The value of Peter's house has risen 30% a year for the last 3 years. If the value of Peter's home 3 years ago was $110,000.00, what is the value now?

$99,000

Step-by-step explanation:

30/100×3=0•9

0•9×$110,000=$99,000

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

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses
