Answer:
16x -12y = 4
15x +12y = 27
Step-by-step explanation:
4x-3y = 1
5x+4y=9
Multiply the first equation by 4
16x -12y = 4
Multiply the second equation by 3
15x +12y = 27
We add all these mixed numbers together:
1 1/2 + 2 3/4 + 2 1/3
It will be easier to convert the mixed numbers into improper fractions:
3/2 + 11/4 + 7/3
Now we have to find the common denominator which is 12:
18/12 + 33/12 + 28/12 = 79/12 = 6 7/12
The answer is 6 7/12 hours.

Answer:
The correct answer is £449.20 rounded upto 2 DP.
Step-by-step explanation:
Brian pays £465.98 a year on his car insurance.
The insurance company reduces the price by 3.6%.
The amount reduced by the insurance company is 3.6% of 465.98 = £16.77528.
Price the insurance company charges now is given by subtracting the previous cost with the reduction amount.
Thus the insurance cost now = £ (465.98 - 16.77528) = £449.20472 ≈ £449.20.
Thus the reduced insurance cost Brian has to pay now is £449.20 rounded to 2DP.
