Step-by-step explanation:

y - x = 3x +2

y=3x+x+2

y=4x+2.......(1)

2x + 2y = 14 - y

2x+2y+y=14

2x+3y=14.........(1)

substituting value of y in equation 1

2x+3(4x+2)=14

2x+12x+6=14.

14x=14-6

14x=8

x=8/14=4/7

substituting value of x in equation 1

y=4×4/7+2=30/7

x=4/7

y=30/7

sarah invests £9600 at a simple interest rate of 8% per year. Work out the value of the investment after 3 years
andre [41]

Answer:

the value of the investment after 3 years=  £11,904

Step-by-step explanation:

sarah invests £9600 at a simple interest rate of 8% per year

number of years = 3

Formula for simple interest

I = P*n* r

P is the initial amount invested= 9600

r is the rate of interest = 8% = 0.08

n = number of years = 3

Now we find interest using formula

I = 9600 * 0.08 * 3= 2304

Interest amount is 2,304

Now we add the interest with the initial amount to get the value of investment after 3 years

9600 + 2304= 11904
