Solve: 75x - 1 = 343
---> 75x - 1 = 73
---> 5x - 1 = 3
---> 5x = 4
---> x = 4/5
First, do 7^5, which is equal to 16807.
Then you have 16807x-1=343
Add the one to the 343 in order to isolate your variable.
16807x=344
Divide both sides by 16807, and you're left with
x=0.02046766228
or
x≈0.02
It depends. If the selection is made WITHOUT REPLACEMENT, then the probability of the first can is 12% = 12 out of 100 = 6 out of 50 = 3/25. The probability of the 2nd can is then 5 out of 49 (assuming the first can is bad). We multiply the two separate probabilities to get the probability of the two events together: (3/25) * (5/49) = (3/245) = Answer "A".
But nothing says that the control worker couldn't make the selection WITH REPLACEMENT. If so, then the probability of the first can is 12/100, and the probabilty of the 2nd can is also 12/100. The two events together is (12/100) * (12/100) = (9/625) = Answer "C".
-2 ÷ (-3 + 2)=2
no idea
Yep, if it were a number, it would still be infinity, as kraykracker said.
2x+4=22-7x
9x=18
x=2
3*2=6
3*7=21
3
It would, I believe, be infinity.
Or it could just be what Landry said. Lol :P
Infinity is not a number, and so can not be divided by two.
2 1/4
0.28888888888 Lmao
I assumed that is what the original poster meant. Maybe not.
Momentum=Mass x Velocity(Speed). Multiply the mass of each ball by its speed and whichever product is greater, then the product of that ball has greater momentum.
Hi, Welcome to Web2.0Calc!
Clearly there is a solution!
geno gave both an exact and an approximate result. The fact that the approximate solution doesn't match the original equation exactly is hardly surprising!
That is quadratic formula not quadratic eqaution.
ax2 + bx + c
\(x = {-b \pm \sqrt{b^2-4ac} \over 2a}\)
\(5\times9\times19\times402,838\)
\(45\times19\times402,838\)
\(855\times402,838\)
\(344,426,490\)
The 6th term should be= -3,072
