Greater then or less then
Answer:
Step-by-step explanation:
Use proportions to solve.
Corresponding sides have same ratio.
<u>Question 1</u>
- (6x + 3)/17 = (8x - 1)/21
- 21(6x + 3) = 17(8x - 1)
- 126x + 63 = 136x - 17
- 10x = 80
- x = 8
<u>Question 2</u>
- (x + 8)/21 = 32/28
- x + 8 = 21*8/7
- x + 8 = 24
- x = 24 - 8
- x = 16
6x-18
you pretty much h just multiply both the first part of the parentheses by the number outside, then the second :)
I think it's A. I can't really see the graphs clearly. It's the one that crosses at (15,2)
2x-438 = -438+2x= 2(x-219)
