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.

To make adding our two fractions easier, we need to make sure they have like denominators.

Now that the denominators of our probabilities are the same, we can add them together to get our answer.

or 
Answer:
-15 + 10x
or
10x - 15
(either one works)
Step-by-step explanation:
You mean you just want me to expand it?
Ok.
Multiply -5 by 3 and -2x.
(-5)(3) = -15
(-5)(-2x) = +10x
Add those together:
-15 + 10x
or
10x - 15
For this case we must write in algebraic symbology the expression described above:
We have an equation, then:
- x squared plus y squared:

- minus 2x plus 7y plus 1:

- equals zero:

We construct the equation:

Answer:

Answer:
22 1/2
Step-by-step explanation:
2/3x=15
x=15/2/3
x=15*3/2
x=45/2
Therefore, x=22 1/2
