Step-by-step explanation:
27x - 15y = 1350
15y = 27x -1350
y = 27/15 x - 1350/15
y = 9/5 x - 90
y = mx + b y intercept (b) = -90
y=0 x = 90 * 5/9 = 50 x intercept
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:
Answer:
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
