Hi there!
Given:
[tex]4m + \frac{23 + n}{p - 3} \\ m = 7 \\ n = 2 \\ p = 8[/tex]
In order to evaluate the expression with the given values of m, n and p, we must substitute then into the expression. Then we use the correct order of operations (PEMDAS) to calculate.
Let's substitute first!
[tex]4(7) + \frac{(23 + 2)}{(8 - 3)} [/tex]
Now find the numerator and denominator of the fraction.
[tex]4(7) + \frac{25}{5} [/tex]
Next up: multiplying
[tex]28 + \frac{25}{5} [/tex]
Divide the fraction.
[tex]28 + 5[/tex]
And finally add the integers.
[tex]33[/tex]
Hence, the answer is 33.
~ Hope this helps you!
