Answer:
∠G, ∠HGI, ∠IGH
Step-by-step explanation:
» <u>Concepts</u>
To name an angle, you MUST include the vertex either in the middle or have it standing by itself. To clarify, you can either call this angle ∠G, ∠HGI, or ∠IGH because they all include the vertex, G, in the middle or by itself. You put ∠HIG, which is incorrect because the vertex <u>is not </u><u>I</u>.

Answer:Yes
Step-by-step explanation:
12/28
12÷4=3
28÷4=7
3÷7=0.4
27÷3=9
63÷3=21
9÷21=0.4
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
Rewriting 278-159=119, we get 159 + 119 = 278. The first term is 159. If we add 119 once, we get 278; if we add 119 again, we get 397; and so on. This is an arithmetic sequence.
