Answer:
The number of ways of selecting a combination of 8 marbles from a bag containing 20 marbles is 125970
Step-by-step explanation:
The number of selecting 8 marbles from a bag of 20 marbles
A combination gives the number of possible order or arrangement in a collection of k items selected from a set of n items
In the question, k = 8, and n = 20
Substituting the values of n and k in the above equation gives;
Therefore, the number of ways of selecting 8 marbles from a bag containing 20 marbles is given by the combination C₂₀, ₈ = 125970.
Since it says that T is the midpoint that means it equal divided the line. So,
X+3 must equal 4x
X+3 =4x
Subtract x on both sides
3=3x
Divide 3 on both sides
1=x
Plug in x into equation
4(1) =4
TU =4
Step-by-step explanation:
5x+y=-24x+3y=-2
-24x-5x=-29x
y=-29x+3y=-2
y+3y=4y
4y=-29x=-2
+2 +2
4y=-27
/4 /4
y=-6.75
