How to translate word problems and solve

20) 9x - 3

21) 9x + 60

22) 4x - 10

Tip: when it says "___ more/less than," at the beginning you add it at the end.

Step-by-step explanation:

23) 190 = .10x + 15.      x = the amount of copies you get for $190.

subtract 15 from both sides.

175 = .10x

divide by .10 on both sides.

1750 = x. You can get 1750 copies for $190.

24) 150w + .10m = 190.     m = miles   (w = week)

150 + .10m = 190

subtract 150 from both sides

.10m = 40

divide .10 on both sides.

m = 400. You can drive 400 miles in one week for $190.

25) Here we have to work backwards. Start off with a 1 variable equation. Since L = 2w + 2, let's replace that for the length.

P = 2w + 4w + 4. (4w + 4 because perimeter is 2l + 2w, you have to double the length as well)

Add the w's together and input known values.

124 = 6w + 4

Subtract 4 on both sides

120 = 6w

Divide 6 on both sides

20 = w.

Now we will find the length since we know the width using the equation:

124 = 2(20) + 2L

124 = 40 + 2L

Subtract 40 on both sides

84 = 2L

Divide 2 on both sides

42 = L.

26) Do the same thing as 25.

162 = 2w + 2(w + 63)

162 = 2w + 2w + 126

162 = 4w + 126

Subtract 126 on both sides

36 = 4w

Divide 4 on both sides

9 = w.

9 + 63 = L

72 = L

Hope this helps.

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
