Answer:
11
Step-by-step explanation:
4+5+7+14+17+12+18=77
Divide your total by the amount of numbers you have (7); 77/7
P is the principal amount, $5200.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 9....year(s) time periods.
So, t is 9....year time periods.
To find the simple interest, we multiply 5200 × 0.06 × 9 to get that:
The interest is: $2808.00
Answer:
1/3
Step-by-step explanation:
12/36 = 6/18 = 3/9 = 1/3
This becomes...........
[(y+7)/7y] x [(14y-5)/(3y^2+21y)]= [(y+7)/7y] x [(14y-5)/3y(y+7)]= [1/7y] x [(14y-5)/3y]= [(14y-5)/21y]
Remember, you can do anything to an equation as long as you do it to both sides
times 4 both sides because we hate fractions
3x+8=16x-4
minus 3x both sides
8=13x-4
add 4 both sides
12=13x
divide both sides by 13
12/13=x
x=12/13
