Answer:

12 1/7 cars

Step-by-step explanation:

Let the number of cars she'd wash to earn $63 in spending money be A.

Given she saves $22 of her weekly earnings and wants to have at least $63 for spending money.

That means she’d have to make $63 + $22 = $85

The expression is thus

$85 = A x $7

Where A is the number of cars and $7 is the amount she earns for washing one car and $85 is the total amount she has to make .

Therefore,

85 = A x 7

Divide both sides by 7

85/7 = A x 7/7

12 1/7 = A

A = 12 1/7 cars

She must wash 12 1/7 cars to have at least $63 spending money and also have her weekly Savings of $22

Answer: 12 1/7 cars

Step-by-step explanation:

Let the number of cars she'd wash to earn $63 in spending money be A.

Given she saves $22 of her weekly earnings and wants to have at least $63 for spending money.

That means she’d have to make $63 + $22 = $85

The expression is thus

$85 = A x $7

Where A is the number of cars and $7 is the amount she earns for washing one car and $85 is the total amount she has to make .

Therefore,

85 = A x 7

Divide both sides by 7

85/7 = A x 7/7

12 1/7 = A

A = 12 1/7 cars

She must wash 12 1/7 cars to have at least $63 spending money and also have her weekly Savings of $22.

ollegr [7]

Answer:

y =  - 4x - 42

Step-by-step explanation:

The equation of the line that is parallel to the line we are trying to find is

- 3y + 4x = 9 \\ or \\  - 3y =  - 4x + 9 \:(standard form) \\ \\therefore \: the \: slope \: of \: the \: line \\  \: is \:  - 4

We can recall that when two lines are parallel it means that they have the same slope. Therefore the slope of the line we are trying to find is also -4. We now know that:

y = 6 \:  \:  \: x =  - 12 \:  \:  \: slope =  - 4

Therefore the equation of the line is:

y = mx + c \\  6= ( - 4)( - 12) + c \\ 6 = 48 + c \\ 6 - 48 = c \\  - 42 = c

y = mx + c \\ y =  - 4x - 42
