.53571429 exactly but if you want to round the answer is different
The answer will be
f(3)=3(3)+7
=9+7
=16
Answer:
Option C) 4 cubic inches is the volume of the rectangular prism.
Step-by-step explanation:
It is given that, 108 cubes with an edge length of 1/3 inch are needed to fill a rectangular prism.
Therefore, the volume of the rectangular prism is equal to the volume of the 108 cubes needed to fill that rectangular prism.
So, we need to find out the volume of those 108 cubes in order to find the volume of the rectangular prism.
The formula for finding the volume of a cube is given by,
Volume of a cube = a³
where a represents the edge length
We know that, the edge length is 1/3 inch.
⇒ a = 1/3
Volume of a cube = (1/3)³
⇒ 1/3 × 1/3 × 1/3
⇒ 1/27 cubic inches
To find the volume of 108 cubes :
⇒ 108 × volume of one cube
⇒ 108 × 1/27
⇒ 4 cubic inches.
∴ The volume of 108 cubes is the volume of rectangular prism which is 4 cubic inches (option C)
To find the equation of a line, you need to find the slope and y-intercept by using the slope formula and point slope formula.
First, let's find the slope. 11 + 5/9 - 1 = 16/8 = 2. Therefore, the slope is 2.
Then, plug it into the point slope formula.
y + 5 = 2(x - 1).
Distribute: y + 5 = 2x - 2
Subtract 5 on both sides: y = 2x - 7.
Your final equation, that you need to plug into your answer, is y = 2x - 7.

Answer:
x = 4
Step-by-step explanation:
2.5x +6 = 3.25x +3
-2.5x -2.5x
6 = 0.75x +3
-3 -3
3 = 0.75x
divide by 0.75 both sides
4 = x
or
x = 4
