In 2014 the tenants at Jefferson school's Fall festival Was 650. In 2015 the attendance was 575. What was the percent change in
Over [174]

Answer: the percent change in attendance from 2014 to 2015 is 11.54%

Step-by-step explanation:

In 2014, the total attendance at Jefferson school's Fall festival was 650.

In 2015, the attendance was 575. The change in the number of attendees between 2014 and 2015 is 650 - 575 = 75

There was a decrease in the number of attendees between 2014 and 2015.

The percent change in attendance from 2014 to 2015 would be attendance in 2015 divided by attendance in 2014 and multiplied by 100. It becomes

75/650 × 100 = 11.54%

If 5(y+10)=40, find the value of 1\4y.
PolarNik [594]
Expand the brackets:
5y + 50 = 40
minus 50 on both sides to get 5y alone
5y = -10
divide both sides by 5 to find y
y= -2
∴ 1/4y = -0.5

What’s the difference between x and 4 is greater than 10
daser333 [38]

Answer:

There is a whole range of speeds at which you are allowed to drive, not just one. In cases like this where there is more than one correct answer, we use inequalities, not equations, to represent the situation.

Inequalities are mathematical statements that define a range of values. They are easily recognizable because they contain the symbols <, ≤,>, or ≥.
