Select all the values that can be substituted for x to make the inequality true.

x + 2.4<8.6
A. 8.5

B. 0

C. 9.1

D. 5.7

E. 2.4

which one is correct?

I don't really know.

well, x < 6.2, so ...

To determine which values can be substituted for x to make the inequality true, we need to solve the inequality x + 2.4 < 8.6.

To do this, we'll isolate x by subtracting 2.4 from both sides of the inequality:

x + 2.4 - 2.4 < 8.6 - 2.4

Simplifying both sides:

x < 6.2

Now we can determine which values satisfy this inequality. We'll go through each option one by one and see if it satisfies the inequality:

A. 8.5: This value does not satisfy the inequality, as 8.5 is greater than 6.2.

B. 0: This value does satisfy the inequality, as 0 is less than 6.2.

C. 9.1: This value does not satisfy the inequality, as 9.1 is greater than 6.2.

D. 5.7: This value does satisfy the inequality, as 5.7 is less than 6.2.

E. 2.4: This value does not satisfy the inequality, as 2.4 is equal to 6.2.

Thus, the values that can be substituted for x to make the inequality true are B. 0 and D. 5.7.
