Answer:
140
Step-by-step explanation:
if 7 is 5% then 5*20 is 100 so 7*20 is 140
6. 52x
7. 0.5(n+5)
9. 33b-12
10. 17c+2
25 × x = 45
or 25÷100 × x= 45
multiplying both sides by 100 and dividing both sides by 25, we have x = 45×100÷25
therefore, x = 180
( if you use a calculator simply enter 45×100÷ 25)
