For the past two weeks Matthew saved an additional $20 from his allowance. He saved $110 during this time period. Write an equation to determine how much money Matthew typically saves form his allowance.

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)

Hope this helps! Be sure to comment with any questions!

14 a week bro

Step-by-step explanation:

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
