some ? i think its around 75.00 but i'm no good at math.

He will earn about $120  if he walks 13 single dogs and 9 sets of two dogs .

Step-by-step explanation:

Given : Brian's going to charge each dog owner $4.50 to walk one dog and $6.75 to walk two dogs.

If he walks 13 single dogs , then amount earned = 13 × $4.50

= $58.5                             (1)

If he walks 9 sets of two dogs, then amount earned = 9  × $6.75

=$60.75                             (2)

Add (1) and (2)

The total amount he earned =  $58.5 + $60.75              

= $119.25 ≈ $120

Hence, he will earn about $120  if he walks 13 single dogs and 9 sets of two dogs .

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
