The appropriate choice is ...

... On Line 3, Brianna should have divided by 0.1 instead of subtracting 0.1.

_____

Had Brianna simplified her effort properly on line 4, she would have

... -0.1 +0.1x = -1.4

putting her essentially back where she started—with a 2-step equation.

Answer:

2 1/4

Step-by-step explanation:

1/3 divided by 1/6 is 2

3/4 plus 2 is 2 3/4

2 3/4 minus 6/12 is simplified to 2 9/12 minus 6/12, which is 2 3/12

2 3/12 is simplified to 2 1/4

Answer:

Number of students in vans =15 and bus =46

Step-by-step explanation:

use variables for the vans and buses

let x= vans and y=buses

Now solve the 2 equations simultaneously

remember to number your equations

6x+7y=412..........1

6x+9y=504.........2

make x the subject of one equation

and label it equation 3

6x=412—7y

$x = \frac{206}{3} - \frac{7y}{6} .............3$

subs 3 into 2

$6( \frac{206}{3} - \frac{7y}{6} ) + 9y = 504$

$412 - 7y + 9y = 504$

$- 7y + 9y = 504 - 412$

$2y = 92$

$y = 46...................4$

subs 4 into 1

$6x + 7(46) = 412$

$6x + 322 = 412$

$6x = 412 - 322$

$6x = 90$

$x = 15$

Therefore there are 15 students in each van and 46 students in each bus.
