3. 4y-3
because 1/3*12y - 1/3*9 = 4y - 3
Answer:
1.2%
Step-by-step explanation:
Solving our equation
r = 10.2 / ( 425 × 2 ) = 0.012
r = 0.012
converting r decimal to a percentage
R = 0.012 * 100 = 1.2%/year
The interest rate required to
accumulate simple interest of $ 10.20
from a principal of $ 425.00
over 2 years is 1.2% per year.
I think it’s y = 1x + 13.
Answer:
180 ahhahaahahhahaahahahhaa
1) let molly be y
And let Nancy be x
Since molly is twice as Nancy
So equation is 2x=y
(Twice Nancy age is equal to Molly’s age)
2)let molly be y
Let zanders age be z
Since zander is 6 yrs younger than molly
So 6yrs added to zanders age equals Molly’s age
Eq: z+6=y
3) ) molly’S age =y,Nancy age =x
Since molly is twice as Nancy
So 2x=y. (Nancy is 10 .....given )
2*10 = 20
Or
molly =y
zanders =z
Since zander is 6 yrs younger than molly
Eq: z+6=y ( zandra is 14 ...given )
14+6=20
If u wanna submit it to your teacher the do write in the exact same way as above
Plz mark me brainest:)
