I hope this helps, I wrote the new equation each time you get a new number and where it should be placed
27 is 6
29 is 70
31 is 60
those are all of the answers.
Answer:
c
Step-by-step explanation:
20 cm is the answer good luck
(x + a)/(ax) = b/x
a= 2
b = 5
(x + 2) /(2x) = 5/x
cross multiply
x * (x+2) = (2x)*5
x^2 + 2x = 10x
x^2 - 8x = 0
x ( x -8) = 0
We get two solutions
x = 0, 8
the solution 0 is extraneous
the solution 8 is valid.
