Brad have 19 quarters and 27 nickels.
Step-by-step explanation:
Given,
Total worth of nickels and quarters = $6.10 = 6.10*100 = 610 cents
One quarter = 25 cents
One nickel = 5 cents
Let,
x represent the number of quarters.
y represent the number of nickels.
According to given statement;
25x+5y=610 Eqn 1
y = x+8 Eqn 2
Putting value of y from Eqn 1 in Eqn 2

Dividing both sides by 30

Putting x=19 in Eqn 2

Brad have 19 quarters and 27 nickels.

1/3 chances the bubblegum is blue. To solve this problem you add all of the bubblegum together so 25+20+15 to get 60 then express it as a fraction to show only the blue pieces which would be 20/60 and you can simplify it to 1/3 or 33.33%
The vertex (5,39)
5 is the value of x. 39 is the value of y. y is the cost function of the minimum value in dollars.
(5,39) vertex means that <span>Buying five of each type of plant costs $39, which is the lowest possible cost.</span>
Common difference is +6 and I think nth term is 5 (pretty sure it's always the first term) and the second one im not so sure about I'm sorry.
