Ratio is 10:16, so to win 50, its 50:190, so you need to play 190 games to win 50
7(72) + 0.10(2574) = 504 + 257.40 = 761.40 <== this is how much she will earn. Your gonna have to pick the answer choice that is the closest since no answer choices were given.
Finding x:
If y=2x+9, substitute y into the equation x-3y=-12.
You will get: x-3(2x+9)=-12
Now, distribute: x-6x-27=-12
Add like terms: -5x-27=-12
Add 27 to both sides: -5x=15
Divide both sides by -5: x=-3
Now, substitute this value of x into the equation to find y: y=2(-3)+9
Multiply: y=-6+9
Add: y=3
Here is the solution: (x,y)=(-3,3)
Hope this explanation helped!
Answer:
x = 30.97 ( to nearest hundredth).
Step-by-step explanation:
5^x = 8^x-7
Taking logs of both sides:-
ln 5^x = ln 8^x
By the law of logarithms:-
x ln 5 = (x - 7) ln 8
x / (x - 7) = ln 8 / ln 5
x / (x - 7) = 1.292
x = 1.292x - 9.044
1.292x - x = 9.044
x = 9.044 / 0.292
= 30.97 (answer)
