If you want to easily find the solution you can use your calculator.
Just divide 77 by 110 and see the result.
77/110 = 0.7 = 7/10 = 70/100 = 70%
100% - 70% = 30%
Explanation
110*x=77
x=77/110, but the answer is not a percent
So 77/110 = ?/100 => ?=77*100/110=70 => 70%
But since 70% does not represent a percentage decreasement, we need to subtract it from the 100%
100% - 70% = 30%

the answer is C. -1
Step-by-step explanation:
-1 is the smallest number
You just do
3x=x+4
subtract x from both sides
2x=4
divide 2 from both sides
x=2
y=2+4
y=6
(x,y)= (2,6)
Let
us assume that Al’s frog jumped X inches.
Fred’s
frog jumped 7X inches.
Total
distance covered by both frogs is 56 inches.
Then
X+7X=56
8X=56
X=56/8
X=7
Fred’s
frog jumped=7X inches

= 7*7 inches</span>
