Answer:
36miles
Step-by-step explanation:
Given parameters:
Rate = 12mph
Time = 3hr
Unknown:
Distance = ?
Solution:
The given rate amount is the speed. Speed is the distance divided by the time.
It is mathematically expressed as:
Speed = [tex]\frac{distance}{time}[/tex]
Distance = Speed x time
Distance = 12 x 3 = 36miles
h(t) = -16t2 + 160t + 384 rewrite in factored form

Answer:
Step CStep-by-step explanation:
Incorrect Step is C:
-x = y + 3 incorrectx = -y + 3 correctWhat is the value of x?
Answer:
x = 16
Step-by-step explanation:
(x+2) + (7x+2) + (3x) = 180
Add like terms
7x + x + 3x = 11x
2 + 2 = 4
11x + 4 = 180
Subtract 4
11x + 4 = 180
11x = 176
Divide by 11
11x = 176
x = 16
