Answer:

a) 3x - 6x^2y + 2xy - 2x

b) 4x^2 <u>- 3y </u>+ 2x <u>+ 7y</u>

Step-by-step explanation:

Like terms is when the terms are the same.

For example, 3x and -2x would be like terms (both have x).

Not like terms would be 4x^2 and +2x (one is just an x and the other is x^2).

The Holcombe family went out to dinner
Jet001 [13]

Answer:

$13.77 per person in the family

Step-by-step explanation:

Cost of the meal = $54.65

Sales tax rate = 8%

Sales tax amount = 8% of $54.65

= 8/100 × 54.65

= 0.08 × 54.65

= $4.372

Tip = 18% of $54.65

= 18/100 × 54.65

= 0.18 × 54.65

= $9.837

Total cost of the dinner = Cost of the meal + Sales tax amount + Tip

= $54.65 + $4.372 + $9.837

= $68.859

There are 5 people in the Holcombe family

What was the cost per person for the meal, including sales tax and tip?

cost per person for the meal, including sales tax and tip = Total cost of the dinner / total number of people in the family

= $68.859 / 5

= $13.7718

Approximately

$13.77 per person in the family
