Answer:
I would assume its the third one because it makes a lot more sense than the other ones
Step-by-step explanation:
Given:
yesterday = 270
today = 216
yesterday's number of tickets sold is the basis of the percent of change. So, 270 is the 100%.
270 - 216 = 54 * value of the change in ticket sales
54/270 = 0.20 x 100% = 20% * percent of change
There was a 20% decrease in ticket sales.
=(120/48)
=5/2
=(4/2)+(1/2)
=2+(1/2) or 2.5
Answer:
x=2
Step-by-step explanation:
let the unknown number be x
now we are to find x regarding the question as an equation, let's form the equation to solve for x
the interpretation of the question is:
(x² + x)/3 = x
by collecting the like terms:
(x²+ x) = 3x
x² + x = 3x
x² = 3x - x
x² = 2x
x = 2
17 and -17
absolute value is just the distance the number is from zero
