i'm doing this as a system, ok?
x + y = 12
- x = - y - 10
x + y = 12
-x + y = -10
2y = 2
y = 1
x + 1 = 12
x = 11
so, the ordered pair is (11, 1) -> remember that the x always comes first

Answer:
9(5e-3f)
Step-by-step explanation:
so, to start, you want to see what they have in common. the variables are not the same, so you cannot take a variable out; however, 45 and 27 have something in common. they can both be divided by 9! (this is a skill you will have to practice). so, after recognizing this, you can divide both numbers by 9, and you would have 5e-3f. however, we cannot just change that because that is not equal to 45e-27f. so, we make sure we include what we did. because we divided by nine, we are going to put the greatest common factor outside of the numbers after we put them in parentheses. 9(5e-3f). we do this because multiplication is the opposite of division, and so this just shows that if we use the distributive property, it would multiply back out to 45e-27f. I hope this helps!
Answer: 55 performances are needed to break even.
Step-by-step explanation:
Let x represent the number of musical performances that are made.
Producing a musical costs $88,000 plus $5900 per performance. This means that the total cost of x musical performances would be
88000 + 5900x
One sold-out performance earns $7500 in revenue. If every performance sells out, it means that the total revenue would be
7500 × x = 7500x
In order to break even, total cost would be equal to total revenue. Therefore,
7500x = 88000 + 5900x
7500x - 5900x = 88000
1600x = 88000
x = 88000/1600 = 55
The answer is HL since the hypotenuse and legs of both triangles are the same length
