Answer:
I'm pretty sure it's
yes, yes, no, yes.
I've never had to do this so I'm sorry if I'm wrong
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
Answer:
-88x^3
Step-by-step explanation:
1) distribute the "2x"
(8x+8x-98x-2x-4x)x^2
a) add all like terms in parantheses
(-88x)x^2
b) multiply -88x and x^2
-88x*x^2=-88x^3
hope this helps!
