I switched the x and y so it’s easier to see. The answer is (x-1)/(23).
Answer:
5r + 2p + 6
Step-by-step explanation:
= 4r + 9 + r + 2p - 3
= 4r + r + 2p + 9 - 3
= 5r + 2p + 6
Answer:
D
Step-by-step explanation:
Either try all the numbers and see which ones work or do the following.
Times both sides by 2x-5.
3=x(2x-5)=2x^2-5x
Rearrange and solve the quadratic. I will factorise.
2x^2-5x-3=0
(2x+1)(x-3)=0
so x = -1/2 or 3
Say x=5.764---
Then 1000x=5764.764---
Then 1000x-x = 5759
So 999x = 5759
So x=5759/999
I don't see how b can be 0 in this case... what does that mean? You would never divide by 0 and live to tell about it, right?
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
