It would be: - 2 - (-10) = 5x - 12
= -2 + 10 = 5x - 12
= 8 + 12 = 5x
= x = 20 / 5
= x = 4
35 :) If you change the percent into a decimal (0.70) and multiply that by 50, you will get the answer!
Answer:
Step-by-step explanation:
Given
Required
Determine an equivalent expression
Express 81 as 
Apply law of indices
Hence:
You could solve this using a proportion or just by common sense.
Proportion: 8/12 = x/126
Cross multiply: 12x = 1008
1008/12 = 84
Or the common sense route is just dividing 12 by 8 then multiplying the answer by 126. Either way, you get the same answer. Hope this helps! :)
