The sales tax is 18 ×
, which is 1.26
The DVD + sales tax is:
18 + 1.26
= 19.26
The total price will be $19.26. She has $20, so she will have enough money
Answer:
The answer is B
Step-by-step explanation:
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>
Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:
If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
Now we can substitute
m for the slope, and use any points to plug in
and
.
Hope this helps! :^)
A=10, B=11, C=12, etc.
Now, the "only" thing that remains to do is solving the above equation.
While making this problem I only made sure it has a solution. I didn't try to solve it myself and I didn't know it will end up with such "convoluted" polynomial. Sorry to everyone who tried to solve it... m(_ _)m
I think the best way to approach it is using the rational root theorem since we know that . Moreover we can deduce that since there is and .
After you succesfully solve it, you should get the answer .
