Step-by-step explanation:

Diameter of circle = 14 inches

Radius = 7 inches

$area \: of \: circle = \pi {r}^{2} \\ = \frac{22}{7} \times {7}^{2} \\ = 22 \times 7 \\ = 154 \: {inches}^{2}$

Hence, area of circle = 154 square inches.

Label Them to Least to greatest; | = absolute value ......-2 1/4 , 3/4 ,|-2 1/4| , | 1 1/4| ,| -1 3/4| ,-1 1/4

<h3><u>Label Them to Least to greatest</u></h3>

-2.25, -1.25, 0.75, 1.25, 1.75, 2.25

<em><u>Solution:</u></em>

We have to order from least to greatest

Given are:

$-2\frac{1}{4}\\\\\frac{3}{4}\\\\|-2\frac{1}{4}|\\\\|1\frac{1}{4}|\\\\|-1\frac{3}{4}|\\\\-1\frac{1}{4}$

Absolute value means magnitude of a quantity without regard to sign

Therefore, convert them into decimal for easier comparisons

$\rightarrow -2\frac{1}{4} = -\frac{4 \times 2+1}{4} = -\frac{9}{4} = -2.25$

$\rightarrow \frac{3}{4} = 0.75$

$\rightarrow |-2\frac{1}{4}| = 2\frac{1}{4} = \frac{9}{4} = 2.25$

$\rightarrow |1\frac{1}{4}| = 1\frac{1}{4} = \frac{5}{4} = 1.25$

$\rightarrow |-1\frac{3}{4}| = 1\frac{3}{4} = \frac{7}{4} = 1.75$

$\rightarrow -1 \frac{1}{4} = -\frac{5}{4} = -1.25$

Arrange them from least to greatest

-2.25 is the most negative and so it is the smallest

-2.25, -1.25, 0.75, 1.25, 1.75, 2.25

Thus the ascending order is found

Since you can't subtract 6/12 from 3/12 rename 7 3/12 as 6 15/12. Why?

Bingel [31]

Because 3 is not large enough to subtract 6 from.
Let's look at it this way:
I like to think of mixed number as pizzas and pizza slices. in the mixed number 7&3/12, 7 represent 7 whole pizzas, the denominator 12 represents the number of slices each pizza can be cut into, and the numerator 3 represents three slices (in the 8th pizza). when you subtract 6/12 from 7 and 3/12, since 6 is the numerator which represents slices, you are trying to take away 6 slices. but you only have 3 slices, that is not enough, so you cut one of the whole pizzas into 12 slices, now you have 6 whole pizza left and 15 slices, now you can give away 6 slices from the 15 slices.
I hope this makes sense to you.
you use this method to do addition and subtraction. when you do mixed number multiplication and division, you have to cut all the wholes into slices. well, that's a topic for another day.

Drag each tile to the correct location on the algebraic problem. Not all tiles will be used,

Tema [17]

Answer/Step-by-step explanation:

4x - 7 = -2x + 12 (Given)

Add 2x to both sides

4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)

6x - 7 = 12 (Simplication)

Add 7 to both sides

6x - 7 + 7 = 12 + 7 (Addition property of equality)

6x = 19 (Simplification)
