5. Evaluate the expression [tex]$2\left(5-\left(\frac{1}{2} m\right)\right)-7$[/tex] where [tex]$m=4$[/tex].

A. [tex]-1[/tex]
B. [tex]-5[/tex]
C. [tex]1[/tex]
D. [tex]-3[/tex]



Answer :

Sure, let's evaluate the given expression step-by-step: [tex]\( 2\left(5 - \left(\frac{1}{2} m\right)\right) - 7 \)[/tex] where [tex]\( m = 4 \)[/tex].

1. Substitute the value of [tex]\( m \)[/tex] into the expression:
[tex]\[ 2\left(5 - \left(\frac{1}{2} \times 4 \right)\right) - 7 \][/tex]

2. Simplify the inner fraction:
[tex]\[ \frac{1}{2} \times 4 = 2 \][/tex]

3. Subtract the result from 5:
[tex]\[ 5 - 2 = 3 \][/tex]

4. Multiply the result by 2:
[tex]\[ 2 \times 3 = 6 \][/tex]

5. Subtract 7 from the result:
[tex]\[ 6 - 7 = -1 \][/tex]

So, the final result of the expression is [tex]\( -1 \)[/tex].

Based on the options given:
- The correct answer is [tex]\( -1 \)[/tex].
