I made 12 dog treats using 1 cup of peanut butter. If I want to make 36 dog treats, how much peanut butter will I need? Write a

MaRussiya [10]

Answer:

You will need 3 cups peanut butter to make 36 dogs treats.

Peanut butter Cup : The dog treats made = 1: 12

Step-by-step explanation:

12 dog treats = 1 cup

So, by UNITARY METHOD

1 dog treat = (1/12) cup

So, 36 dog treats = 36 x (1/12) cup = 3 cups

So, you will need 3 cups peanut butter to make 36 dogs treats.

If 1 cup = 12 Dog Treats

then 1 x 3 cup = 12 x 3 dog treats

or, 3 Cups = 36 dog treats

The ratio of the Peanut butter cup : The dog treats made = 1: 12

Solve x

Step-by-step explanation:

$x^{2} - 4x - 7 = 0$

First, let's move the $7$ to the right-hand side so we can determine what constant we'll need on the left-hand side to complete the square:

$x^{2} - 4x = 7$

From here, since the coefficient of the $x$ term is $-4$ , we know the square will be $(x - 2)$ (since $-2$ it's half of $-4$ ).

To complete this square, we will need to add $(-2)^{2}$ to both sides of the equation:

$x^{2} - 4x + (-2)^2 = 7 + ^{-2}$

$x^{2} - 4x + 4 = 7 + 4$

$(x - 2)^{2} = 11$

Now we can take the square root of both sides to figure out the solutions to $x$ :

$x - 2 = \pm \sqrt{11}$

$x = 2 \pm \sqrt{11}$
