To solve this problem we need to determine if 85% is 34, then what is 100%

The easiest way to do this is to set up a proportion 

Being \frac{34}{85}       \frac{x}{100}

To figure out the "rule" between 85 and 100, we divide 100 by 85.

100/85 = 20/17

To check our rule we can do 85 x 20/17 which = 100 

Now to solve the problem so, 34 x 20/17 = 40

Our answer would be 40 :)

If Marissa got an 85% on her math quiz and she got 34 questions right, there would be a total of 40 questions on the test.

I hope this helps!

Solving a System of Linear Equations - Applications - Item 92238
Viktor [21]

Answer:

$132

Step-by-step explanation:

1) In this system of eqn x represents the price of washing cars and y represents the price of washing SUVs

2) From the given eqn,

y = (84 - 4x)/2

and

y = (126 - 3x)/5

equating both the equation,

(84 - 4x)/2 = (126 - 3x)/5

=> 210 - 10x = 126 - 3x

=> 7x = 84

=> x = 12

=> y = (84 - 48)/2 = 18

Hence the co-ordinate of intersection will be (12,18)

3) The total cost of 1 car and 1 suv = x + y = 12 + 18 = $ 30

4) The total earning of hour 3

= 5x + 4y

= 5.12 + 4.18

= 60 + 72

= $ 132

The perimeter of a rectangle is 40 m. The length is 4 m more than three times the width. Find the length and the width of the re
galina1969 [7]

Answer:

Width = 4 m, Length = 16 m

Step-by-step explanation:

Perimeter = 40

Width = x

Length = 3x + 4

x + x + 3x + 3x + 4 + 4 = 8x + 8

40 - 8 = 32

32/8 = x

x = 4

Width = 4

Length = 16
