The answer is 4. 3 busses would carry 180, so you gotta have that one extra bus. The question is set up to kind of throw you off but it's quite simple

AC = 64,<br> AB = 7x + 8, and<br> BC = 3x + 6,<br> Find BC.
iVinArrow [24]

Answer:

21

Step-by-step explanation:

  • AC = 64
  • AB = 7x + 8
  • BC = 3x + 6

<u>Since AC = AB + BC</u>

  • 7x + 8 + 3x + 6 = 64
  • 10x + 14 = 64
  • 10x = 50
  • x = 50/10
  • x = 5

------------------

BC = 3x + 6 = 3*5 + 6 = 21

Which of these systems of equations would be best solved using the subtraction​ method?
Lynna [10]

Answer:

Step-by-step explanation:

1. x+2y=6 or x=6-2y

3x-2y=2

3(6-2y)-2y=2

18-6y-2y=2

18-8y=2

-8y=-18+2

-8y=-16

y=-16/-8

y=2 ans.

x+2*2=6

x+4=6

x=6-4=2 ans.

Proof:

3*2-2*2=2

6-4=2

2=2

I leave the rest for you to practice with.

3. 4x+y=7

2x+5y=-1

 

5. 3x+2y=-2

6x-y=6

Solve the system using the elimination method. Show all your steps.

7. -3x+3y=3

3x+y=9 add.

---------------------------------

4y=12

y=12/4

y=3 ans.

3x+3=9

3x=9-3

3x=6

x=6/3

x=2 ans.

Proof:

-3*2+3*3=3

-6+9=3

3=3

I'll leave the rest for practice.

9. -5x+12y=20

x-2y=-6

11. 3x+2y=1

4x+ 6y= 7
