Answer:
46.03 = 46.030
Step-by-step explanation:
they are the same nub,er except they put another zero at the end of the one on the right
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
B.) 10x-5 is equivalent to 6x – 5 + x + 3x
