Answer:
Take 25 percent of the number and subtract that
Step-by-step explanation:
Basically, to decrease by 25 percent, you either multiply the number by .75 to get 75 percent of the original 100 percent. You do this because decreasing 100 percent (the original number) by 25 percent will give you 75 percent of the original number. If that's too confusing, take 1/4 of the original number and subtract that from the original number.
Answer:
RS = 17
Step-by-step explanation:
(23-2x) + (9x-5) = 39
23-2x+9x-5 = 39
7x + 18 = 39
7x = 21
x = 3
Given: RS = 23-2x
23 - 2(3)
23 - 6 = 17
