Use Algebra Calculator: Math Papa. Really super helpful! I use it all the time for my math homework and it is literally never wrong! I hope this helps! Have a great day!!
x = 10, y = 40
Given the 2 equations
y = 4x → (1)
2y + 2.5x = 105 → (2)
Substitute y = 4x into (2)
2(4x) + 2.5x = 105, that is
8x + 2.5x = 105
10.5x = 105 ( divide both sides by 10.5 )
x = 10
Substitute x = 10 into (1)
y = 4x = 4 × 10 = 40
836
4 times 19 times 11
100 million
We just subsitue 3 for x and -4 for y, so we get
So
AP = 10
According to secant-secant theorem
(PB)(AP)=(PD)(PC)
6(AP) = (5)(12)
AP = 60/6
