A radio station did a survey to determine what kind of music to play by
taking a sample of middle school, high school, and college students. They
were asked which of three different types of music they prefer on the
radio: hip-hop, alternative, or classic rock. The results are summarized in
the table below. What percentage of high school students prefer
alternative?
(A) 44
(B) 56
(C) 85
(D) 28

x= 149. 24+7=31. 180-31=149

your welcome

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

can someone me: the midsegment through the legs of an isosceles triangle is 4 in. find the sides of the triangle if its perimeter is 20 in. ,   and point g is the centroid of the right △abc with hypotenuse ab=18 in. find cg.
