To find the unit rate, 391/17 gives us 23$ per hour time 13 hours is 299$ total.
Answer:
x = 11/3
Step-by-step explanation:
x - 2/3 = 3
³⁾x = ³⁾3 + 2/3
3x = 9 + 2

x = 11/3
Answer:
$20,800
Step-by-step explanation:
1st
multiple the amount he makes an hour by the hours he works
10×40 = 400
2nd
there is 52 weeks in a year
so multiple the total he earns by 52
400×52=20,800
First of all, we have to observe that the expression makes sense only if
otherwise, you'd have zero denominators, which are not allowed. So, assuming , let's sum the two fractions at the left hand side:
Again, since we're assuming , we can multiply both sides by to get
This equation has solutions and , but we can only accept the first, since 1 is a forbidden value.
So, the only solutions to this equation is
