Factor −6 out of −18a−30

fgiga [73]

Remark

This is like using the distributive principle only you are going backwards. Instead of trying to remove brackets, you are trying to create them.

Solution

Since you want to take - 6 outside the brackets you should divide both terms by - 6

- 18a: - 18a/- 6 = 3a which is left inside the brackets.

-30: - 30/-6 = 5

- 6(3a + 5)

Answer

-6(3a + 5)

How to solve 2X^2+Y^2 = X^2-Y^2

arlik [135]

$2x^2+y^2 = x^2-y^2\\\\
2x^2 - x^2 + y^2 + y^2 = 0\\\\
x^2 + 2y^2=0\\\\
x^2 = 0~~~\Longrightarrow~~~\boxed{x=0}\\\\
2y^2 = 0~~~\Longrightarrow~~~y^2 = 0~~~\Longrightarrow~~~\boxed{y=0}\\\\

You are making juice from concentrate. The directions on the packaging say to mix

mel-nik [20]

Answer:

25 can.

Step-by-step explanation:

Here is the complete question: You are making juice from concentrate. The directions on the packaging say to mix 1 can of juice with 3 cans of water to make orange juice. How many 12 fluid ounces cans of the concentrate are required to prepare 200 6-ounce servings of orange juice?

Given: Ratio to make juice with concentrate:water is 1:3.

As required we need to prepare 200 6 ounce serving of Orange juice.

∴ $200\times 6= 1200\ ounce$

Let there be x ounce of concentrate and 3x ounce of water to make 1200 ounce of orange juice.

Now, $x+3x= 1200$

∴ x= 300 ounce

Next, lets find out how many cans of 12 ounce is required.

$\frac{300}{12} = 25\ cans$

∴ 25 cans is required to make 1200 ounce of orange juice.
