You are going to mow your neighbor's lawn for some extra money. Below is a scale drawing of their lawn, where each square represents 5 feet. What is the perimeter of the real lawn (not the scale drawing)?

Your neighbor will either pay you $40 as a flat rate, or they will give you $0.03 for each sq. foot (3 cents per square foot). Which would make you the most money? Show all your work on a paper and insert the image with the final answer here:

for b its (t) and c its (d)

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

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
