Answer:
The value of y is 3 cm.
Step-by-step explanation:
Given,
Perimeter of triangle = 
Solution,
Lets redraw the triangle with nomenclature ABC, given in the attachment.
∴P(ΔABC) = 29 cm (P stands for perimeter)
Length of AB = 
Length of BC = 
Length of CA = 
Now, we all know that the perimeter of a triangle is sum of all the three sides of triangle.
P(ΔABC) = Length of AB+Length of BC+Length of CA
On substituting the values, we get;

Length of AB =
Length of BC =
Length of CA =
Hence the value of y is 3 cm.

Answer:
x=10
x=30
x=15.3
x=4
Step-by-step explanation:
1/2x+7=27
2x+7=27
2x=20
x=10
5=1x-25
30=1x
30=x
3x+9=54
3x=46
x=15.3
16=5x-4
20=5x
4=x
False, there are 5 possible outcomes
0
1
2
3
4
So the chance of each number is 1/5 or 20%
