Answer:
Data in this table are written in decimal numbers. That means that they don't present the number of students voting for their favorite sport, but portion of student from that grade. Another way to write decimal numbers is in percentages. For example 30% of students is 0.30, 48% is 0.48 etc.
Now that we know this, looking at the table we can see that the correct answer is C.

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
