We are given with two equations and is asked to determine the solution of the system of linear equation. via elimination, we add the two equations to eliminate 3x, this means y should be equal to 9 and from the first equation, x should also be equal to 9, too

Answer:
Step-by-step explanation:
Consider a group of 1 dime and 2 nickels. The value of it is 0.20. The total value of all such groups is 3.20, so there must be ...
3.20/0.20 = 16 . . . . . groups of coins
That is, there are 16 dimes and 32 nickels.
Answer:
A
Step-by-step explanation:
Since only 30% of the population carries the gene, that would mean 70% doesn't carry it. Since you are using 10 digits for this experiment (0-9) this would mean that 0-2 would carry the gene (this equals 30%) and 3-9 would not (70%)
Answer:
14 miles
Step-by-step explanation:
Assuming each horse was only ridden once
then a total of 13 horses were ridden for a total of 182 miles
182 miles
/ 13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.
