Q. 7□ Mark for Review7m=5(n+p)The given equation relates the positive numbers m,n, and p. Which equation correctly gives n in terms of m and p ?(A) n=7m5p(B) n=57m−p(C) n=5(7m)+p(D) n=7m−5−p
Start Equation:Step 1: Start with the given equation.7m=5(n+p)
Distribute 5:Step 2: Distribute the 5 on the right side.7m=5n+5p
Isolate n:Step 3: Isolate n by subtracting 5p from both sides.7m−5p=5n
Divide by 5:Step 4: Divide both sides by 5 to solve for n.n=57m−5p
Check Correct Option:Step 5: Check the options to find the correct one.Option (B) matches:n=57m−p
