Answer:
Step-by-step explanation:
3x+y=2............(1)
4y=12-12x........(2)
Making y as subject in (1) and substitute in (2)
y = 2 - 3x......(3)
4(2 - 3x) = 12-12x
8 - 12x = 12 - 12x
12x - 12x = 12- 8
0 = 4
So no solution since variable cancelled out
The formula for conditional probablity states that
Since we know both numerator and denominator, we only need to plug in the values:
A cube has 6 sides.
A cube is all made up of squares.
So, we need to find the area of one cube and multiply that by 6.
Length * width= area
40*40= 1,600
Multiply that by 6.
1,600*6= 9600
Whatever the unit is after that: in, feet, cm, m, etc- put that after the number with ^2.
9,600 (the unit) ^2
I hope this helps!

Answer:
Step-by-step explanation:
In order to find an average you need to add all the numbers you have and then divide your sum by the amount of numbers you added.
195+52+206=432
432 divided by 3= 151
That is the answer, 151.
Answer:
3 : 7
Step-by-step explanation:
Let the radii be 3x, 7x.
Circumference = 2πr, where r = radius
Thus, ratio of circumference:
2 × π × 3x : 2 × π × 7x
= 3 : 7
( as 2, π and x get cancelled out)
