Answer:
8) x = 5.41
9) x = 45
10) x = 2.25
Step-by-step explanation:
8) 17/15 = 10/(2x-2)
150 = 34x - 34
reduce:
34x = 184
x = 5.41
9) 6/16 = (x-12)/(2x-2)
16x - 192 = 12x - 12
reduce:
4x = 180
x = 45
10) (x-9)/15 = (2x-9)/10
10x - 90 = 30x - 135
reduce:
20x = 45
x = 2.25
Answer:11.9090909
Step-by-step explanation:
What you are asking is x + 30 ÷ 11 = 1
x + 30 ÷ 11 = 1
Simplify
x + 30/11 = 1
Subtract 30/11 from each side
x + 30/11 - 30/11 = 1 - 30/11
x = -19/11
Answer:8.75
Step-by-step explanation:
Well, I can't see the choices, but to estimate that, I would round 0.48 up to 0.5, and round 591 down to 590. Then you can just half 590, which results in 295. Hope this helps!
