What is one-tenth of 24

Answers

What is one-tenth of 24?

1/10 × 24/1

1 × 24 = 24
10 × 1 = 10
24/10

24 ÷ 10 = 2.4

2 × 10 = 20
24 - 20 = 4
2 2/5

one-tenth of 24 is 2.4 or 24/10 or 2 2/5.

divide 24 by 1/10
24 ÷ 1/10 = 2.4

Which of the following equations has infinitely many real solutions? A. 4x + 1 = x - 1 B. 4x + 1 = 4x - 1 C. 4(x - 7) = 4x + 28 D. 4(x - 7) = 4x - 28

Answers

The equation that has infinitely many real solutions is:

B. 4x + 1 = 4x - 1

In this equation, when you simplify it, you'll find that it states 1 = 1, which is always true. This means there are infinitely many solutions because any value of x would make the equation true.
