The perimeter of a triangle is:
P = a + b + c
We are given that:
b = a + 3
c = 2 a – 3
Therefore:
68 = a + a + 3 + 2 a – 3
68 = 4 a
a = 17
and,
b = a + 3 = 20
<span>c = 2a – 3 = 31</span>
If 16 friends share 4 cupcakes, and each friend gets 4 pieces, you would need to cut each cupcake in 16th's to result in 64 pieces; 64/4 = 16
145 Ib= 65.7709kg
you can find the answer on google also they have a calculator for that if u have anymore questions like this just type in 145 Ib=__kg and it will pop up
I think boys =18
girls=12
boys :x
girls:y
student:z
the number of group for the boys :n
the numberof group for the girls :m
so x=(3/5)*z
y=(2/5)* z
x/y=3/2
3y-2x=0
(1/10)*z*n=(3/5) *z
so n=6
(1/5)*z*m=(2/5)* z
put x=(1/10)*z*6
y=(1/5)*z*2
into 3y-2x=0 and z=30
z=30 so x=(1/10)*30*6=18
y=(1/5)*30*2=12
I think the answer is 51. Hope this helps!
