5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15

Step-by-step explanation:
They already have articulated a query and also gathered information unless you are searching only at the distribution of your results. Those who are ready to analyze your results for all are there.
Answer:
Step-by-step explanation:
50 + 12.50h = 143.75....where h = # of hrs
12.50h = 143.75 - 50
12.50h = 93.75
h = 93.75 / 12.50
h = 7.5 (or 7 1/2) hrs <====
Step-by-step explanation:
to "solve" this I need an equation.
this whole expression must be equal to something.
without that I can only try to simplify the expression.
remember that
a/b / c/d = ad / bc
so, here we have
3a/(((a²/x) - 1)(a/x - 1)) = 3a/(a³/x² - a²/x - a/x + 1) =
= 3a/(a³/x² - a²/x - a/x - a/a) =
= 3a/((a²/x² - a/x - 1/x - 1/a)×a) = 3/(a²/x² - a/x - 1/x - 1/a)
Answer: 30
Reason: you divide 60=2x which makes x=30
