The price of an item yesterday was $120.Today the price fell to $78 find the percentage decrease
2 answers:
To find percentage decrease, we need to see how "much" of 120 was taken off.
So, let's call the percentage x (the percentage in decimal form).
120 * x = 78
so,
78/120 = x
.65 = x
So, our percentage in decimal form is .65, to get it to an actual percentage, we multiply it by 100 (since a percentage is out of 100)
The percentage decrease is 65%
The answer is $120.00-$78.00=$42.00

If n = number of hours and the equation is 174 + 58n then the answer is 3 hours
174 = 58n
÷ 58
3 = n
5x+20+16
the expression is 5x+36
They are vertical angles, thus they are equal to each other:
5x + 12 = 6x - 10
22 = x
x = 22
