and
substitute the equation in the inequality
Step 
<u>Convert 
to F</u>
substitute in the formula
Step 
<u>Convert 
to F</u>
substitute in the formula
therefore
the answer is the option
B. −30 < 5 over 9 (F − 32) < 130; −22 < F < 266
Part 1:
A. Like terms must have the same variable and exponent.
B. Give an example of two terms that cannot be combined: 7c and 4b
C. Write one complete sentence to explain why the two terms you wrote cannot be combined: 7c and 4b cannot be combined because they have different variables, and are therefore not like terms.
D. Use distributive property: 2(-4 + 6.1) + 3(5 - x)
2 * -4 = -8
2 * 6.1 = 12.2
-8 + 12.2 + 3(5 - x)
3 * 5 = 15
3 * x = 3x
-8 + 12.2 + 15 -3x
-8 + 12.2 = 4.2
4.2 + 15 = 19.2
19.2 - 3x is the simplest version.
Part 2:
A. Thor is wrong because, in step 4, he subtracted to isolate the variable when he should have divided.
B. 4x + 9 = 6
Step 1: 4x + 9 - 9 = 6 - 9
Step 2: 4x = -3
Step 3: 4x/4 = -3/4
Step 4: x = -0.75
Answer:

1.8
Step-by-step explanation:
The graph of the problem is plotted using Asymptote and attached.
From the graph:
- 6 Families had 0 Pets
- 3 Families had 1 Pets
- 3 Families had 2 Pets
- 6 Families had 3 Pets
- 1 Family had 4 Pets
- 1 Family had 5 Pets
There are a total of 20 families.
