Select the expression below that is equal to 7(9 – m).
A.
7m – 63
B.
63 – 7m
C.
63 – m
D.
16 – m
Answer:
7(9 – m) can be simplified using the distributive property of multiplication over addition/subtraction, which states that a(b – c) = ab – ac.
Applying this property, we get:
7(9 – m) = 79 – 7m
Simplifying further:
7(9 – m) = 63 – 7m
Therefore, the expression that is equal to 7(9 – m) is option B: 63 – 7m.
