-4/6 times 2 is -8/12
x - 8/12= x + 2/12
0=10/12
0=5/6
but since 0 does not equal 5/6, this will be no solution
-2x^2 + 500x - 350
You need to plug in the equations for C(x) and R(x) into the equation P(x)= R(x) - C(x) and solve.
Answer: 20
Explanation: Alright, so basically you’re going to want to use PEMDAS (Parenthesis, Exponents, Multiplication/ Division, Addition/ Subtraction)
* just means multiply.. sooo the problem looks like this:
6x(12-7.5)-7
We’ll start at the parentheses :)
So (12-7.5) = 4.5
Now our problem looks like: 6x(4.5)-7
Following PEMDAS, the next thing to come up is multiplication! So we’re going to multiply 6 by 4.5 ...
6x4.5=27
After this our problem looks like: 27-7
So now it’s just simple math...
27-7= 20
A major arc is over 180°.. minor arcs are under 180°... I think this is right
Hope this helps
