The capacity of an elevator is 10 people or 1580 pounds. the capacity will be exceeded if 10 people have weights with a mean greater than 1580 divided by 10 equals 158 pounds. suppose the people have weights that are normally distributed with a mean of 167 lb and a standard deviation of 33 lb.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

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.
