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:
y= 3x +9
Step-by-step explanation:
m= 3
The y-intercept of the line that passes through the given point (0,9) is
9 = 0(3) + b
b= 9
The equation of the line that passes through the given point (0,9) is
y =mx +b
y = 3x +9
Answer:
56 and 43
Step-by-step explanation:
(x+13)+x = 99
2x+13 = 99
2x = 99-13
2x = 86
x = 86/2
x = 43
Smaller number = 43
Larger number is 56
Check
56-43 = 13
56+43 = 99
You're right the towo numbers are 1.5 and 3.5 so the answer would be 10
