Answer:
<u>6.975 pints of blue paint</u>
Step-by-step explanation:
1/4x + 3/4y = 9.3
9.3/4 = 2.325
2.325 = 1/4
2.325 * 3 = 6.975
let me know if I am incorrect
Step-by-step explanation:
This is what I know there are 54 students who learn salsa and 23 ballet left with 31 students (put that aside) then 15 who learned salsa instead of ballet. (31 - 15 = 16. Left with 16) but 10 who did not learn either ballet or salsa (16-10 = 6.)
Do u understand where I'm going.......Im starting to get confuse myself now

If you would like to solve 1/(x + 3) = (x + 10)/(x - 2), you can do this using the following steps:
<span>1/(x + 3) = (x + 10)/(x - 2)
</span>1 * (x - 2) = (x + 10) * (x + 3)
x - 2 = x^2 + 3x + 10x + 30
0 = x^2 + 13x + 30 - x + 2
0 = x^2 + 12x + 32
0 = (x + 8) * (x + 4)
1. x = -8
2. x = -4
The correct result would be x = -8 and x = -4.
Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
