Answer:
y =14
11x = 11*3.5 =38.5
3x+2y = 11x = 38.5
Step-by-step explanation:
The perimeter of a triangle is the sum of all three sides
3x+2y + 11x+y = 91
Combine like terms
14x +3y = 91
The lines mean the sides are equal
3x+2y = 11x
Simplify
Subtract 3x from each side
3x-3x+2y = 11x-3x
2y = 8x
Divide by 2
2y/2 = 8x/2
y = 4x
Substitute 4x in the first equation every time you see y
14x +3y = 91
14x +3(4x) = 91
14x+12x=91
26x = 91
Divide by 26
26x/26 =91/26
x = 3.5
Now we can find y
y = 4x
y = 4(3.5)
y = 14
We know x and y we can find the length of each of the sides
y =14
11x = 11*3.5 =38.5
3x+2y = 11x = 38.5

Answer:
Sam will get £30 while Bethan will get £24.
Step-by-step explanation:
The total ratio shared by Sam and Bethan is 5+4 = 9
1 share ratio is the total amount involved divided by the total ratio
That is, £54/9 = £6
if 1 share ratio is £6,
Sam with 5 share ratio will get £6*5 = £30
while Bethan with ratio 4 wiill get £6*4 = £24
Numbers: 1, 2, 3, 4, 5, 6, 7, 8, 9
probability that <span>both numbers are greater than 6 if the same number can be chosen twice.
3</span>² / 9² = 9/81 or 1/9
<span>the probability that both numbers are less than 7 if the same number can be chosen twice
6</span>² / 9² = 36/81 or 4/9
<span>the probability that both numbers are odd numbers less than 6 if the same numbers cannot be chosen twice
3/9 * 2/8 = 6/72 or 1/12
</span><span>the probability that both numbers are even numbers if the same numbers cannot be chosen twice
4/9 * 3/9 = 12/81 or 4/27</span>
