Answer:

3.75

Step-by-step explanation:

Set up the following ratio:

2400 watt-hours           1 day

-------------------------   =    ----------

9000 watt-hours           x days

Then do criss-cross-apple-sauce:

x*2400=9000*1

And then solve for x:

2400x=9000

x=9000/2400

x=3.75

Solve: negative 1 over 2 x + 1 = −x + 8 (5 points)
Naya [18.7K]
It is 14 because if you have -1/2x + 1 = -x + 8 you would combine the multiplied terms into a single fraction then subtract the one from both sides simplify till you get -x/2 = -x + 7 then you will add like terms so the x’s then you multiply all terms by two like 2(-x/2)= 2•7 then you can get 14.
