Why is it necessary to apply inverse operations on both sides of the equals l sign when solving an equations

Answers

Take this example (cause it's easy to explain)

10+5x=15x

To solve it we have to minus five on both side. We have to do this because we need to isolate the variable (in this case x) on the one side so we can divide and solve.

You would -5x (inverse from positive 5) from both sides on this because whatever you do to one side you have to do to the others to make it equal. In this case the answer would be x=1 (again cause it's easy lol.)

I hope this helps you!

What is the next letter? azbycxd

What is the mean of the data set? I got 177 when i added up the numbers but what would i divide 177 by?12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18

A.14.00

B.14.75

C.15.75

D.13.50

Answers

If you would like to know the mean of the data set, you can calculate this using the following steps:

The mean of the data set is the sum of all the data values divided by the number of these values.
  
12, 17, 16, 10, 20, 13, 14, 14, 12, 12, 19, 18

12 + 17 + 16 + 10 + 20 + 13 + 14 + 14 + 12 + 12 + 19 + 18 = 177
the number of data values: 12
177 / 12 = 14.75

The correct result would be B. 14.75.

Jamie, John, and Jake are on the prom committee. They are responsible for blowing up the balloons for prom night. John can blowup a balloon every 15 seconds while it takes Jamie and Jake 20 seconds per balloon. If 1 out of 80 balloons are found to be defected after they are inflated, Identify the expression which represents the number of balloons inflated per hour.A) 592.5x
B) 592.5 - 1/80x
C) 600x - 1/80
D) 600 - 1/80x

Answers

First, pass all the rate of inflation to ballons/hour

John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h

Then sum the rates to obtain the total rate

Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h

If it passes x hours the number of ballons inflated is 600*x

The number of ballon defective are 600*x/80

The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
