Find the value of x. One

Mathematics
1 answer:
Feliz [49]3 years ago
5 0

Answer:

x=24

Step-by-step explanation:

By the vertical angles theorem all vertical angles are congruent. So 4x-10 is equal to 86.

4x-10=86 ------> Add 10 to both sides

4x=96 --------> Divide 4 by both sides

x=24

What is the answer to this equation: 7.4 - 9 - 2r =18
lorasvet [3.4K]

We can get the answer to this equation by solving for the variable (r).


7.4 - 9 - 2r = 18


We want to get r on one side, so we want to push everything else to the other side.


-2r = 18 - 7.4 + 9


-2r = 19.6


2r = -19.6


r = -9.8
