21-3q=9

-21 -21

-3q=-12

Divide bye 13 each side

Q=4

Answer 2

Answer:

15 - 3q + 6 = 9 (re-arrange)
15 + 6 - 3q = 9 (add)
21 - 3q = 9 (subtract -21 from both sides)
-3q = 9 - 21 (add)
-3q = -12 (divide both sides by -3)
q = +4

as part of her shop class, Jules made the figure below out of pieces of wood. how much spave does the figure she made take up?

Answers

I suppose you want to find the Volume of this Figure.

you can separate it into two rectangular prisms
one that is 6 by 9 by 24
and the other that is 6 by 9 by 30

you multiply the three numbers to get the volume of each rectangular prism.
6 * 9 * 24 = 1296
6 * 9 * 30 = 1620

then we add the two numbers we got to get the overall volume of the figure
1296 + 1620 = 2916

Therefore the Figure takes up 2916 cm^3 of space.

What is 791=1/2h (26.5+30)

Answers

Following the order of PEMDAS, start with what's inside of the parenthesis, adding 26.5 with 30 ---> 791 = 1/2h(56.5)
You need to get h on one side of the equation by itself. To do this, divide the whole equation by .5 (which is the same as 1/2), canceling out the 1/2 on one side of the equation. 791/.5 = 1/2h(56.5)/.5 ----> 1582 = h(56.5)
Next, divide the entire equation again by 56.5. 1582/56.5 = h(56.5)/56.5
---> 28 = h
Your final answer is h = 28. To check this, plug 28 into the equation where the value h is.
