Answer:
£30
Step-by-step explanation:
To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.
1 : 6 = 1 + 6 = 7 parts
Now divide the total amount of parts by the total amount of money shared
35 / 7 = 5
Now multiply the answer by the value that is appropriate.
In this case, they want you to work out how much Ali recieved.
Ali's value is 6
6 × 5 = £30
hope this helps :)
Answer:

Step-by-step explanation:
Step-by-step explanation:
Line2
Line 3
- 3x + 2y = 6
- 3x = -2y + 6
- x = -2/3y + 2
Line 4
- 1/4x + y = 2
- y = -1/4x + 2
Line 5
- 4x - 3y = -33
- 3y = 4x + 33
- y = 4/3x + 11
Questions
- 1. Yes. You need to isolate the variable to find and simplify.
- 2. To solve for x would require to multiply all terms by 4 to get rid of fraction
- 3. It wouldn't be easy because of the fraction. To make it easier would use multiples of 3 for x.
