5x + 10y = 360
y = 2x + 1
5x + 10*(2x + 1) = 360
5x + 20x + 10 = 360
25x = 350
x = 14
y = 2x + 1
y = 2*14 + 1
y = 29
Derek has 14 nickels and 29 dimes
5 - 10 x = 3
10 x = 5 - 3
10 x = 2
x = 10 : 5
x = 0.2
The rate is : 0.2 gallons / minute
5 - t * 0.2 = 0
t * 0.2 = 5
t = 5 : 0.2
t = 25 min
Answer: After 25 minutes the container will be empty.
Answer:
− x + 16y
Step-by-step explanation:
2x + 5y − 3x + 11y
= 2x + 5y + − 3x + 11y
Combine Like Terms:
= 2x + 5y + − 3x + 11y
= (2x + − 3x) + (5y + 11y)
= − x + 16y
