Question

Which of the following values of x is true for the inequality below?
1.9 + x > 15

A.
x = 11.9
B.
x = 7.1
C.
x = 13.1
D.
x = 19.1

Answer 1

To solve the inequality \( 1.9 + x > 15 \), we first subtract \( 1.9 \) from both sides:

\[
x > 15 - 1.9
\]

Calculating the right side:

\[
15 - 1.9 = 13.1
\]

So the inequality simplifies to:

\[
x > 13.1
\]

Now we can evaluate the provided options:

A. \( x = 11.9 \) (not greater than 13.1)
B. \( x = 7.1 \) (not greater than 13.1)
C. \( x = 13.1 \) (not greater than 13.1)
D. \( x = 19.1 \) (greater than 13.1)

The only value of \( x \) that satisfies the inequality is:

**D. x = 19.1**
