What is the value of x
timama [110]

Answer:

The answer to your question is:  x = 27

Step-by-step explanation:

The are vertical angles, so they measure the same:

                          4x + 7 = 5(x - 4)

                          4x + 7 = 5x - 20                       Expanding

                          4x - 5x = -20 - 7                       Simplify like terms

                          -x = -27

                           x = 27

What is the answer for this math problem
trapecia [35]

7/8 is tricky to do on a computer, but I will say that it is 87.5 percent or 0.875.

Do you know how to do normal long division? This is like that. Just after the decimal point, drop a 0 down.

I hope this helps!
