Solve the problems:
2 1/2 + x = 5 1/3
2 4/15 - z = 1 2/3
y - 6 7/8 = 2 1/16

2 1/2 + x = 5 1/3

x = 5 1/3 - 2 1/2

x = 16/3 - 5/2

x = 32/6 - 15/6

x = 17/6

x = 2 5/6

2 4/15 - z = 1 2/3

-x = 1 2/3 - 2 4/15

-x = 5/3 - 34/15

-x = 25/15 - 34/15

-x = - 9/15

-x = -3/5

x = 3/5

y - 6 7/8 = 2 1/16

y = 2 1/16 + 6 7/8

y = 33/16 + 55/8

y = 33/16 + 110/16

y = 143/16

y = 8 15/16

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
