Answer:
The original price was $25
Step-by-step explanation:
where p is the original price of the shirt, the sale price of the shirt is .80p.
the sale price of the shirt is p - 5.
so you can use this equation:
.80p = p - 5
now solve for p.
.80p - 1p = -5
-.20p = -5
p = 25.
so the original price was $25 and the sale price was $20.
Assuming the 2nd one is 4a^2 - 20a +25, it is the one you're looking for. It factors to be (2a-5)^2
Answer:
Step-by-step explanation:
∠BCA=∠CAE (alternate angles)
∠CAE=x
41+102+∠BCA=180
∠BCA=180-143=37
so x=37°
