Answer: 17.1
Step-by-step explanation:
If she averages 3.42 kills per game, she should average that for each of the 5 games. You need to multiply 3.42 times 5 for the total of 5 games.

Answer:

Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 5
// Plug this in for variable y in equation [1]
[1] x - 2•(-x +5) = 8
[1] 3x = 18
// Solve equation [1] for the variable x
[1] 3x = 18
[1] x = 6
// By now we know this much :
x = 6
y = -x+5
// Use the x value to solve for y
y = -(6)+5 = -1
Solution :

Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
