Dafna1 [17]2 years ago
4 0

Answer:

r = -3

Step-by-step explanation:

We need to isolate r...

-8r+12=36

Subtract 12 from both sides

-8r=24

Divide both sides by -8

r= -3

We can check this answer...

-8r+12=36

-8(-3)+12=36

24+12=36

36=36 --> correct!

r = -3

What is 3 1/4 x 1 1/2 x 9?
IRISSAK [1]
Hey there!

First we multiply 3 1/4 x 1 1/2:

3 1/4 = 13/4 and 1 1/2 = 3/2

13 X 3 = 39
4 x 2 = 8

39/8 in simplest form = 4 7/8

Next, multiply 4 7/8 x 9:

4 7/8 = 39/8 and 9 = 9/1 (since it is one whole)

39 x 9 = 351
8 x 1 = 8

351/8 in simplest form is 43 7/8.

Your final answer is 43 7/8.

Hope this helps you.
Have a great day!
