Answer:

2.) 3/8

3.) 3/8

4.) Couldn't read this one, too blurry

5.) 5/12

6.) 3/10

7.) 5/12

8.) 1/8

9.) 1/5

10.) 1/8

11.) 1/4

Step-by-step explanation:

So the thing about subtracting fractions is that you have to have the same denominator for both of them. (that's the number on the bottom.) So number 3 is 7/8 - 1/2. You're gonna wanna multiply 1/2 by four, for both the top and bottom number. This creates 4/8. Now you can subtract them! 7-4 = 3, and thus the answer is 3/8. You never, <em>ever</em> subtract the denominator: only the numerator.

A new video game is expected to sell 100 copies the first hour at a local game store. After that, the sales will follow the func
Mazyrski [523]
To answer this you need to make simple thought experiment. Since the number of sales after time passes cannot go negative (note that rate at which copies are sold can drop over time but total number cannot) that means that you are adding number of sales at first hour and during first hour.

first option cannot be the answer because you are subtracting 100 copies to total number of sold copies which is not logical.

The answer is D)   s(x) = 100 + 12(x-1)
after 1 hour (if you replace x with 1 in equation above) you will get 100 copies which matches conditions in the text.

(-9a? +12a - 10)+(9a? +10)<br><br> I need help with this test
stiks02 [169]
I think the answer would just be 12a because -9a? And +9a? Would cancel out and the -10 and +10 would cancel out so all that is left is the 12a
