Answer:
91%
Step-by-step explanation:
Let's set up an equation:
182=x%200
Change x% into x/100 to make the math easier
182=x/100(200)
182=2x
Divide both sides by 2
x=91
They won 91% of the games
Answer:
1000
Step-by-step explanation:
Lets just say x is the bigger number. We can create two equations.
x + y = 70
x - y = 30
If we add these equations together, we get that:
2x = 100
and that
x=50
Plugging x back into any of the equations gets us that y = 20, so xy = 20*50 = 1000
Answer:
x=1/15 y = -4 1/3
Step-by-step explanation:
First combine like terms.
-3y = 13
y= -13/3
y= -4 1/3
Substitute for y in next equation
-4 1/3 = 5x - 4
5x = 4 1/3 - 4
5x = 4 1/3 - 4
5x = 1/3
x = 1/3 divided by 5
Since fractions can't be divided, multiply by the inverse
x = 1/3 times 1/5 = 1/15
Answer:
P(yellow the red) = 
Step-by-step explanation:
P(yellow and red) = P(yellow then red) + P(red then yellow)
P(yellow then red) = 
P(red then yellow) = P(yellow then red)
P(yellow and red) =
