Correct Question:

Stan ran miles, which was fewer miles than Matt ran. Four students wrote and solved equations to find m, the number of miles that Matt ran. Which student wrote and solved the equation correctly?

Molly’s work:

Emma’s work:

Alysa’s work:

3 and two-fifths

Maddie’s work:

Molly's Work is correct

Step-by-step explanation:

Let S represent distance covered by Stan and M represent the distance covered by Matt;

Given that the distance covered by Stan is miles and it is miles less than that covered by Matt;

This can be represented mathematically as

By substituting for S;

This gives

By collecting like terms

becomes

Reorder

---- This is the correct equation

Solving further to get the distance covered by Matt;

Split fraction

Collect like terms

Add fraction (Take LCM)

Divide Fraction

Hence, the equation of the system is

and the solution is

Molly’s work is correct

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
