Multiply 6 and 8 which is 48cm
Answer:
5x - (x/y) = 18 when x=4 and y=2
Step-by-step explanation:
5x - (x/y)
When x=4 and y=2
Substitute the value of x=4 and y=2 into the expression
5x - (x/y)
5(4) - (4/2)
Multiply 5 by 4 and divide 4 by 2
=20 - 2
Subtract 2 from 20
=18
5x - (x/y) = 18 when x=4 and y=2
Lets find the unit rate of both of the shirts.
5 for 63
4 for 54
63/5 = 12.60
54/4 = 13.50
Now we have our unit rates!
Greg = $12.60 per shirt
Zachary = $13.50 per shirt
Greg's shirt were cheaper than his brothers, so it has a better cost.
