She can make 260 batches. You are converting liters to millimeters.
1 liter= 1000 milileters
0.26 x 1000 = move 0.26 over to the left of the decimal point the number of zeros in 1000 (i.e.3)
Answer:
(1/2, 9/2)
Step-by-step explanation:
Write the system as a column (not as a row of characters):
x − 3y = –13 and 5x + 7y = 34 =>
x − 3y = –13
5x + 7y = 34
Let's eliminate x using the method of addition and subtraction. Multiply all terms of the first row by -5:
-5x + 15y = 65
5x + 7y = 34
The sum of these two equations is
22y = 99, and so
y = 9/2
Substituting 9/2 or y in the first equation, we get:
x - 3(9/2) = -13, which simplifies to:
x = 27/2 - 13, or
x = 27/2 - 26/2, or x = 1/2
Then the solution is (1/2, 9/2)
From the calculation done below, the interest when the rate is 9% is $101.25.
<h3>How interest is calculated using direct variation?</h3>
Since the interest on investment varies directly as the rate of interest, the relevant direct variation formula to use to calculate investment is as follows:
i = kr ................................. (1)
Where:
i = interest amount = $45
k = investment = ?
r = interest rate = 0.04
Substituting the values into equation (1) and solving for k, we have:
45 = k0.04
k = 45 / 0.04
k = $1,125
To find the interest when the rate is 9%, we substitute k = $1,125 and r = 9% into equation (1) as follows:
i = $1,125 * 9% = $101.25

Answer:
65 points in all
Step-by-step explanation:
3 x 3 = 9
7 x 8 = 56
56 + 9 = 65
:))
B does not lie on the graph of the line -2x + 3y = 6
If we substitute the x and y value from B into the equation; ( 6 = x and -2 = y), both sides of the equation will not be equal;
-2x + 3y = 6
-2 (6) + 3(-2) = 6
-12 + (-6) = 6
-18 = 6
Since both sides of the equal sign are not 6, the point does not lie on the line.
