Answer: 12
40% = 40/100 = 0.40
"of" means "multiply" in percent word problems like this. Multiply 0.40 with 30 to get 0.40*30 = 12
Optionally, you can solve the equation below for x
part/whole = percent/100
x/30 = 40/100
x/30 = 0.40
x = 0.40*30
x = 12
much of those steps follow a similar pattern to what was mentioned earlier.
Answer:
Number of games won by Steelers = 40
Number of games lost by steelers = 8
Step-by-step explanation:
Ratio of wins to losses the Steelers have over the Bengals = 5:1
Total number of games the have played each other in past 15 years = 48
Let number of games won by Steelers be = ![5x](https://tex.z-dn.net/?f=5x)
Let number of games lost by Steelers be = ![x](https://tex.z-dn.net/?f=x)
Total number of games played = ![5x+x=6x](https://tex.z-dn.net/?f=5x%2Bx%3D6x)
So, we have
[Total number of games played]
Dividing both sides by 6.
∴
Number of games won by Steelers = ![5\times 8 = 40](https://tex.z-dn.net/?f=5%5Ctimes%208%20%3D%2040)
Number of games lost by steelers = 8
You take the IN(x) numbers and plug them one at a time for x in the equation. For example the first IN(x) is -6. Your equation is y=-2x. So you plug negative 6 in place of x in the equation. So the new equation is y=-2(-6). Hope this helps.
