Hi there! :)

Answer:

x=7

*The answer must have a positive sign.*

Step-by-step explanation:

<h2>Lesson: Addition/Subtraction/Multiplication/and Division property of equality</h2>

First, you switch sides of an equation.

$x+5=12$

Then, you subtract by 5 from both sides of an equation.

$x+5-5=12-5$

You subtract by the numbers from left to right.

$12-5=7$

Final answer is x=7

I hope this helps you!

Have a nice day! :)

Answer:

Step-by-step explanation:

4y - 2(5 - y + 4) = 4y - 2(9 - y)

= 4y + 9*(-2) - y *(-2)

= 4y - 18 + 2y {Combine like terms 4y and 2y}

= 6y - 18

6y - 18 = 6*y - 6*3

= 6(y - 3)

6y- 18 = 2 *3y - 2*9

= 2(3y -9)

2(3y - 9) and 6(y- 3 ) are equivalent to 4y - 2(5- y +4)

Others are not equivalent

Circle assignment! THANKS so much its worth so much of my grade

kogti [31]

Answer:

1. B) Figure B.

2. C) Figure C.

3. D) Figure D.

4. C) Figure C.

Step-by-step explanation:

Given: Radius of Circle A= 4

Radius of Circle B= 5

Radius of circle C= 6

Radius of circle D= 7

Now, finding circumference and area of all the circle.

We know, circumference of circle= $2\pi r$

Area of circle= $\pi r^{2}$

Where, r= radius of circle and π = 3.14

First, solving for figure A

Circumference= $2\times 3.14\times 4= 25.12\ cm$

Area= $3.14\times 4^{2} = 50.24\ cm^{2}$

Solving for Figure B

Circumference= $2\times 3.14\times 6= 31.4\ cm$

Area= $3.14\times 5^{2} = 78.5\ cm^{2}$

Solving for Figure C

Circumference= $2\times 3.14\times 6= 37.68\ cm$

Area= $3.14\times 6^{2} = 113.04\ cm^{2}$

Solving for Figure D

Circumference= $2\times 3.14\times 7= 43.96\ cm$

Area= $3.14\times 7^{2} = 153.86\ cm^{2}$

∴ 1. Answer is Figure B.

2. Answer is figure C.

3. Answer is Figure D

4. Answer is Figure C.
