Given equation is 3(-a-3)-2(3a+3)=-78
we can start by distributing numbers which are outside parenthesis
3(-a-3)-2(3a+3)=-78
-3a-9-6a-6=-78
combine like terms
-9a-15=-78
-9a=-78+15
-9a=-63
a=-63/-9
a=7
Hence final answer is a=7.
Y = 2x + 2
Y = 2x -
Subtract
0 = 2
This makes no sense meaning the lines are parallel. Therefore there are 0 solutions.

if runner runs 92 miles in 8 minutes
? miles in 1 minute
?.8=92.1
?=92/8
?=11.5
Distance from start to look out point is calculated below
d1 = 8 3/4 miles - 0 miles = 8 3/4
Distance from look out point to giant boulder is,
d2 = 8 3/4 miles - 4 1/4 miles = 9/2 miles = 4.5 miles
Thus, the answer is equal to 4 1/2 miles. The answer is letter C.
Answer:
Step-by-step explanation:
29/36 = x/100
29*100 = 2900
2900/36 is 80.55555555555556
Simplify this to get 80.56
Therefore, 80.56% of carpenters showed up.
