Answer:

15. a,    16. ∠GOH = 26

Step-by-step explanation:

15. A straight angle looks as a line.

16. ∠GOI = ∠GOH + ∠HOI

47 = ∠GOH + 21

∠GOH = 47 - 21 =26

∠GOH = 26

NEED HELP!!! :( Math!!!
IrinaVladis [17]
The "divisor" in synthetic division is most conveniently the value of the zero of the binomial term. Here, that is x=5. You also need to make sure you include all of the coefficients in the "dividend", putting zero where terms are missing.

The appropriate choice is A.

Please help! Explain how to solve!
Gnesinka [82]
So this one is a little tricky because in order to solve you need to combine like terms. The only problem is that two fractions don't have the same denominator.
This is what you do.
2/3 - 1/9
= (2*9) - (1*3) / 3*9
= 18 - 3 / 27
= 15/ 27
Simplify.
5/9 + y = 7/9
Now since you need to isolate the variable you have to subtract 5/9 from both sides. Since the denominator is the same you can just subtract the numerator. 
So y = 2/9
I hope this helps love! :)
