Answer:
x = 55
y = 45
Step-by-step explanation:
In similar triangles, the ratio between similar sides are the same. So,
AB/ED = BC/EF = AC/DF
Substitute values that they give
6/15 = 18/y = 22/x
Solve 6/15 = 18/y by cross-multiplying
6y = 15*18 = 324
Divide both sides by 6
y= 45
Solve 6/15 = 22/x by cross-multiplying.
6x = 22*15 = 330
Divide both sides by 6.
x = 55
Because there is some dispute between the answers, let's check the ratios.
6/15 = 18/45 = 22/55
0.4 = 0.4 = 0.4
True, x = 55 and y=45
whichever number you pick (5-50) is represented by 'X'
'X' will be the amount of money you saved a week
The weeks are going to be represented by 'Y'
so the formula would be-
'X' x 'Y'= The amount of money saved over 4 years of high school
So you have to get the number of weeks in four years and multiply it by the number that you selected and that should give you the answer.

Answer:
8 (n - 3) = 65
Step-by-step explanation:
the difference of a number and three means n - 3
8 times the difference of means that it will be 8 and then parenthesis the next terms that are said, so 8 (?)
is sixty-four means = 64
so put it together and you have 8 (n - 3) = 65
