Answer: 250 students.
Step-by-step explanation:
Let x students in 6th grade either purchased their lunch or brought their lunch from home on Monday.
According to the question,
24% of the students purchased their lunch.
⇒ (100-24)% of the student brought their lunch from home.
⇒ 76 % of the student brought their lunch from home.
But, Again according to the question,

⇒ x = 250
Therefore, there are total 25 students in the 6th grade.
Answer:
Step-by-step explanation:
m=marta's rope
d=dilbert's rope
3d-10=m
m+d=120
Then you can substitute equation 1 into the second one
(3d-10)+d=120
3d-10+d=120
4d-10=120
4d=130
d=32.5
m+d=120
m+32.5=120
m=120-32.5
A because the y intercept is -1, and the function is absolute value
