Answer:
Simplifying
10x + -2 = 118
Reorder the terms:
-2 + 10x = 118
Solving
-2 + 10x = 118
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + 10x = 118 + 2
Combine like terms: -2 + 2 = 0
0 + 10x = 118 + 2
10x = 118 + 2
<em><u>Combine like terms: 118 + 2 = 120</u></em>
<em><u>Combine like terms: 118 + 2 = 12010x = 120</u></em>
<em><u>Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.</u></em>
<em><u>Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12</u></em>
<em><u>Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifying</u></em>
<em><u>Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifyingx = 12</u></em>
Answer:
12,215 ft³
Step-by-step explanation:
The formula for the volume of a cone is:
V = (1/3)(area of base)(height).
Here the height is 9 ft and the diameter of the (round) base is 12 ft.
First we need to determine the area of the base.
If the diameter is 12 ft, then the radius is half that, or r = 6 ft. The area of the base is then A = πr², which in this problem is A = π(6 ft)² = π (36 ft²). Using 3.14 to approximate π, we get A = 4071.5 ft², which we will round u p to A = 4012 ft².
As before, the volume of this statue is V = (1/3)(area of base)(height), which here comes out to:
V = (1/3)(4072 ft²)(9 ft) = 12,215 ft³ (where I have rounded up to the nearest unit).
59-x=7(11-x)=59 yrs
59-x=77-7x
-x+7x-77-59
6x=18
x=18^6=3
so 3 years ago uncle's age is 7 times of Roy's age.
