  • x = 13.5
  • y = 3.5

Step-by-step explanation:

  • Solving for x

7x + 30 = 11x - 24

30 + 24 = 11 - 7x

54 = 4x

54/4 = x

27/2 = x

<u>13.5 = </u><u>x</u>

  • Solving for y

5y + 38 = 17y - 4

38 + 4 = 17y - 5y

42 = 12y

42/12 = y

21/6 = y

7/2 = y

<u>3.5 = y</u>

How many cubic feet are in 3 cubic yards?
dimaraw [331]
For every cubic yard, it equals to 27 cubic feet.

So, could have this fraction \frac{27 feet^3}{1 yards^3}
And we want to convert 3 cubic yards into cubic feet.

We can express 3 cubic yards as \frac{3 yards^3}{1}

Now multiply the \frac{3 yards^3}{1} fraction by the second fraction or the reciprocal of the second fraction to cancel out the yards^3 units.

\frac{3 yards^3}{1} * \frac{27 feet^3}{1 yards^2} =  \frac{81 feet^3}{1}

So, 3 cubic yards to equal to 81 cubic feet.

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
