Answer:
Seth has 21 nickels
Step-by-step explanation:
Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.
Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then
Solve this equation:
$81.75 because if DeShawn has 3 friends plus him that’s four people and 327 divided by 4 is 81.75

When you multiply each side of an equation by the same number,
you don't change the equation or its solution. If you want to get rid
of the decimals, you could multiply each side by 10. Then the
equation is
5x - 1 = -29
You should be able to solve that without help.
But I'm about to take your points, so here's
how to solve that equation:
</span><span><span>5x - 1 = -29
Add 1 to each side: 5x = -28
Divide each side by 5 : x = -28 / 5
Simplify the solution: x = -5 and 4/5 .
Again ... this is the same solution as the original equation
if we hadn't gotten rid of the decimals.

No, that line will not be the correct line of best fit for the data set
Step-by-step explanation:
A positive correlation relationship means that both variables move in the same direction.
This means when one variable increases the other one also increases or one variable decreases as the other one decrease.
If value of r is 0.2-0.39 it is considered to be weak. Values of r 0.6 and above to 1.0 are considered to be strong.
However,these are all arbitrary limits thus context of the results should be considered.
