1. 5x + 6 = 2 + 3x
-3x. - 3x
-------------------------
2x + 6 = 2
- 6. - 6
-------------------------
2x = -4
---- -----
2. 2

x = -2

2. 2(6 -2y) = -1(4y-9)
12 -4y = -4y + 9
+4y. +4y
----------------------------
.12 /=\ 9
No solution

3. 2z-6 = 2(z+2) + 10
2z -6 = 2z + 4 + 10
2z -6 = 2z +14
-2z. -2z
-6 /=\ 14
No solution.

A cylinder's volume can be calculated by the formula V=Bh, where V stands for volume, B stands for base area, and h stands for h

Anastaziya [24]

Answer:

$h = 3x^5-3x^2-10\text{ units}$

Step-by-step explanation:

We are given the following in the question:

Volume of cylinder =

$V=Bh$

where B is the area of base and h is the height of cylinder.

Volume of cylinder =

$V = 6\pi x^7-6\pi x^4-20\pi x^2$

Base area =

$B = 2\pi x^2$

We have to find height of cylinder.

$h = \dfrac{V}{B}\\\\h = \dfrac{6\pi x^7-6\pi x^4-20\pi x^2}{2\pi x^2}\\\\h = 3x^5-3x^2-10\text{ units}$

Thus, the height of cylinder is $3x^5-3x^2-10$ units.

Answer:

2 and a half @ 2.5 inches (sorry i can't type the fraction)

Step-by-step explanation:

english is my second language so sorry if you doesn't understand:

(1/2, 1/4)=(x,y)

based on the graph shown that each grid on the y axis represents 1/4, that is the smallest scale stood in the y axis.

this means 2 grid= 1/4 x 2 = 1/2 @ 0.5 inches.

since the '5 months-hair-length' is above about 2 grid above 2 inch:

2 inch + 0.5 inch= 2.5 inch
