I think of a number. I multiply it by 7. I add 12. The result is 40. What is the number I am thinking of?

1 answer:

8 0

The number that you are thinking of is 4. To get this answer I did the opposite of how you received your answer.
40 - 12 = 28
28 ÷ 4 = 7
The number that you are thinking of is 4.

1.A rectangle is 6 inches longer than its wide.Write and simply an expression for the perimeter of the rectangle.

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.
