Answer:
b= (Z-m-z)/(x)
Step-by-step explanation:
Z-m=z+bx
Z-m-z=bx [Transpose z of R.H.S to L.H.S] / [Substract z from L.H.S and R.H.S]
(Z-m-z)/(x)=b [Divide by x on both sides i.e, L.H.S and R.H.S]
b= (Z-m-z)/(x)
Hope this helps you.
Answer:
A
Step-by-step explanation:
15/x=75/100
15/x=3/4
times 4x both sides
4*15=3x
60=3x
divide both sides by 3
20=x
20 = 4 y
Y =5
