x - 2 = 7 + x/4
4x - 8 = 28 + x
3x = 36
x = 12
if the quotient of -20 and 4 is decreased by 3
So let's call the number we are looking for x. x-4 is the number decreased by 4 quotient of the number and 5 is x/5 so x-4=8+ x/5 we have 5x-20=40+x and 4x=60 so x=15 Let's try it? 15-4=11 8+15/5=11
x-4=8+x/5 5(x-4)=5(8+x/5) 5x-20=8+x 4x=28 x=7

r/2-8
A quotient is the number obtained when one number is divide by another. 11 decreased by 10 is 1. The only number that can be paired with -9 to obtain a quotient of 1 is -9.

It has decreased.
Increased
If a fraction's denominator is increased, the number gets smaller. If a fraction's denominator is decreased, the number gets bigger.
r/2-8
. This is same as half of r.
To express "a number r decreased by the quotient of a number r and two," you can write the mathematical expression as ( r - \frac{r}{2} ). Here, ( \frac{r}{2} ) represents the quotient of ( r ) divided by 2, and subtracting this from ( r ) captures the idea of decreasing ( r ) by that value.
