9. Use the Distributive Property to solve the
equation 28-(3x+4)= 2(x+6) +x.
WITH SOLUTION please
Answers
Answer:
x=2
Step-by-step explanation:
T= 2
28 - (3æ+4) = 2(r + 6) + *
We need to use the distributive property for the
right side.
28 - 3z -4 = 2a + 12 + z
28 -3z -4 = (2) (æ) + (2)(6) + æ)
From here we need to subtract 3æ from both side.
-3æ + 24 -3 = 3æ + 12 – 3¢
3æ + 24 = 3z + 12
6z + 24 = 12
Transfer +24 on the right side. (P.S. don't forget to
change the sign)
62 = 12 - 24
6 = - 12
Finally, divide both sides by -6
6x/-6 = -13/-6

Solve 7w-9=13 - 4w.
W =
Answers
Answer:
w=2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7w−9=13−4w
7w+−9=13+−4w
7w−9=−4w+13
Step 2: Add 4w to both sides.
7w−9+4w=−4w+13+4w
11w−9=13
Step 3: Add 9 to both sides.
11w−9+9=13+9
11w=22
Step 4: Divide both sides by 11.
11w/11=22/11

Julia works for a company selling light bulbs. She sells fluorescent light bulbs for $5 a piece and incandescent light bulbs for $2. To meet her quota, she needs to sell over 100 light bulbs and make at least $350.If the solution region is the amount of light bulbs Julia needs to sell to meet her quota, which graph's shaded area represents the solution region?
Answers
Given:
Julia works for a company selling light bulbs. She sells fluorescent light bulbs for $5 a piece and incandescent light bulbs for $2.
Let the number of the fluorescent light bulbs = y
And the number of the incandescent light bulbs = x
To meet her quota, she needs to sell over 100 light bulbs and make at least $350.
So, we can write the following system of inequalities:
[tex]\begin{gathered} x+y>100 \\ 2x+5y\ge350 \end{gathered}[/tex]Now, we will graph the system of the inequalities to find the area of the solution
The graph will be as follows:
So, the answer will be the graph that is on the upper right-side.

Answers
hello
determine the amount each of them have, let's write an equation to represent thier total amount
let x represent the amount Jason have
let y represent the amount Jeff has
now, we know that Jason has 3 more than 4 times the amount Jeff has
x = 4y + 3 .... equation 1
x + y = 72 .... equation 2
from equation 2,
make x the subject of formula
[tex]\begin{gathered} x+y=72 \\ x=72-y \end{gathered}[/tex]x = 72 - y .....equation 3
put equation 3 into equation 1
x = 4y + 3
72 - y = 4y + 3
solve for y
[tex]\begin{gathered} 72-y=4y+3 \\ \text{collect like terms} \\ 4y+y=72-3 \\ 5y=69 \\ y=\frac{69}{5} \\ y=13.8 \end{gathered}[/tex]we know y = 13.8
we can simply substitute the value into equation 2 and solve for x
[tex]\begin{gathered} x+y=72 \\ y=13.8 \\ x+13.8=72 \\ x=72-13.8 \\ x=58.2 \end{gathered}[/tex]therefore, Jason has $58.2 and Jeff has $13.8

The number of guests that can be served is 12
How to determine the number of guests?From the question, we have the following parameters that can be used in our computation:
Meat served: 4 lbs chicken with a bone
Pounds of meat available: 48 lbs.
The number of guests needed is calculated using the following equation
Number of guests = Pounds of meat available/Meat served
Substitute the known values in the above equation, so, we have the following representation
Number of guests = 48/4
Evaluate the quotient
Number of guests = 12
Hence, 12 guests can be served with the available meat

Answers
The equation is y+9=(1/5)(x-2).
What is a slope form?It is used to find the equation of the straight line which is inclined at a given angle to the x-axis and passes through a given point. The three major forms of linear equations are point-slope form, standard form, and slope-intercept form. The equation of the slope form is y-y₁ = m(x - x₁)
The formula for the point-slope is,
y-y₁ = m(x - x₁)
y₁ is the y-coordinate of the point in the line, x₁ is the x-coordinate of the point in the line and m is the slope.
y₁ = -9
m = 1/5
x₁ = 2
Substituting the above values in the above equation, we get
y-(-9) = (1/5)(x-2)
By simplifying the above equation, we get
y+9 = (1/5)(x-2)
Therefore, the equation is y + 9 = (1/5)(x-2).

A real estate licensee leased a building for 10 years at an annual rent of$48,000. she will receive a commission of 7.5 % for the first 5 years, 5% for the next there years and 3.5% for the final two years. what will her income be from this commission over the life of the lease?
Answers
We have the lease of a building is for 10 years with an annual rent of $48 000.
We first determine the 7.5% for the first 5 years, for that we add the cost of the rent for 5 years, that is:
[tex]5(48000)=240000[/tex]In 5 years the rent will be of $240 000, now we find the 7.5%:
[tex]c_5=\frac{240000\cdot7.5}{100}\Rightarrow c_5=18000[/tex]Her commision for the first 5 years is going to be of $18 000.
Now we determine the 5% for the next 3 years, for this we determine the rent for 3 years:
[tex]3(48000)=144000[/tex]The rent for 3 years adds $144 000, now we determine the 5%:
[tex]c_3=\frac{144000\cdot5}{100}\Rightarrow c_3=7200[/tex]From this we have that the commission for the next 3 years will be of $7200.
And finally, we determine the rent for the two remaining years:
[tex]2(48000)=96000[/tex]We have that the last two years the rent will be of $96000, now we determine the 3.5% of her commission during that time:
[tex]c_2=\frac{96000\cdot3.5}{100}\Rightarrow c_2=3360[/tex]From this we have her commission for the last two years will be of $3360.
Finally we add all of the values of the commissions she will get:
[tex]c_t=18000+7200+3360\Rightarrow c_t=28560[/tex]From this we have that the total commision money she will be getting during those 10 years will be $28 560.

Where can I calculate the shaded area of this diagram?
Answers
We are asked to find the area of the shaded region.
Notice that the overall figure is a rectangle and the missing area is a triangle.
The area of the rectangle is given by
[tex]A_{\text{rect}}=w\cdot l[/tex]Where w is the width and l is the length of the rectangle.
width = 7 m
length = 16 m
[tex]A_{\text{rect}}=w\cdot l=7\cdot16=112\; \; m^2[/tex]So, the area of the rectangle is 112 m²
The area of the triangle is given by
[tex]A_{\text{tri}}=\frac{1}{2}\cdot b\cdot h[/tex]Where b is the base and h is the height of the triangle.
base = 7 m
height = 8 m
[tex]A_{\text{tri}}=\frac{1}{2}\cdot b\cdot h=\frac{1}{2}\cdot7\cdot8=28\; \; m^2[/tex]So, the area of the triangle is 28 m²
The area of the shaded region can be found by subtracting the area of the triangle from the area of the rectangle.
[tex]\begin{gathered} A=A_{\text{rect}}-A_{\text{tri}} \\ A=112-28 \\ A=84\; \; m^2 \end{gathered}[/tex]Therefore, the area of the shaded region is 84 m²
a stationary shop had an equal number of pens and notepads at first. after selling 1250 pens and 380 notepads, there were 4 times as many notepads as pens left. how many pens did the stationary shop have at first
Answers
The stationary shop had 90 pens with them initially.
Let,
The number of pens initially at the stationary shop=x
The number of pens and the number of notepads are said to be equal. Therefore, The number of notepads initially at the stationary shop=x
After selling,
The number of pens = x-1250
The number of notepads = x-380
The number of pens was four times the number of the number of notepads. Modelling the linear equation for the situation:
x-1250=4(x-380)
x-1250=4x-1520
x=4x-270

The value of the variable x: 40
Angles of the polygon are :
3x = 120(2x + 10) = 90(2x + 5) = 85(2x - 15) = 65What is Polygon?An Indian blockchain scalability platform is called Polygon. It addresses Ethereum's problems with excessive costs, a subpar user experience, and a meager number of transactions per second. Creating a framework for Proof of Stake transactions is one approach taken to overcome these problems.Calculate the measure of angles as follows:
3x(2x + 10)(2x + 5)And
(2x - 15)Since we have,
Sum of angle measure = 360°
Thus: 3x + (2x + 5) + (2x + 10) + (2x - 15) = 360Opening the brackets:
3x + 2x + 5 + 2x + 10 + 2x - 15 = 360Adding the like terms:
9x + 15 - 15 = 3609x = 360x = 360/9x = 40Hence, The measure of the variable is 40.
And the angle measures are:
3 x 40 = 120°(2(40) + 5) = 80 + 5 = 85°(2(40)+ 10) = 80 + 10 = 90°(2(40) - 15) = 80 - 15 = 65°Therefore, the value of the variable x: 40
