Since the sides are congruent so are the angles (SSS) so 3x+3x+3x=180 because all the angles in a triangle add up to 180 degrees
9x=180
X=20
So the answer is x =20
If it was priced at $100 and had 30% off, it would cost
($100 - (30% of $100)) =$70.
If there was an additional 20% off, it would cost
($100 - (30% of $100) - (20% of 30% of $100)) = $56.
So the total savings is (100-56)/100=44%.
For $74.99, the answer is the same but the numbers are slightly different,
(74.99 - (30% of 74.99) - (20% of 30% of 74.99))/74.99 = 44%.
Drey makes $10 an hour plus $15 an hour for every hour of overtime. Overtime hours are any hours more than 40 hours for the week.
Part A: Create an equation that shows the amount of wages earned, W, for working x hours in a week when there is no overtime.
If there is no overtime, the equation is W = 10x.
Part B: Create an equation that shows the amount of wages earned, S, for working y hours of overtime. Hint: Remember to include in the equation the amount earned from working 40 hours.
At $10 per hour for 40 hours, the total is $400.
S = 15y + 400
Part C: Drey earned $490 in 1 week. How many hours (regular plus overtime) did he work?
490 = 15y + 400
490 - 400 = 15y
90 = 15y
90/15 = y
6 = y
Drey worked 46 hours in all.
