Answer:
x = 4
Step-by-step explanation:
The steps we need to take:
1. Simplify left side.
2. Separate the variable and its coefficient from constants
3. Divide both sides by the coefficient to find "x
1) Simplify left side.
5(3x - 4) + 12 = 52
15x - 20 + 12 = 52
15x - 8 = 52
2) Separate the variable and its coefficient from constants by adding 8 to both sides.
15x - 8 + 8 = 52 + 8
15x = 60
3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)
15x / 15 = 60 / 15
x = 4
Answer:
V =298.49625 in^3
Step-by-step explanation:
Volume of a cylinder is given by
V = pi * r^2 *h
We know the diameter so we can find the radius
r = d/2 =6.5/2 = 3.25
and we know the height =9
V = pi * (3.25)^2 *9
V = pi*95.0625
If we approximate by 3.14
V = 3.14*95.0625
V =298.49625 in^3
It doesn’t make any difference whether or not the data is grouped, the mean is the same. So b. false.
(4x + 7)- (8- 3x) written in standard form is 7x-1 :)
