Yes 7x+2x=35 that’s the problem I need help with
Question:
A reservoir in the shape of a right circular cylinder has a height of 84ft. If it to contain 79,200 L of water, find its radius.
Answer:
Step-by-step explanation:
Given
---- V
--- h
Required
Determine the radius
Convert volume to
The volume (V) of a cylinder is:
Substitute values for volume and height
Divide both sides by 84
Take as 3.14
Divide both sides by 3.14
Take the square root of both sides
<em>Hence, the radius is 3.26 ft</em>
Answer:
see explanation
Step-by-step explanation:
(A) Given
4(2x - 3) = 4 ( divide both sides by 4 )
2x - 3 = 1 ( add 3 to both sides )
2x = 4 ( divide both sides by 2 )
x = 2
(B)
As a check substitute x = 2 into the left side of the equation and if equal to the right side then it is the solution.
4(2(2) - 3) = 4(4 - 3) = 4(1) = 4 = right side
Hence x = 2 is the solution
-6 - 5 is -11.
Multiply that by 3 to get -33.
Your answer is -33.
