Solve for x. *<br> (5x + 13)<br> (9x - 31)

ycow [4]

Answer:

x=11

Step-by-step explanation:

5x+13=9x-31

subtract 9 from both sides.

-4x+13=-31

you want to isolate the x value so subtract 13 from both sides.

-4x=-44

now divide both sides by -4.

x=11

The radius of a cylinder is doubled and its height is halved. Find the ratios of their surface areas.

Inessa [10]

Answer: 1:1

Step-by-step explanation:

Let r be the radius and h be the height of a cylinder.

Formula: Curved surface area of cylinder = $2\pi rh$

Now, if radius of a cylinder is doubled and its height is halved, then new radius will be R= 2r and new height will be $H=\dfrac{1}{2}$

Now, new surface area = $2\pi RH= 2\pi(2r)\dfrac{h}{2}= 2\pi rh$

Ratio of curved surface areas : $\dfrac{\text{Surface area}}{\text{New surface area}}=\dfrac{2\pi rh}{2\pi rh}=\dfrac{1}{1}$

Hence, the ratios of their surface areas = 1:1 .

marissa [1.9K]

Answer:

$x = -4$

Step-by-step explanation:

Take out 3x from both sides:

5x - 3x = 3x - 3x

2x = 0

2x + 9 = 1

Take out 9 from both sides:

9 - 9 = 1 - 9

0 = -8

Divide 2 from both sides:

$\frac{2x}{2} = \frac{-8}{2}$

$x = -4$
