Answer:
Step-by-step explanation: so first you got to distribute the on both sides so like the 2 and the ten from there you just eliminate and do it like normal. I’m sorry I’m bad at at explaining it but I hoped it helped some how :)
Answer:
the probability is 2/5
Step-by-step explanation:
just put 8 over 20 and simplify it
Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.
In fact, if the daughter weights 
pound, the mother weights 
pounds, and the total weight is 
.
We know that this total is 185 pounds, so we have
So, the daughter weights 37 pounds.
Answer:
10
Step-by-step explanation:
if you divide 100 divided by 10 equal 10 and that's the correct answer for how I got 10
Answer:
A square has 4 sides with equal length.
So the perimeter of a square is equal to 4 times the length of one side.
Now, suppose that we know that the length of one side of the garden is x.
Then the total length of the fence that surrounds the square is:
L = 4*x.
Now let's define proportional quantities:
x and y are proportional quantities if:
x = k*y
where k is a constant of proportionality.
In the case of our problem, we have a relation between L (total length of the fence) and x (length of one side of the garden)
L = 4*x
This is a proportional relation, and 4 is the constant of proportionality.
