Suppose you want to purchase a house. Your take-home pay is $3900 per month, and you wish to stay within the recommended guidelines for mortgage amounts by
only spending 1/4 of your take-home pay on a house payment. You have $17,800 saved for a down payment and you can get an APR from your bank of 5.25%, compounded monthly. What is the total cost of a house you could afford with a 15-year mortgage? Round your answer to the nearest cent if necessary.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

the answer is 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
