Answer:
$2.35
Step-by-step explanation:
Nickels are worth 5 cents each and quarters are worth 25 cents.
7 nickels = 7 * 5 cents = 35 cents
8 quarters = 8 * 25 cents = 200 cents
Total = 200 + 35 = 235 cents
There are 100 cents per dollar, so we can find the dollar value by:
235/100 = $2.35
A linear equation in two variables describes a relationship in which the value of one of the variables depends on the value of the other variable. In a linear equation in x and y, x is called x is the independent variable and y depends on it. We call y the dependent variable.

Given:
![$\frac{7}{r}+2^{3}+\frac{s}{3}+11](https://tex.z-dn.net/?f=%24%5Cfrac%7B7%7D%7Br%7D%2B2%5E%7B3%7D%2B%5Cfrac%7Bs%7D%7B3%7D%2B11)
To find:
Which statement are true?
Solution:
Option A: The entire expression is a sum.
It is true because it performed addition operation.
Option B: The coefficient of s is 3.
![$\frac{7}{r}+2^{3}+\frac{s}{3}+11=\frac{7}{r}+2^{3}+\frac{1}{3}s+11](https://tex.z-dn.net/?f=%24%5Cfrac%7B7%7D%7Br%7D%2B2%5E%7B3%7D%2B%5Cfrac%7Bs%7D%7B3%7D%2B11%3D%5Cfrac%7B7%7D%7Br%7D%2B2%5E%7B3%7D%2B%5Cfrac%7B1%7D%7B3%7Ds%2B11)
It is not true because the coefficient of s is
.
Option C: The term
is a quotient.
If we divide 7 by r, we obtain a quotient.
So it is true.
Option D: The term
has a variable.
It is not true because it does not contain any variable.
Therefore the entire expression is a sum and the term
is a quotient are true statement.
