Answer:

r = 4

Step-by-step explanation:

Simplifying

3r + -3 = 9

Reorder the terms:

-3 + 3r = 9

Solving

-3 + 3r = 9

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 3r = 9 + 3

Combine like terms: -3 + 3 = 0

0 + 3r = 9 + 3

3r = 9 + 3

Combine like terms: 9 + 3 = 12

3r = 12

Divide each side by '3'.

r = 4

Simplifying

r = 4

1) Order the animals by sleep time from least to greatest.
Zolol [24]
The way to line the animals is to put them in order going down. 0.433 56.3% 19/40 65.8%. Then you try to figure out what you need to convert so that you can get your answer. 56.3% changes to 0.563 because you move the decimal two places to the left. 65.8% changes to 0.658 and 19/40 is 0.475. 0.433 0.563 0.475 0.658. Now you compare each row to figure them out. When you do that your answer will be 0.433, 0.475, 0.563, and 0.658. I sleep about 9/24 of the day which is 0.375 and I will fit right befor 0.433.
