An equation is shown below: 5(2x - 8) + 15 = -15

Write the steps you will use to solve the equation and explain each step.

Answers

Answer 1

Answer: 5 (2×-8)+15= -15

distribute the 5 into (2×-8) and it becomes

10x-40 + 15 = -15

add -40 and +15

10× - 25 = -15

add +25 to both sides

10x= 10

divide both sides by 10

x = 1

Answer 2

Answer: 5(2x-8)+15=-15 -15 in both sides 5(2x-8)=-30 /5 2x-8=-6 +8 2x=2 /2 x=1 I hope it helps

What is the relationship between gross pay and net pay?

Answers

Your gross pay and net pay both have to do with taxes and the amount of money you earn, but they differ from one another:

Gross pay: This is the total amount of money you earned during the pay period, your salary multiplied by the number of hours you worked.

Net pay: This number will be less than the gross pay because this is how much you actually take home after taxes are taken out of your check.

An automobile engineer is redesigning a conical chamber that was originally specified to be 12 inches long with a circular base of diameter 5.7 inches. In the new design, the chamber is scaled by a factor of 1.5.

Answers

Answer:

The volume of the original chamber is 102.02cubic inches. This is 242.47 cubic inches less than the volume of the new chamber.

Hope this helps! I got it right on the Plato/Edmentum mastery test ♡

You can figure out the new cone or get the volume of the original cone and use the fact that if two objects are proportional in their dimensions, then the volume is proportional to the cube of the ratio of any of their lengths. E.G., doubling a sphere diameter increases the volume by 2 cubed = 8.

on a farm, 4 1/2 out of every 15 acres of land are used to grow crops. Wheat is grown on 5/8 of the land used to grow crops. What percentage of the total area of the land on the farm is used to grow wheat?

Answers

The answer is 18.75% (I THINK, I'm not very good at maths!) here's how I worked it out:

4.5 + 4 1/2 so for the first part it is a fraction 4.5/15 you then multiply this to 5/8 and get 225/120 which you can then simplify to 3/16 then you work out 3 divided by 16 and get 0.1875 and multiply this decimal by 100 to get the percentage, 18.75%.
