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
Percent increase/decrease is:
(Change/original amount)x100
(.25/2.35)x100= 10.6%
(4x+6)(2x-5)
= 8x^2 - 20x + 12x - 30
= 8x^2 - 8x - 30
It is 45 because angle EBC is congruent to CDE (x) because of a rule called alternate angles. so x= 45°
Answer:
x=4+5yif sum is increased by 3 (x+y+3), result is 31x+y+3=31minus 3 both sidesx+y=28x=4+5y subsiutute4+5y+y=284+6y=28minus 4 both sides6y=24divide by 6y=4sub backx=4+5yx=4+5(4)x=4+20x=24the numbers are 24 and 4
