Joe's Painting: 20x + 100 = y
Steve's Painting: 15x + 120 = y
x = hours worked
y = total income
We can find when the two equations intersect by making them equal to each other. That means we put an equal sign in the middle. So, it would look something like this:
20x + 100 = 15x + 120
First, we have to move the 100 by subtracting it from both sides.
20x = 15x + 120 - (100)
20x = 15x + 20
Then, we need to move the 15x by subtracting it from both sides.
20 - (15x) = 20
5x = 20
Lastly, we need to divide 5 from both sides.
5x = 20/5
x = 4
Therefore, Joe and Steve would have to work for 4 hours in order for their models to be equal to each other.
What does that 3/x and 2/x mean? 2x and 3x or x^2 and x^3?

The correct statement is that the probability is B. Event F for female and event D for drama are independent events.
<h3>What are independent events?</h3>
It should be noted that two events are independent when the occurence of one doesn't affect the probability of another one occuring.
The probability of females will be:
= 3/5 = 0.6
The probability of drama will be:
= 40/240 = 0.167
In this case, they're both independent.

Answer:
26/36 numbers are greater than 10
Simplify
13/18
Multiply by the chance of getting tails
13/18 x 1/2 = 13/36
13/36 your answer
26 wanted numbers / 36 amount of numbers
1 tails / 2 sides
