The ratio of the number of mimi’s eminem cd’s to the number of rita’s eminem cd’s is 5: 8. rita has 18 more eminem cd’s than mimi. if rita gives 22cd’s to mimi, what will be the new ratio of the number of mimi’s eminem cd’s to rita’s?

M = Mimi’s cd’s 

R = Rita’s cd’s 

The ratio of the number of Mimi’s Eminem cd’s to the number of Rita’s Eminem cd’s is 5:8 mean: 

M / R = 5 / 8 

Rita has 18 more Eminem cd’s than Mimi mean: 

R = M + 18 

Now you have system of 2 equations with 2 unknow. 

M / R = 5 / 8 and R = M + 18 

M / R = 5 / 8 Multiply both sides by R 

M = 5 R / 8 Multiply both sides by 8 

8 M = 5 R 

Your system become: 

R = M + 18 

8 M = 5 R 

Replace R = M + 18 into equation 8 M = 5 R 

8 M = 5 ( M + 18 ) 

8 M = 5 M + 5 * 18 

8 M = 5 M + 90 Subtract 5 M to both sides 

8 M - 5 M = 5 M + 90 - 5 M 

3 M = 90 Divide both sides by 3 

M = 90 / 3 

M = 30 

Mimi has 30 cd’s 

Rita has: 

R = M + 18 = 30 + 18 = 48 

R = 48 

Rita has 48 cd’s 

If Rita gives 22cd’s to Mimi she will have 48 - 22 = 26 cd 

Mimi will have 30 + 22 = 52 cd 

The new ratio of the number of Mimi’s cd’s to Rita’s cd’s will be: 

M / R = 26 / 52 = 26 / 2 * 26 = 1:2

Where the white dots are is where your points should be plotted.a translation is simply just moving something from one place to another. in this case, you would move each plot point of the original shape 2 units up, and 5 units to the left.
