Answer:
1/2 or 0.50
Step-by-step explanation:
To find the probability of getting either blue or green on a spinner, we must add both probabilities together.
![\frac{3}{10}+\frac{1}{5} = ?](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D%2B%5Cfrac%7B1%7D%7B5%7D%20%20%3D%20%3F)
To make adding our two fractions easier, we need to make sure they have like denominators.
![\frac{1*2}{5*2} =\frac{2}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%2A2%7D%7B5%2A2%7D%20%3D%5Cfrac%7B2%7D%7B10%7D)
Now that the denominators of our probabilities are the same, we can add them together to get our answer.
![\frac{3}{10} +\frac{2}{10}=\frac{5}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B10%7D%20%2B%5Cfrac%7B2%7D%7B10%7D%3D%5Cfrac%7B5%7D%7B10%7D)
or ![0.50](https://tex.z-dn.net/?f=0.50)
C. 28 is the answer
Staring from the brackets we have 4+(-8) we can open the parentheses and get 4-8 and get -4. Now we can open the -7 up and now we have
-4 * -7 = 28
Hope this helps!
