Answer:
6.5 %
Step-by-step explanation:
The simple interest formula is
I = Prt
Data:
I = $1755
P = $3000
t = 9 yr
Calculation:
1755 = 3000 × r × 9
1755 = 27 000 r
Divide each side by 27 000
r = 1755/27 000 = 0.065 = 6.5 % APR
The annual percentage rate was 6.5 %.

b = 3a, a+b =2a+8 => a = 4, b = 12
Answer:
1: 1/192
Step-by-step explanation:
Answer:
writing this down numerically gives us
3x+2=5x-1
(x-the number)
to solve...
add 1 to each side
3x+3=5x
subtract 3x from each side
3=2x
2x=3
divide by 2 to get x
x=3/2
x=1.5
Let say the number = x
double my number and add eight, I get my number plus twelve
double x and add eight, I get x plus twelve
2x + 8 = x + 12 (subtract x from each side)
2x - x + 8 = 12
x + 8 = 12 (subtract 8 from each side)
x = 12 - 8
x = 4
Your number is 4
