Answer:
x = 13
Step-by-step explanation:
Combine like terms:
3/5x (x + 2 ) = x - 4
3/5x + 6/5 = x - 4
<u>-x -x</u>
-2/5x + 6/5 = -4
<u>- 6/5 -6/5</u>
-2/5x = -26/5
divide everything by -2/5
Your final answer should be 13.
You can double-check by substituting 13 into the original equations.
Answer:
26 m
Step-by-step explanation:
Find what length is needed for fencing by finding the perimeter of the land.
Use the perimeter formula, P = 2l + 2w
Plug in the length and width:
P = 2l + 2w
P = 2(8) + 2(5)
P = 16 + 10
= 26
So, the length of wire needed is 26 m
The expected number of female children in a family with three children is 1.5.
The correct option is B.
We have to determine
What is the expected number of female children in a family with three children?
<h3>Probability;</h3>
Probability is defined as the sum of all observations and the number of observations.
The expected value of female children= Probability of female children x Total number of children.
A child can be male or female, so there are 2 combinations, the favorable outcome is female.
The probability of female children = 1/2.
Therefore,
The expected number of female children in a family with three children is;
Hence, The expected number of female children in a family with three children is 1.5.
