Becca graphs the equations y = –3(x – 1) and y = x – 5 to solve the equation –3(x – 1) = x – 5. her graph is shown below.

we have

------> equation A

------> equation B

we know that

The intersection point both graphs is the solution of the system of linear equations

Using a graphing tool

see the attached figure

the solution is the point  

Alternative Method

Becca equate equation A and equation B

Eliminate the parenthesis left side

Find the value of y

Substitute the value of x in the equation A or B

the solution is the point  

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
