Six teachers at Histogram High School are brand new teachers this year. These teachers represent 15% of the teachers at the school. How many teachers work at Histogram High School? SHOW WORK! A single answer is cool and all but thats not really gonna cut it. Even a simply division problem is fine just show me how you got your answer.

40

Step-by-step explanation:

6=15%

?=100%

100÷15=6.6666666666666666666666666666667

6x6.6666666666666666666666666666667=40

40 teachers at the high school

Step-by-step explanation:

6/15%=Y/100%

or:

15y = 6*100

15y = 600

y = 600/100 = 40

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.
