A cash box of $1 and $5 bills is worth $45. The number of $1 bills is three more than the number of $5 bills. How many of each bill does it contain?

$5: 7

$1: 10

Step-by-step explanation:

We can write the equation as such.

1. 5x + (x + 3) = 45

2. 6x = 42

3. x = 7

The number of $5 bills is 7, now we can use the x + 3 to solve the amount of $1 bills.

1. x + 3 = ?

2. 7 + 3 = 10

There are 10 $1 bills.

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)
