How do you divide 1 quart into 3 containers ?

Answers

The US customary system is a horrible, horrible thing.
We want to divide this quart into 3 containers using customary units.
Let's look at smaller customary units and see how that does us.

1 quart = 2 pints, so
1/3 quart = 2/3 pint.
We still don't have whole numbers, so let's keep going.

1 pint = 2 cups, so
2/3 pint = 4/3 cup.
Since we have a whole cup now, we leave that and keep going with the 1/3 c.

1 cup = 8 fluid ounces, so
1/3 cup = 8/3 fl. oz.
8/3 fl. oz. = 2 fl. oz. + 2/3 fl. oz.
Can you see where this is going?

1 fluid ounce = 2 tablespoons, so
2/3 fl. oz. = 4/3 Tbsp.
4/3 Tbsp. = 1 Tbsp. + 1/3 Tbsp.

1 tablespoon = 3 teaspoons, so
1/3 Tbsp. = 1 teaspoon! YES!

So our answer is 1 cup, 2 fluid ounces, 1 tablespoon, and 1 teaspoon.
(if you wanted that all in one unit, it'd have to be 64 tsp.)

(x + 5) ( x -3 ) using what algebraic identity?​

Answers

Answer:

Step-by-step explanation:

hello :

(x + 5) ( x -3 )= x²-3x+5x-15

(x + 5) ( x -3 )= x²+2x-15

Answer:

x² +2x - 15

Step-by-step explanation:

(x + 5) ( x - 3 ) =

= x² + 5x - 3x - 15

= x² +2x - 15

Find the value of B - A if the graph of Ax + By = 3 passes through the point (-7, 2), and is parallel to the graph x + 3y = -5. Pls help ASAP btw, the answer isn’t -12/19 or 12/19

Answers

Answer:

B - A = -6

Step-by-step explanation:

Given

Point: (-7,2)

x + 3y = -5

Required

Find B- - A in Ax + By = 3

To start with; we need to calculate the slope of x + 3y = -5

x + 3y = -5

Subtract x from both sides

x - x + 3y = -5 - x

3y = -5 - x

Divide both sides by 3

(3y)/(3) = -(5)/(3) - (x)/(3)

y = -(5)/(3) - (x)/(3)

The slope of the line is the coefficient of x

Slope = - (1)/(3)

The question says line Ax + By = 3 is parallel to line x + 3y = -5; This means that they have the same slope of - (1)/(3)

Having calculated the slope, next is to calculate the equation of the line using the following formula;

m = (y - y_1)/(x - x_1)

Where m is the slope; m = - (1)/(3); (x_1, y_1) = (-7,2)

Substitute these values in the formula above; the formula becomes

-(1)/(3) = (y - 2)/(x - -7)

-(1)/(3) = (y - 2)/(x +7)

Cross Multiply

-1(x+7) = 3(y-2)

Open brackets

-x - 7 = 3y - 6

Add x to both sides

x - x - 7 = 3y - 6 + x

-7 = 3y - 6 +x

Add 6 to both sides

-7 + 6 = 3y -6 + 6 + x

-1 = 3y + x

Multipby both sides by -3

-3(-1) = -3(3y + x)

3 = -9y - 3x

-9y - 3x = 3

-3x - 9y = 3

Comparing the above to Ax + By = 3

Ax = -3x\nA = -3

By = -9y\nB = -9

B - A = -9 - (-3)

B - A = -9 + 3

B - A = -6

What is 9/10 take away 4/10

Answers

(9)/(10) - (4)/(10) = (9-4)/(10) =\boxed{\bf{(5)/(10)=(1)/(2)}}
9/10 - 4/10 is just 9-4=6 and put that over 10 so you get 6/10.  If you have to reduce just do it by 2 on both.  6/2= 3 and 10/2=5 so 2/5.
