the base. Round to the nearest hundredth.
Answer:
V = 167.55 m³
Step-by-step explanation:
Given that,
The height of a cone, h = 10 m
Radius of the cone, r = 4 m
It can be assumed to find the volume of the cone. Th formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2 h\\\\V=\dfrac{1}{3}\pi \times (4)^2\times 10\\\\V=167.55\ m^3[/tex]
So, the required volume is 167.55 m³.
What is the equation of the line that passes through the point (4, -2) and has a
slope of -22
Answer: the answer is y=-22x+86
here is why:
the slope is -22 which is the m --> y=mx+b the point is (4,-2) the x=4 and y= =2
If we set up the equation:
-2= -22(4)+86
-2= -88+86
-2= -2
