<h3>
Answer: 20 lawns</h3>
Work Shown:
8 lawns = 2 hours
4 lawns = 1 hour (divide both sides by 2)
20 lawns = 5 hours (multiply both sides by 5)
Answer:
A,C,F
Step-by-step explanation:
Answer:
I think it is a) exponential
Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
