To find out how long Marsha and Sílvio practiced, we set up the equation x + 2x = 90, where x is the time Sílvio practiced. Solving the equation, we found that Sílvio practiced for 30 minutes and Marsha for 60 minutes.
The question asks us to solve for the amount of time Marsha and Sílvio each practiced their instruments given that Marsha practiced for twice the time that Sílvio did and together they practiced for a total of 90 minutes.
Let's denote the time Sílvio practiced as x minutes. This means Marsha practiced for 2x minutes. We know that the sum of their practice times is 90 minutes, which gives us the equation:
x + 2x = 90
Combining like terms, we have:
3x = 90
Dividing both sides by 3 to solve for x gives:
x = 30
Therefore, Sílvio practiced for 30 minutes and Marsha practiced for 60 minutes (double the time of Sílvio).

Net income
Using this formula
Net Income = Gross Profit - Operating Expenses
Where:
Net Sales = Revenue - Returns
Net sales=$6,825 -$215
Net sales=$6610
Cost of goods sold= Beginning Inventory + Purchase - Ending Inventory
Cost of goods sold =$780 + $1,795 - $795
Cost of goods sold=$1780
Gross Profit = Net Sales - Cost of goods sold
Gross profit =$6610 - $1780
Gross profit=$4830
Operating Expenses:
Wages $1,460
Rent $650
Utilities $185
Advert $90
Tax $125
Total Operating Expenses $2,510
Let plug in the formula
Net income=$4,830 - $2510

What two ratios are equivalent to 11/12
the sum of two numbers is 70 and their difference is 24.Find the two numbers
The two numbers whose sum is 70 and has a difference of 24 is 23 and 47
Let
x = smaller number
y = Larger number
y + x = 70 (1)
y - x = 24 (2)
subtract (2) from (1) be to eliminate y
x - (-x) = 70 - 24
x + x = 46
2x = 46
x = 46 / 2
x = 23
substitute x = 23 into (1)
y + x = 70
y + 23 = 70
y = 70 - 23
y = 47
Therefore, two numbers whose sum is 70 and has a difference of 24 is 23 and 47

The answer would be the top right graph where none of the lines intersect since it shows that there is no possible real solutions for the system if none of the lines intersect on a certain point.
Remember: If the lines intersect, there is a solution; if the lines do not intersect, there is no solution; if the lines fall on the same line, or the equations are equivalent, then the solution is all real numbers.
