If x + 3 = 11, what is the value of 5x?

Explanation:
To determine the value of \( 5x \), we first need to solve the equation \( x + 3 = 11 \). To isolate \( x \), we can subtract 3 from both sides of the equation: \[ x + 3 - 3 = 11 - 3 \] This simplifies to: \[ x = 8 \] Now, to find the value of \( 5x \), we multiply \( x \) by 5: \[ 5x = 5 \times 8 \] Calculating that gives: \[ 5x = 40 \] Thus, the correct value for \( 5x \) is 40. This confirms that the correct choice corresponds to this calculation.

To determine the value of ( 5x ), we first need to solve the equation ( x + 3 = 11 ). To isolate ( x ), we can subtract 3 from both sides of the equation:

[

x + 3 - 3 = 11 - 3

]

This simplifies to:

[

x = 8

]

Now, to find the value of ( 5x ), we multiply ( x ) by 5:

[

5x = 5 \times 8

]

Calculating that gives:

[

5x = 40

]

Thus, the correct value for ( 5x ) is 40. This confirms that the correct choice corresponds to this calculation.
