Answer:

y =  \frac{1}{2} x + 5

Step-by-step explanation:

2x - 4y =  - 20 \\  \\  - 4y =  - 2x - 20 \\  \\ y =  \frac{ - 2}{ - 4}x  -  \frac{20}{ - 4}  \\  \\ y =  \frac{1}{2} x + 5

21 + 21 + 7 + 7 = 42 + 14 = 56

56 ft is your answer

I need help with this math problem
mr Goodwill [35]

Let X = number of minutes.

Plan A = 50 + 0.04X

Plan B = 60 + 0.02X


50 + 0.04X = 60 + 0.02X

Subtract 50 from each side:

0.04X = 10 + 0.02X

Subtract 0.02X from each side:

0.02X = 10

Divide both sides by 0.02

X = 10 / 0.02

X = 500

It will take 500 minutes.
