Trick question. See these negative signs? The left number is -9.375, and the right number is -0.8068181818181818... Notice that even though the right number looks like a smaller answer, it is closer to 0 on a number line, because it is negative. -71/88 is the correct answer.
The answer is A 5^11 I hope that's right
Answer:
14 quarters and 28 nickels
Step-by-step explanation:
System of Equations where x = number of quarters and y = number of nickels
(1) equation with value of each coin
0.25(x)+0.05(y) = 4.90
(2) total number of coins
x + y = 42
Solve system of equations using either substitution or elimination
(elimination multiplying equation 2 by -0.5)
.25(x) + 0.05(y) = 4.90
-0.05(x) - 0.05(y) = 42 * (-0.05)
(3) Resulting equation
.20(x) = 2.8
x = 14
plug x into equation 2
14 + y = 42
y = 28
There are 14 quarters and 28 nickels in Mary's collection.
Answer:
36.8/2.8 = 16
Expression 1 = 368/28
Expression 2 = 3.68/.28
Step-by-step explanation:
If you move the decimal the same on both numbers of a division problem the answer stays the same.
If this is a graph, I attached the file.
The minimum is (122.222, 3277.778)
The y intercept is (0,10000)
The graph: .45x^2-110x+10000
