Answer:
Kameron has 5 quarters in his wallet
Step-by-step explanation:
Let
x----> the number of nickels
y----> the number of quarters
remember that
1 nickel=$0.05
1 quarter=$0.25
we know that
x=3y -----> equation A
0.05x+0.25y=2
Multiply by 100 both sides
5x+25y=200
Simplify
x+5y=40 -----> equation B
Substitute equation A in equation B
(3y)+5y=40
8y=40
y=5 quarters
x=3(5)=15 nickels

C = -D - B
There's nothing more you can say about it besides exactly
what you have already said, until you know the value of 't'.
For num 4 the answer to six is 22 the reason is this formula so write this down for n aswell
n(n+1)/2+1 the example could be as we know for 1 cut we always will have 2 slices so 1(1+1)/2+1 is 2 and for 6 cuts 6(6+1)/2+1 is 22 therefore the answer to 6 cuts is 22 and to n cuts is the formula n(n+1)/2+1
