Answer:

34) A

35) C

36) D

Step-by-step explanation:

34) The perimeter of a triangle is equal to the sum of the lengths of its sides

Sides: (6.2p + 4.5q) + (3.4p - 0.7r) + (2.9r - 4.1q)

Combine like terms (same variables)

(6.2p + 3.4p) + (4.5q - 4.1q) + (2.9r - 0.7r)

9.6p + 0.4q + 2.2r

A

35)

Time possibilities

1 hour - $3 - $5 = $-2     No

2 hours - $6 - $5 = $1    Yes

3 hours - $9 - $5 = $4    Yes

4 hours - $12 - $5 = $7    Yes

5 hours - $15 - $5 = $10   Yes

6 hours - $18 - $5 = $13   Yes

7 hours - $21 - $5 = $16   Yes

8 hours - $24 - $5 = $19   No

9 hours - $27 - $5 = $22  No

The possible hours that Ms. Barnes can park are 2 - 7 hours

The only inequality graph that represents all of these values is C

36)

<h3>(-\frac{4}{7}) / (-\frac{3}{4}) * (-2\frac{1}{3})</h3>

Convert to improper fractions

<h3>(-\frac{4}{7}) / (-\frac{3}{4}) * (\frac{-7}{3})</h3>

Divide by finding the reciprocal

<h3>(-\frac{4}{7}) * (-\frac{4}{3}) * (\frac{-7}{3})</h3><h3 /><h3>\frac{16}{21} * -\frac{7}{3}</h3><h3 /><h3>\frac{-16}{9}</h3>

Convert back to a mixed number

-1\frac{7}{9}

D
