Answer:
D & E
Step-by-step explanation:
I believe you would need to divide 123.75 by 7.50.
The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours
Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation:
where r is the radius
Plug in the given area 161 in.²

Divide both sides by π to isolate r²

Take the square root of both sides to isolate r

Therefore, the radius of the circle is approximately 7.16 in.
I hope this helps!
When adding/subtracting fractions you need a common denominator, but you already have one, which is x-3. So in general:
a/c-b/c=(a-b)/c so you just have:
(2x-6)/(x-3) now if you factor 2 from the numerator
2(x-3)/(x-3) the (x-3)s cancel out leaving
2
However! Note that division by zero is undefined, so x cannot equal 3. (because both original fractions had denominators of x-3)
What this all means is that that expression will equal 2 for all real values of x other than 3.
You make an x= ... equation by moving 2y to the other side and /3 (in the first equation) then you fill in x into the second equation and you calculate y. If you have Y you fill it in in the first equation.
