Write the word sentence as an equation. Four less than one-half of a number m is equal to a number n

Question

I need this for an exam I have on the 20th

Answer 1

Let's solve this by dissecting the individual phrases:

"Four less than..." This means we will be subtracting 4 from some quantity: - 4

"One-half of a number m..." This means we will be taking some number, m, and halving it: (1/2)m

"...is equal to a number n." This means the previous 2 phrases combined will equal some number, n: = n

By combining all three phrases, the equation becomes:

(1/2)m - 4 = n
