Answer:
He paid $1.11
Step-by-step explanation:
2.50 * 0.4 (he paid for 40% of the original price, since it was a 60% discount) = 1
1 * 0.11 (11% sales tax) = 0.11
1 + 0.11 = 1.11
20% off means you paid only 80% of the original price.
0.8x=40
x=40÷0.8=50
so the original price is 50
In algebra a term is a single number or letter so in this 5
x^2
-10xy
3y
y^2
-1
these are all the terms
Step 1: All angles in a triangle must add up to 180! Therefore, in the upper triangle, add up the two you know 85+35=120 so the missing angle is 60.
Step 2: Bottom triangle. Your new angle above (60) is the pair of the opposite angle - so it too is 60. So now you know 2 of the 3 angles: 60+64=124 Subtract that from 180 and you get 56...which is the answer for ?
