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

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)

$(-\frac{4}{7}) / (-\frac{3}{4}) * (-2\frac{1}{3})$

Convert to improper fractions

$(-\frac{4}{7}) / (-\frac{3}{4}) * (\frac{-7}{3})$

Divide by finding the reciprocal

$(-\frac{4}{7}) * (-\frac{4}{3}) * (\frac{-7}{3})$ $\frac{16}{21}$ * $-\frac{7}{3}$ $\frac{-16}{9}$

Convert back to a mixed number

$-1\frac{7}{9}$

Hope this helps :)
