Answer: C
Step-by-step explanation: Round to the nearest 100
Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
Answer:
x = -10
Step-by-step explanation
5x+7(-3x-14)=162
First, 5x -21x - 98 = 162
Then, combine like-terms, -26x - 98 = 162
After that, add 98 to 162, and you'll end up with 260.
Finally, you'll wanna divide the -26x to the 162.
You'll end up with x = -10
