Brian spent 28 dollars at the mall that was 4 times as much as kim spent how much money did kim spend

7

Step-by-step explanation:

28/4=7

7*4=28

$7

Step-by-step explanation:

"4 times" means multiply by 4.

The opposite operation to multiplication is division.

Divide $28 by 4.

$28/4 = $7

Kim spent $7.

okay wait before i answer, is this for your points on a graph?

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
