Alfred Gilmore · Answer 1

P = 2L + 2W

L = W + 6

P = 2 (W + 6) + 2W

P = 2W + 12 + 2W

P = 4W + 12

5 + 2 (3x + 4) + x

5 + 6x + 8 + x

5 + 8 + 6x + x

13 + 7x Stop Don't go any further. That's the 11th commandment: Thou shalt not combine unlike terms.

Paul has a long drive. If Shelly waits up she better have some snacks

4*65 + x = 500 The x stands for the number of miles left to go

270 + x = 500 Subtract 280 from both sides

x = 500 - 270

x = 230

Just so you know if he keeps going at 65 mph the amount time will be

230/65 = 3.53 hours.
