Question

Which values make X over seven a whole number
X equals seven true or false
X equals 11 true or false
X equals 49 true or false
X equals -245 true or false

Answer 1

To determine if \( \frac{X}{7} \) is a whole number, we need to check if \( X \) is divisible by 7. We'll analyze each value:

1. **X equals 7**:
\[
\frac{7}{7} = 1 \quad \text{(whole number)} \quad \text{True}
\]

2. **X equals 11**:
\[
\frac{11}{7} \quad \text{(not a whole number)} \quad \text{False}
\]

3. **X equals 49**:
\[
\frac{49}{7} = 7 \quad \text{(whole number)} \quad \text{True}
\]

4. **X equals -245**:
\[
\frac{-245}{7} = -35 \quad \text{(whole number)} \quad \text{True}
\]

So the results are as follows:
- \( X = 7 \): True
- \( X = 11 \): False
- \( X = 49 \): True
- \( X = -245 \): True
