2/3 times what equals 24?

Answers

Explanation

2/3x = 24

So we need to isolate the x by getting rid of 2/3 using the reciprocal and multiplying by it both sides as shown below

2/3x = 24
•(3/2). •(3/2)

X= 36

The number 24 is 2/3 times of the number 36.

What is Algebra?

A branch of mathematics known as algebra deals with symbols and the fine operations performed on them.

Variables are the name given to these symbols because they warrant set values. We constantly observe constant change in specific values in our day- to- day situations. But the need to depict these shifting values is ongoing.

In order to determine the values, these symbols are also subordinated to colorful addition, deduction, addition, and division computation operations.

We have to find 2/3 times what equals 24.

let the number be x.

So, 2/3 of x = 24.

2x/ 3 = 24

2x = 72

x= 72/ 2

x= 36

Thus, the required number is 36.

If F(x) = -3x-2 , what is F(-5)

A) F(-5)=13
B) F(-5)=-17
C) F(-5)=-13
D) F(-5)= 17

Answers

A, F(-5)=13. To show work, substitute the x in F(x) = -3x-2 with -5 to get F(-5) = -3(-5)-2. Then, following PEMDAS, multiply -3 and -5 first to get 15. So, you are left with F(-5)=15-2. 15-2=13.
