solve for x
5 = 1/5x - 3

Answers

Answer:

x = 40

Step-by-step explanation:

5 = 1/5x -3

Add 3 to both sides

8= 1/5x

Multiply both sides by 5 to get rid of the fraction. (because no one likes fractions, lol)

40 = x

Check the math:

5= 1/5(40) -3

5 = 8-3

If I was simplifying the equation 56 - 21x + 39 - 14x I would do -21x - 14x to get -35x and then I would do 56 + 39 to get 95. So my simplified equation would be 95 - 35x.

Step-by-step explanation:

If you divided 4 from 60, you get 15.

Answer:

C ) 15

Step-by-step explanation:

The angles are vertical angles, which means they are equal to each other.

How is flipping the sign different then writing the inequality backwards

Answers

Answer: Much like when you divide by a negative number, the sign of the inequality must flip!

Step-by-step explanation: When you multiply both sides by a negative value you make the side that is greater have a "bigger" negative number, which actually means it is now less than the other side!

The list below shows the results of a survey of favorite ice-cream flavors among middle-school students.

18 students voted for chocolate.
12 students voted for strawberry.
20 students voted for vanilla.

What percentage of the students chose vanilla as their favorite ice-cream flavor?

A. 20%
B. 30%
C. 40%
D. 50%

Answers

Answer:

C. 40%

Step-by-step explanation:

There are 18 + 12 + 20 = 50 students in total.

20 students voted for vanilla.

So... 20 out of 50 students voted for vanilla.

20/50 = 2/5

2/5 = 40%

Answer:

C. 40%

Step-by-step explanation:

First you add them together:

12+18+20 = 50

Then, you times both sides of the equation by 2

24+36+40 = 100

You can see that 20 changed to 40, and that's the answer!

Babe Ruth was a famous baseball player in the 1920s. He made a salary of $80,000 in 1930, which was considered outrageous because it was more than President Hoover made ("I had a better year than he did" was Ruth's supposed response).
