Answer: B
Step-by-step explanation: A=πr2
The formula for calculating the area of a circle is A = πr2 where pi (π) equals 3.14 and the radius (r) is half the diameter.
You must times 5 by 5 because of exponents and then times it by pie
5 times 5 = 25
25 times pie is 78.5
250 - 5(x) = 50
250 (-250) - 5x = 50 (-250)
-5x = -200
-5x/-5 = -200/-5
x = 40

I agree with what that person told you. The expression -2(x+10) is equivalent to -2x-20
Multiply the outer -2 with the inner x to get -2 times x = -2x
Multiply the outer -2 with the inner term 10 to get -2 times 10 = -20
So overall, -2(x+10) = -2x-20

So that's how we're able to go from this

to this

The only thing that changes is the left side. The inequality sign will not flip. It only flips if we multiply both sides by a negative number.
so together the amount of people who chose beef should be 4/12 since you must find the greatest commen factor. Then you should add 4/12 and 24 im thinking and you would get 24.3333 but if your looking for a mix number it would be 24 3333/1000
hope this helps!
Answer: the lines are not parallel.
Explanation: if you isolate the x in 3x^2-4y=-1, the equation is y=3/4x^2+1/4
So, they are not parallel because the slope is not the same.
