question 4(multiple choice worth 4 points)

(07.01)colton solved an equation incorrectly, as shown below:

step 1: x − 13 = 26
step 2: x = 26 − 13
step 3: x = 39

which statement best explains why step 2 is incorrect in colton’s solution?
he did not subtract 13 from 26.
he did not multiply 26 by 13.
he did not add 13 to 26.
he did not divide 26 by 13.

Hello there! :)

1. B. 8. and x=8

*The answer must have a positive sign.*

2. D. Infinitely many.

3. D. -1 and y=-1

*The answer must have a negative sign.*

4. C. He didn't add 13 to 26.

5. B. 4 and y=4

*The answer must have a positive sign.*

Step-by-step explanation:

1. First, you divide by 5 from both sides of an equation.

Then, simplify.

→

_______________________________________________

2.  4x=4x both sides are equal and it's true.

________________________________________________

3. First, switch sides of an equation.

Then, you subtract by 9 from both sides of an equation.

Simplify and solve.

→

________________________________________________________

4. First, add by 13 from both sides of an equation.

Then simplify and solve.

and

_______________________________________________________

5. First, subtract by 9 from both sides of an equation.

Then simplify and solve.

Hope this helps!

Thanks!

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

32
