We are given the equation:
0.6 x + 4.8 = 7.2
In this case, the multiplication property of equality states
that whatever is multiplied on one side should also be multiplied on the other
side. Now we need to find the number that will make everything a whole number,
in this case 5. Multiply everything by 5:
5 * (0.6 x + 4.8 = 7.2)
3 x + 24 = 36
However we can see that we can still further simplify the
equation by multiplying everything by 1/3:
(1/3) * (3 x + 24 = 36)
x + 8 = 12
or
x = 4
B = 2h
Area = 121
1/2 × b × h = 121
1/2 × 2h × h = 121
h × h = 121
h^2 = 121
h = square root of 121
h = 11
The height is 11 kilometers
Answer:
12
Step-by-step explanation:
Just divide. 3/4 is 3 divided by 4= .75
75 hundredths is the same as 75%
20/100 20 divided by 100=.20 which is 20%
14 divided by 25 is .56, or 56%
1/5 is 1 divided by 5 = .20 or 20 %
