Answer: 70 mph
Step-by-step explanation:
Twice a increased by the cube of a equals b :
2a + a^3 = b
Answer:
10
Step-by-step explanation:
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
The answer is to what is 5/2 divided by 1/4 is 10
