Answer:
$120
Step-by-step explanation:
Set the cost of the article pre-tax as x.
<em>x + 0.15x = 138</em>
<em>1.15x = 138</em>
<em>x = 138/1.15</em>
<em>x = </em><u><em>$120</em></u>
<u><em /></u>
Answer: the cost of the article without taxes is <u>$120</u>.
I feel its either A. Cause you do 74x2=148 or D. Because 74x2=148 -254 =106
Answer:
D: g(x)=(x + 4)2+ 6 so yeah it's d
When two angles are a linear pair, the sum of their measures is 180°:
∡1 + ∡ 2 = 180°
Substituting the expressions for the angles, you get:
<span>5y − 8 + 12 + 6y = 180
Solve for y:
11y = 176
y = 176/11
Now, substitute this value in the expression for </span>∠2, which is the one we are interested in:
∡2 = 12 + 6y = 12 + 6×(<span>176/11) = 108°
When two angles are vertical angles, it means that they share the same vertex and they have the same measure, therefore:
</span>∡3 = ∡2 = 108°
Hence, the correct answer is <span>C) 108°. </span>
