The second one and the fourth one.
Step-by-step explanation:
As the problem states, it takes 166.5 gallons of water in 3 mins. Since it states it is a proportional relationship, we know that 166.5/3 is the number of gallons pumped in 1 minute. We can write this as g(the number of gallons) = 166.5/3 * m(the number of minutes) ! In additon, 166.5/3 is equivalent to 55.5, which gives us the second and the fourth equation correct!
Answer:
w = 13, 11, 12
Step-by-step explanation:
3 (15 - w)
3 (15 - 13)
3 (2)
w = 6
___
3 (15 - x)
3 (15 - 11)
3 (4)
w = 12
___
3 (15 - x)
3 (15 - 12)
3 (3)
w = 9
(hope this helps!)
The second one is the true statement
Answer:
16x^4+32x^3+24x^2+8x+1
