Answer:
Completing the experiment a few more times and combining the results to the trails already done.
Answer:
Yes
Step-by-step explanation:
To see is (2, 6) is a system, we can plug it into the system to check if it gives us true statements:
6 = -2+8
6 = 6
6 = 5(2)-4
6 = 10-4
6 = 6
Both of the equations are true, therefore (2, 6) is a solution to this system.
Let p = number of pennies.
Let n = number of nickels.
We are given that n= 2p and the total value is $8.80.
We know that a penny = $0.01 and that a nickel = $0.05.
So $0.01p + $0.05n = $8.80.
Substitute 2p for n:
$0.01p + $0.05*2p = $8.80
$0.01p + $0.10p = $8.80
$0.11p = $8.80
p = 80
So n = 2p = 2*80 = 160
Thus there are 80 pennies ($0.8) and 160 nickels ($8.00). The value of all the coins is $8.80.
It’s 270 I believe good luck tho
