Solving an equation like this means to find the value of the variable. Here, the variable is x. Solve the left side normally.
Given: 1/3(9 - 6x) = -11
Distribute: 1/3(9) + 1/3(-6x) = -11
When operating with constant numbers on a variable term, apply affects of the operation on the coefficient. So, 1/3(-6x) = -2x.
3 - 2x = -11
Isolate the variable: 3 - 3 - 2x = -11 - 3
-2x = -14
Since these are both negative, we can convert them both to being positive.
2x = 14
Simplify: 2x/2 = 14/2
<u>x = 7</u>
I think it is the first answer, but don't count on it! I'm not sure.
Answer:
100
Explanation:
Triangle’s angles add up to 180
180 - 65 - 35 = 80
Since a straight line is also 180, subtract 80 from it.
180 - 80 = 100
We are asked to find the equivalent of the expression given:
(3m⁻² n)⁻³
-----------
6mn⁻²
Perform distribution of power using power rule such as shown below:
3⁻³ m⁻²*⁻³n⁻³
-----------------
6mn⁻²
Perform product and quotient rule such as shown below:
m⁶ n²
--------
3³ *6*m*n³
Simplify,
m⁵
--------
162n
The answer is m⁵/162n.
Given:
The shape is square.
To find:
The surface area and volume of a square.
Explanation:
The length of each side of the square is "a" units.
The formula for the surface area of the square is,
The formula for the volume of the square is,
Using these formulas, we can find the surface area and the volume of the square that has side length "a" units.
For example:
Let the side length of 3cm for a square.
So, the dimensions are 3cm by 3cm by 3cm.
That is,
The Length is 3cm.
The breadth is 3cm.
The height is 3cm.
So,
The surface area of the square is,
Therefore, the surface area of the square is 54 square cm.
The volume of the square is,
Therefore, the volume of the square is 27 cubic cm.
