Answer:

x = 9

x = 3

Step-by-step explanation:

find the roots of x² - 6x - 27 = 0

by factorization (or use any of your favorite methods for solving quadratic equations):

x² - 6x - 27 = 0

(x-9)(x+3) = 0

Hence,

(x-9) = 0 --------> x = 9

(x+3) = 0 --------> x = -3

At Scobee Middle School, 35% of the seventh graders ride the bus to school. If there are 320 seventh graders, how many 7th grade

anzhelika [568]

Answer: 112 7th graders ride the bus .

Step-by-step explanation:

Given: The proportion of 7th graders ride the bus to school= 35% = 0.35 [to remove % we divide number by 100]

If there are 320 seventh graders, then the number of 7th graders ride the bus = 320 x (proportion of 7th graders ride the bus to school)

$0.35 \times 320$

$= 112$

Hence, 112 7th graders ride the bus .

Alexxx [7]

Step-by-step explanation:

1) -5x<35

we divide both sides by 5

-5x/5<35/5

-x<7

we divide both sides by-1 to remove the negative sign

-x/-1<7/-1

x<7/-1

2) 2x>-42

we divide both sides by 2

2x/2>-42/2

x>-21

3) x/3≤-7

we multiply by 3 and we cancel 3

3(x/3)≤3(-7) we cancel the 3

x≤-21

4) x/-4≥-4

we do the same thing

x≥1
