The table shows the solution to the equation |2x − 5| − 2 = 3:

1 answer:

5 0

First add 2 to both sides, next add 2 + 3 to get 5, next break down the equation into two problems which would be 2x - 5 = 5 and -(2x - 5) = 5, NOT 2x - 5 = -5, so this is the FIRST incorrect step, while step 4 is incorrect because its suppose to be 2x = 5 not 10, that's the second step, not first so answer is:

Answer: A) Step 3.

Answer:

x=17

Hope it helps;)

Step-by-step explanation:

Subtract 8 from both sides of the equation

-x+8=9

-x+8-8=9-8

Simplify

Subtract the numbers

x= -17

Divide both sides of the equation by the same term

x= 17

-x/-1= -17/-1

Simplify

Cancel terms that are both in the numerator and denominator

Divide the numbers

x = 17

The third side is = 4

This is a perfect square. Also, using the Pythagorean theorem you can find the third side

3squared + xsquared = 5 squared
9 + xsquared = 25
xsquared = 16
sqrt of 16 = 4

Brainliest if you provide a valid explanation and answer!

Hoochie [10]

Answer:

11cm = diameter.

c=circumference

d=diameter

π=3.14

r=half of diameter

34.56

C=2πr

d=2r

Solving for d (diameter)

d=C

π=34.56

π≈11.00079cm

rounded = 11cm!
