Based on the ratio of boys/girls We can infer that the only possibility for Ellen's math class would be answer B. 14/21
The line that has the slope of 2 is Line C.
<span>-3x + 2y = 2 eq (1)
7x - 3y = 7 eq (2)
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1)
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)
Answer: option B. (4,7)

30 + 2w = 2 • (w - 15)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation
Solve : w-15 = 0
Add 15 to both sides of the equation :
w = 15
Answer:
Company needs to sell at least 34 tickets in order to make a profit.
Step-by-step explanation:
Given:
Rent for the space = $300
Cost per tickets = $9
Let the number of tickets sold be 'x'
We need to find the least number of tickets to be sold to make profit
Now total profit can be made if amount which is made after selling number of tickets is greater than 300.
Hence the equation can be framed as,

Solving the equation to find the value of x we get;
We will use Division property and divide both side by 9 we get;

Tickets which need to be sell cannot be in point value hence rounding to whole number we get;

Hence Company needs to sell at least 34 tickets in order to make a profit.
