Sure! Let's find the values of the algebraic expressions when M = -3.
(a) 2m - 5
Substituting M = -3 into the expression:
2(-3) - 5
Simplifying, we get: -6 - 5= -11
Therefore, when M = -3, the value of 2m - 5 is -11.
(b) 10m
Again, substituting M = -3 into the expression:
10(-3)
Simplifying, we have: -30
So, when M = -3, the value of 10m is -30.
(c) 8m - 6
Once more, substituting M = -3:
8(-3) - 6
Simplifying, we get:
-24 - 6 = -30
Therefore, when M = -3, the value of 8m - 6 is -30.
To summarize:
(a) 2m - 5 is -11 when M = -3.
(b) 10m is -30 when M = -3.
(c) 8m - 6 is -30 when M = -3.
