When Jaylen started high school, 1,430 students attended his school. On the day of his graduation, only 1,001 students attended his school. The number of students who attended Jaylen's school decreased by what percent?

The number of students decreased by 30%.

Step-by-step explanation:

Subtract 1430 from 1001, then find the absolute value.

Simplify 429/1430 by cancelling out 143.

Convert 3/10 into a percentage by multiplying it by 100.

The decrease of students was 30%.

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.
