Answer:
the answer is that 7x6 42 so you must divide by x to get the population
Step-by-step explanation:
Let's define,
X := Total minutes it takes to fill the plane (with fuel)
Then,
Solving it for X, we get
This means that the vehicle takes 1 h 2 min to fill the plane. If the fuelling finished at 10:35, it began at
9:33.
2/5 is equivalent to 0.4 or to 4/8 (for example).
Answer:
7 $5 bills, 32 nickels
Step-by-step explanation:
Ok, so to solve this, we need to make two separate equations. If we say that x is the number of nickels, and y is the number of 5 dollar bills, adding up to $36.60, we can make the equations 0.05x + 5y = 36.60, and x + y = 39. Using substitution, we can say 0.05x + 5(39-x) = 36.60. This simplifies to 195-4.95x = 36.6. We can then say 158.4 = 4.95x, and x = 32. This means we have 32 nickels. As there are 39 total coins and bills, that means there are 7 $5 bills, and 32 nickels.
Answer : (8,5)
Given
K(x) =
Now we plug in each point and check whether it satisfies our equation
(-64,12)
K(-64) = = 12 so this point lie on graph
(125,3)
K(125) = = 3 so this point lie on graph
(343,1)
K(343) = = 1 so this point lie on graph
(8,5)
K(8) = = 6 so this point does not lie on graph because we got 6 instead of 5
