Answer:
160
Step-by-step explanation:
(2.5 x 2)+(1.5 x 2) =8 (perimeter of scale)
8x20 = 160
1/12
1/2 ÷ 6
is the same as;
1/2 × 1/6 = 1/12
25% decrease
Percent change can be found by doing difference/original
(950,000 - 712,500) / 950,000
= 0.25
There was a 25% decrease in the population
x=5
7x-10=25
+10 +10
7x=35
divide by 7 both sides
