Answer:
4x + 1
Step-by-step explanation:
If April adds her expressions together correctly, she'll get 14x + 4; Evan will get 18x + 5.
Evan's is the greater sum. So, to answer this question we subtract April's sum from Evan's:
18x + 5
-(14x + 4)
--------------
4x + 1
Evan's sum is 4x + 1 greater than April's sum.
Answer:
20 band posters
Step-by-step explanation:
Set up a proportion where x is the number of band posters she should sell:
=
Cross multiply and solve for x:
2400 = 120x
20 = x
So, she should sell 20 band posters.
If she sells 20 band posters and 24 movie posters, the ratio will be 96:80, which is the same as 120:100. Simplified, both ratios are 1.2:1
We will see that Bruce's tiles cover more area, and Bruce's equation is:
y = (1/4 ft^2)*x
<h3>
Finding the proportional relation.</h3>
A general proportional relation is written as:
y = k*x
Where k is the constant of proportionality.
To know how much area covers each tile of Felicia, we need to use the data in the table to get the value of k.
By taking the quotient between the difference of two y-values and two x-values on the table, we can get the constant, for example, if we use the first two we get:
That constant means that we need 9 tiles to cover 1 ft^2 this is equivalent to saying that a single tile covers (1/9) of a square feet.
Then Felicia's equation is:
Y = (1/9 ft^2)*x
Similarly, Bruce's equation will be:
y = (1/4 ft^2)*x
Because we know that each of Bruce's tiles covers (1/4) ft^2
From this, we can conclude that Bruce's tiles cover more area.

Im assuming that you are wanting to find x. Follow these steps to get the answer
1. You need to write out the equation
2. You need to get to get the 3 away from that side with the X. To do that, you have to do the opposite of division, which is multiply. You will multiply the 3 by 3 which cancels it out.
3. Since you canceled out the 3 on the one side, you have to do it to the other.
4. Multiply 27 by 3. Which gives you 81.
5. You are left with -x=81. You’ve got to get the x all by itself, so you need to get rid of the negative sign. In order to do that, you need to divide the -x by -1. The reason for that is because you’re taking the negative part of x away, which will leave you with x.
6. Since you divided -1 out of -x, you will need to do that to the other side.
7. That leaves you with x = - 81. Which is your answer.
