Answer:
Step-by-step explanation:
12 - 12x = -6x + 48
Add 12x to both sides. That eliminates the x term on the left side.
12 = 6x + 48
Subtract 48 from both sides. That eliminates the constant term on the right side.
-36 = 6x
x = -6
Answer:
m= (110 - 2(20)) / w
m= typical amount of money saved each week
w= amount of weeks in this time period
Step-by-step explanation:
you would take the $110 he had saved up and subtract the additional $20 from the past 2 weeks which would be $40 or 2 times 20, and then you would take that total amount, which is why it is in parentheses, and divide it by the number of weeks that Matthew had been saving for that time period where he saved $110.
For example:
If Matthew had been saving for 5 weeks what you would do is,
m= (110 - 2(20)) / w
m= (110 - 2(20)) / 5
m= (110 - 40) / 5
m= (70) / 5
m= 14
therefore if Matthew had been saving for 5 weeks typically he would have saved $14 every week
(keep in mind this is only if he had been saving for 5 weeks if he had been saving for any other number of weeks the answer would be different)

If you mean that you want to solve the equation for v, then all you need to do is to multiply both sides by 3:
Answer:
4
Step-by-step explanation:
The answer is four because 10% of the whole tray (40) is 4
Equation:
.1 * 40 = 4
1/2 times 1/2 = 1/4
therefore, 1/4 of her shoes are brown sandals
