To adopt a dog from an animal shelter, you must pay $90 for vaccinations, $75 to spay or neuter the dog, and $40 for a wellness exam by a veterinarian. a. write an expression in simplest form that represents the amount (in dollars) it costs to adopt x dogs. an expression is () dollars.

you must pay this for each dog, then you're multiplying each dollar amount by x. Ex: if you buy 1 dog, you pay 80 + 65 + 50. If you adopt 2, you pay (80 * 2) + (65 * 2) + (50 * 2).

So the answer is 80x + 65x + 50x...

BUT! You can simplify by adding the coefficients: 80 + 65 + 50 = 195.

Your answer is 195x.

Hope this helps! You can try with different values to make sure you understand it.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
