Answer:
17 is C
18 is add
19 is C
Step-by-step explanation:
Question 18 is worded a little weird.
so. (x^2)(x^3) = x^5, so you should add the expotents when you are multiplying them.

Sorry that they're sideways, it's the only way brainy would let me send them!!
Answer:
B.70
Step-by-step explanation:
For one or two angles are complementary angle(s), they have to equal 90°.
So, we need to find the larger angle, but what about the other?
Let x be the other angle and y be the angle we are looking for
x + y = 90
Lets look for x first, since one angle is ten less than four times the angle we are looking for or visa versa, we must:
y = 4x - 10
For an exchange, lets take out the y variable for another x variable:
So now we should have x + 4x - 10 = 90
Combine like terms and do cross equation :
x + 4x -10 = 90
5x - 10 = 90
Add 10 to both sides:
5x = 100
100/5 = 20
So <u><em>x=20</em></u>
<u><em></em></u>
Now for y which is what we are looking for,
y = 4x - 10
Since x is 20, plug it in
y = 80 - 10
y=70 is our larger angle
Answer:
Jersey cost (without discount)= $65
Step-by-step explanation:
<u>First, we need to determine how much he spent on the jersey:</u>
Jersey cost (with discount)= 83.39 - 37.89
Jersey cost (with discount)= $45.5
<u>Now, the original cost of the jersey:</u>
Jersey cost (without discount)= discount cost / (1 - discount)
Jersey cost (without discount)= 45.5 / 0.7
Jersey cost (without discount)= $65
