Answer:

  x = -5

Step-by-step explanation:

Collect terms:

  -3x -3 = 12

Divide by -3:

  x +1 = -4

Subtract 1:

  x = -5

_____

The more conventional solution method would be to save the division by -3 until the end. The second step could be to add 3 to both sides. Then you would have ...

  -3x = 15

and dividing by -3 would give the same answer.

Answer:

x = - 5

Step-by-step explanation:

3x - 3 - 6x = 12

group like terms

3x - 6x - 3 = 12

add similar elements

- 3x - 3 = 12

add 3 to both sides

- 3x - 3 + 3 = 12 + 3

simplify

- 3x = 15

divide both sides by 3

- 3x / 5 = 15 / - 3

simplify

x = - 5

You have some tigers. You have some cages. If you put one tiger in each cage, your will have one tiger left over. If you put two
vredina [299]

Answer:

The correct answer is there are 3 cages and 4 tigers.

Step-by-step explanation:

Let there be x cages and y tigers.

According to the first condition, if we put one tiger in each cage, one tiger is left over.

∴ y - x =1

According to the second condition, if we put two tigers in each cage, one cage is left over.

∴ x - \frac{y}{2} =1

⇒ 2x - y = 2

Therefore adding both the equations we get,

y - x + 2x - y = 2 + 1

⇒ x = 3

⇒ y = 4

Therefore there are 4 tigers and 3 cages.

If a baker doubles a recipe that calls for 6-2/3 cups of flour. How many cups will be needed in all?
nadya68 [22]
Hey there!

The easiest way I could think to do this is by converting your mixed number to an improper fraction and multiplying the fraction by 2, or 2 over 1. 

6 \frac{2}{3}  = 6*3+2 =  \frac{20}{3}

\frac{20}{3} *  \frac{2}{1}

To multiply fractions, you can just multiply the numerators and denominators and simplify, if applicable. 

\frac{20}{3} * \frac{2}{1} = \frac{40}{3}

Since you can't simplify this fraction in its improper form, just convert it back into a mixed number. 

\frac{40}{3} = 13 \frac{1}{3}

So, your answer will be 13 \frac{1}{3}. 

Hope this helped you out! :-)
