1.9x10x10x10+2.3x10x10x10x10
This is one way you could write out the steps
f(x) = -2x^2 - 5
f(2) = -2(2)^2 - 5
f(2) = -2(4) - 5
f(2) = -8 - 5
f(2) = -13
Answer:
No, You can't. You have to make their denominators equal!

Step-by-step explanation:
So first, you make their denominators equal!

Multiplying both the numerator and denominator with the same number results in the same fraction, just un-simplified
So, we input it!

There you go!
Hope you get better at math!(gets wayyyyyyyyyyy...y more complicated later)
Hope this helps!
See Ya!
P.S. Stay Safe!
Let

be the number of hours that the waitress works in the evening.
We know for our problem that she works

in the afternoon and that she works <span>1.75 hours less in the afternoon than in the evening, so:
</span>

<span>Since </span>

, we can rewrite our expression:


We can conclude that she works 3.375 hours in the evening, or expressed as a mixed fraction:

hours.
Here is what the answer to your question is:
7x10x1=70
