Answer: ? = 11 ft
Step-by-step explanation:
think of it as a rectangle, it still has right angle
2 sides would be parallel to each other:
6 ft + 9 ft = 15 ft
therefore 7 ft + 4 ft = 11 ft
U add all the numbers, and then u divide by the number of numbers 171/6 =28.5
First, set 2x+7 equal to 3x-7 since they are the same angle due to the parallel lines.
2x+7=3x-7
x=14
Then, since 2x+7 and 12y+1 equals 180, put it together to find y:
(2x+7)+(12y+1)=180
(2(14)+7)+(12y+1)=180
12y+1=145
12y=144
y=12
So, x=14 and y=12. Your answer should be C!
Answer:
18 =y
Step-by-step explanation:
56=38+y
Subtract 38 from each side
56-38=38-38+y
18 = y
The answer is the last one. The main goal is to get the initial velocity alone, and by solving that treat it like your solving an equation. I showed the process of how I got the answer attached. But if you want me to explain it, I am glad to do it.
