Answer:
240.74
Step-by-step explanation:
y=±x*
I think first u need to find y or x and work from there
Answer:
XY = 18 units.
Step-by-step explanation:
The sum of the top and bottom lines = 2 * middle line, so:
6x + 1 + s = 2(4s - 2)
7s + 1 = 8s - 4
5 = s.
So XY = 4(5) - 2 = 18.
Hey there!
For Part A, all you need to do is write out an equation for how many dollars Andrew would make for x hours during regular hours (not overtime). Since he makes 6 dollars per hour, this will be 6x.
W = 6x
For Part B, create a similar equation for overtime hours. Overtime hours only apply after Andrew has worked 40 hours, so plug that into your first equation and add that to the second equation.
W = 6x
W = 6(40)
W = 240
S = 240 + 9y
For Part C, consider what we now know. If Andrew earns any money over 240 dollars (which is how much he earns after 40 hours), we know he worked overtime. So, we can just plug 330 into the second equation for S and solve for the number of additional hours he worked, y.
330 = 240 + 9y
– 240 – 240
<u>90</u> = <u>9y</u>
9 9
10 = y
Now, we can add up the initial 40 hours plus the additional 10 hours, which is 50 hours total.
Hope this helped you out! :-)
