Solve for y -72=8(y-3)
DaniilM [7]

Answer:

Step-by-step explanation:

y - 72 = 8(y - 3)

Distribute the 8 into (y - 3).

y - 72 = 8y - 24

Subtract 8y from both sides.

-7y - 72 = -24

Add 72 to both sides.

-7y = 48

Divide both sides by -7.

y = -48/7 or approxametly -6.9.

Proof:

y - 72 = 8(y - 3)

Substitute variable.

-48/7 - 72 = 8(-48/7 - 3)

Subtract.

-552/7 = 8(-69/7)

Multiply 8 by the inside term -69/7.

-552/7 = -552/7.

AB and CD intersect at point E if measure angle AED equals 6x-24 and measure angle CEB equals 4y+32 find the values of x and y s
Zolol [24]

The values of x and y such that AB is perpendicular to CD will be 19 and 14.5.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

AB and CD intersect at point E.

If measure angle AED equals 6x – 24 and measure angle CEB equals 4y + 32.

Then the values of x and y such that AB is perpendicular to CD will be

6x – 24 = 90

        6x = 114

          x = 19

Then we have

4y + 32 = 90

       4y = 58

         y = 14.5

More about the angled link is given below.
