Answer:
6 phones and 18 accessories
Step-by-step explanation:
12P + 3.50A = 135
A = 12 + P
12P + 3.50(12 + P) = 135,
12P + 42 +3.50P = 135
15.50P = 93
P = 6 phones
A = 12 + 6 = 18 accessories
Answer:

The graph will be a horizontal line.
The answer is: "
41 / 11 " ; or, write as: "
41 : 11 " .
__________________________________________________________Explanation:__________________________________________________________72/99 = (72÷9) / (99÷9) = 8/ 11 .
So, 3.727272727272... = "3

" .
→ "3

" = [(11 *3) + 8] / 11 = (33 + 8) / 11 = 41 / 11 .
__________________________________________________________ "41 / 11" cannot be simplified any further; so the answer is:
__________________________________________________________ "
41 / 11 " ; or, write as: "
41 : 11 " .

Answer:
y = -9 or y = -4
Step-by-step explanation:
y^2 + 13y = -36
y^2 + 13y + 36 = 0
(y + 9)(y + 4)
y + 9 = 0
y = -9
y + 4 = 0
y = -4
Best of Luck!
