Answer:
The answer is 6.56
Step-by-step explanation:
11.20 is the total. You multiply that by .15 and get $1.68 for the tip. You multiply $11.20 by .05 for the tax and get $.56. You add them together and get $13.44. You subtract that from $20.00 and get $6.56
Answer:
x = 3
Step-by-step explanation:
To answer for x first distribute the 4 in the parenthesis
4x + 1 - 5x = 2x +4x - 20
Next add or subtract the x's
-x + 1 = 6x - 20
Now subtract 6x and 1 on both sides to get x on the left and the rest on the right
-7x = -21
Lastly, divide -7 on both sides
x = 3
