Answer:
10y³
Step-by-step explanation:
y appears 3 times.
Which means y is multiplied by itself 3 times.
Then, simplify 5 x 2, which is 10, then put y3 after 10.
Direct variations can be set up as proportions
5/75 = 8/x....5 hrs to 75 dollars = 8 hrs to x dollars
now we cross multiply
(5)(x) = (75)(8)
5x = 600
x = 600/5
x = 120 <== so he makes $120 for working 8 hrs
another way...
75/5 = 15..so he makes 15 per hr
15 * 8 = 120
Just add the volumes of two boxes
volume of first box will be L×B×H
⇒6×5×5=150
volume of second box will be 4×4×4
= 64
total volume will be 150+64
= 214
You could turn the fraction into a decimal and then see which is bigger
