There are 28 students in a math class and 22 of the students passed a recent test what percentage pass this test round to the tenths place

78.5%

Step-by-step explanation:

percentage = (amount/total) x 100

amount that passed the test = 22

total amount of students = 28

percentage that passed the test

= (22/28) x 100

= 78.5

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

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.
