The upper quartile is, Q1, is 45. The lower quartile, Q2, is 85. The interquartile range is 40. I hope this helps!
MN + NP = MP
6x - 7 + 2x + 3 = 60
8x - 4 = 60
8x = 64
x = 8
MN = 6(8) - 7 = 56 - 7 = 49
answer
x = 8
MN = 49
True, Integers mean "whole", and it cannot be a fraction or decimal

3x - 9y - 5x - 7y
Combine like terms
( 3x + - 5x ) + ( - 9y + - 7y )
= - 2x - 16y
When adding fractions you need to get common denominators then you multiply too times bottom and then boom add and there you go
