Answer:
X=23
Step-by-step explanation:
You should know that a triangle =180 degrees
Add all your angles together and =180
66+2x+3+3x-4=180
add similar terms
5x+65=180
Move your 65 to the other side
5x=115
x=23
(Optional)
to check if your answer is right substitute your x and add all angles together you should get 180 degrees.

Answer:
- $70
- y = 25 + 0.9x
- $250
Step-by-step explanation:
1. 10% of $50 is $5, so the purchases would come to $50 -5 = $45. Added to the $25 membership fee, the total cost for the year would be
$45 +25 = $70
2. The member pays $25 even if no purchases are made. Then any purchases are 100% - 10% = 90% of the marked price. So, the total is ...
y = 25 + 0.90x
3. $25 is 10% of $250, so that is the amount the member would have to purchase to break even on cost.
If you like, you can compare the cost without the membership (x) to the cost with the membership (25+.9x) and see where those costs are equal.
x = 25 +0.9x . . . . . x is the spending level at which there is no advantage
0.1x = 25 . . . . . . . . subtract 0.9x
25/0.1 = x = 250 . . . divide by 0.1
2.50X.08=.2
tax is 20 cents
8 percent =.08 as a decimal. to get the decimal of a percent pretend 8 percent is an 8 with an invisible decimal point at its right. so 8% is 8.0. to get a decimal of a percent, move the point two times to the left, and you will put in a 0 for the blank. so its ._8, where he blank is 0 and so 8%=.08
