Aroller coaster can accommodate 346 rider in 20 minutes. how many riders could ride in 90 minutes?

1557 people

Step-by-step explanation:

If 346 can ride a roller coaster in 20  minutes then just do

346 times 4

which would equal 1384

then you do 1384 plus 173 (which would be half of 346)

Which equals 1557

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

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.
