The answer is 5 months, with the cost of $85. You can find this answer by first writing the charges as 12x + 25 and 10x + 35. Then, you set them equal to each other and solve to find x, which is the number of months.
12x + 25 = 10x + 35
- 10x
2x + 25 = 35
- 25
2x = 10
÷ 2
x = 5
Now that we know what x is, we can substitute it in and get 10(5) + 35 = 50 + 35 = 85.
I hope this helps!
Answer:
Step-by-step explanation:
(A)
A=hw, h=1.5w
A=1.5w^2
(B)
A=(h+8)(w+8), h=1.5w
A=(1.5w+8)(w+8)
A=1.5w^2+12w+8w+64
A=1.5w^2+20w+64
Answer:
u=5.23
Step-by-step explanation:
Answer:
x is 7, y is -1
Step-by-step explanation:
x+7y=0
2x-8y=22 -> divide both sides by -2
x+7y=0
-x+4y=-11
Eliminate one of the equations by adding the equations.
11y=-11
y=-1
Substitue the value of y into te equation
x+7*(-1)=0
x=7
The factored form would be
2(x + 1)(3x + 1)
