Answer:
x = 2 and x = 1
Step-by-step explanation:
I think
Given:
a varies jointly as b and c.
a=6 when b=2 and a=3.
To find:
The variation constant and the equation of variation.
Solution:
a varies jointly as b and c.

...(i)
Where, k is the constant of proportionality.
a=6 when b=2 and a=3.




The value of k is 1.
Putting k=1 in (i), we get


Therefore, the variation constant is 1 and the equation of variation is
.
Answer:
0.03%
Step-by-step explanation:
Simple interes = PRT/100
Given
Interest = $590.00
Principal P = $8000
Time T = 285 days
Rate = ?
Since I = PRT/100
R = 100 x I /PT
= 100 x $590.00 /$8000 x 285
Multiply through
= 59000/2280000
= 0.03%
Y= 3x+3 is the correct answer:)
Easy.
2x + 3x
2x + 3x
2x ( 1 + 3x / 2x )
2x ( 1 + 1.5 )
2x ( 3 )
6x
or
2x ( 3 )
or
3x ( 2 )
That's it.
Hope helps ...........
