Answer:
18 and 72
Step-by-step explanation:
the smaller part can be assigned as x while the larger will be 4x. Both numbers need to add up to 90, giving the equation: 4x+x = 90
Solve:
4x+x = 90
5x = 90
x = 18
4x = 72
Answer:
the answer is 10a+11x
Step-by-step explanation:
2a+3a+5a=10a
3x+2x+6x=11x
(2/5) of (2/3) of students = 4/15 of students study French. Then 1-(4/15) = 11/15 of students do not study French. The ratio you want is
(4/15):(11/15) = 4:11

In a math expression "of" means "times".
Yes...there is truth to what ur classmate is saying.
first of all, to find the average of something, u add up all the numbers in ur data, and divide by how many numbers there are.
the midpoint formula : ((x1 + x2)/2 , (y1 + y2)/2)
so lets say ur points are (2,4) and (4,6)
so ur going to add ur x terms (2 + 4)....then divide by 2 (because there are 2 numbers)...so ur basically taking the average of ur two x terms.
you do the same with the y terms.
midpoint is : ((2 + 4)/2 , (4 + 6)/2) = (6/2 , 10,2) = (3,5)
So, IE is not parallel to GH.
