The square pyramid has a volume of 768 cubic inches. The height equals 1/6x and the base is just x. What is the value of x ?

Lunna [17]

The volume for a pyramid is $V= \frac{1}{3} Bh$ , where B is the area of the base and h is the height. We are given the volume, and the base and height in terms of x. Our formula then looks like this: $768= \frac{1}{3} (x)( \frac{1}{6} x)$ . Simplifying the right side we have $768= \frac{1}{18} x^{2}$ . Multiply both sides by 18 to get rid of the fraction and we have $13824= x^{2}$ , so x = 117.575

-18 + 2a = 2(3a + 1)

Nadusha1986 [10]

Answer:

a = -5

Step-by-step explanation:

Given

-18 + 2a = 2(3a + 1)

Expand the bracket on the right

-18 + 2a = 2 x 3a + 2 x 1

-18 + 2a = 6a + 2

Add 18 to both sides

-18 + 18 + 2a = 6a + 2 + 18

2a = 6a + 20

Subtract 6a from both sides

2a - 6a = 6a - 6a + 20

-4a = 20

Divide both sides by -4

-4a/-4 = 20/-4

a = -5

I NEED ASAP:<br> What is the value of x?

Vitek1552 [10]

Answer:

x=48

Step-by-step explanation:

10x-20+6x+8=180 set the equations together and to equal 180 since a line is 180 degrees

Get the variables together

10x-20+6x+8=180

-6x -6x

4x-20+8=180

add together -20 and 8

4x-12=180

add -12 on each side

4x-12=180

+12 +12

4x=192

divide all by 4

x=48
