Your answer is 27 I pretty sure sorry if it’s wrong.
Let's evaluate left side first.
There are 4 -5's and 5 -3's
So that's 4(-5) + 5(-3) = -35
So now our equation is -35 = -5x
Now divide both sides by -5:
-35 / -5 = x
7 = x
So the missing number would be 7 to make this equation true.
Final answer: 7
Hope this helps.
The answer is 460.8 because if u multiply them then that's the answer
Radii is defined as the line joining the centre of the circle to a point on the circumference
as there are infinite points on a circle
therefore there are infinite number of radii and hence there is no fixed number.
