Not entirely sure but it may be 35 mpg.
Answer:
Since we have BC ║ DE, we know that:
AB/AD = BC/DE
12/(12 + 4) = BC/12
12/16 = BC/12
BC = (12 · 12)/16 = 9 (in)
Applying the pythagorean, we have:
AB² + BC² = AC²
12² + 9² = AC²
225 = AC²
AC = √225 = 15 (in)
Using the information about the parallel lines again, we have:
AC/CE = AB/BD
15/CE = 12/4
CE = (15 · 4)/12 = 5 (in)
So the answer is B
Divide the number of revolutions by the number of seconds.
(6 2/5) / (2 2/3) =
Rewrite each mixed numeral as a fraction.
= (32/5) / (8/3)
= 32/5 * 3/8
= 96/40
= 12/5
= 2 2/5
Answer: 2 2/5 revolutions per second
The answer is x=1

Answer:
A
Step-by-step explanation:
Given
6x + 2 - 8x + 7 = 4x + 1 ← simplify left side
9 - 2x = 4x + 1 ( subtract 4x from both sides )
9 - 6x = 1 ( subtract 9 from both sides )
- 6x = - 8 ( divide both sides by - 6 )
x =
