Answer:

x = -5

Step-by-step explanation:

3x + 2(x - 9) = 8x + x + 2

~Distribute left side

3x + 2x - 18 = 8x + x + 2

~Combine like terms

5x - 18 = 9x + 2

~Add 18 to both sides

5x = 9x + 20

~Subtract 9x to both sides

-4x = 20

~Divide -4 to both sides

x = -5

Best of Luck!

Answer:

x = -5

Step-by-step explanation:

3x + 2(x - 9) = 8x + x + 2

-----Distribute left side-----

3x + 2x - 18 = 8x + x + 2

-----Combine like terms-----

5x - 18 = 9x + 2

-----Add 18 to both sides-----

5x = 9x + 20

-----Subtract 9x to both sides-----

-4x = 20

-----Divide -4 to both sides-----

x = -5    <---

Good luck on your exam! :D

loris [4]

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

= 1 : 2

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

True

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Orange juice : cranberry juice = 1 : 1

True

Determine the solution of the system. Show your work
Oxana [17]
First question:

1. Set equations equal to each other so 5x-9=2x+6
2. Put x's on one side so that 3x=15
3. Divide by 3 so that x=15
4. Substitute 15 in for x so that y=2(15)+6
5. Solve for y so that y=36
6. Thus the equations intersect at (15,36)

Second question:

1. Since for lines y=mx+b, and m=slope=3 you only need to write an equation with slope 3
2. y=3x+b, b can be any number
