There are 4 quarts in a gallon to find how many times he will use the container to fill the aquarium you need to multiply 4 by 5:
4×5=20
Milton with fill the container 20 times before the container is full
hope this helped
Answer:
Range: 1 > x > 3
Step-by-step explanation:
We are given then function;
y = x³ - 6x² + 9x + 5
dy/dx = 3x² - 12x + 9
We want to find the range of values of x for which dy/dx > 0
Thus;
3x² - 12x + 9 > 0
Using quadratic formula, we have;
x = 1 and x = 3
Let's define the range;
try x = 0
3(0²) - 12(0) + 9 = 9
This is more than 0, so it is part of the solution.
Let's try x = 4
3(4²) - 12(4) + 9 = 9
This is more than 0 so it is part of the solution
Let's try x = 2
3(2²) - 12(2) + 9 = -3
This is less than 9 and so it's not part of the solution.
Thus the range of values of x for which dy/dx > 0 is;
1 > x > 3
Answer:
Let x = the number of quarters
Let y = the number of nickels
X + y = 62 x = 62 - y
.25x + .05y = 12.50 Multiply both sides of the equation by 100 to get rid of the decimal points.
25x + 5y = 1250
25(62-y) + 5y = 1250
1550 - 25y + 5y = 1250
-20y = -300
y = 15 nickels
x = 62 - y = 62 - 15
x = 47 quarters
The answer is 3x - 5y = 26 i believe !
Well because they gave us a few numbers in the question, it is certain that the other side could be the same number as the left side so x=(2)+3 y=(1)+1
