Answer:
$7.25
Step-by-step explanation:
I'm pretty sure I'm correct. Hope this helps and have a nice day!
Answer:
The short answer is there isn’t.
Start by writing each of these as an expression:
x * y = 60
x + y = 7
Next, solve each for the same variable; in this case, y:
(x * y) / x = 60 / x
.: y = 60 / x
(x + y) - x = 7 - x
.: y = 7 - x
Next, replace y of the second expression to the first
y = 60 / x & y = 7 - x
.: 7 - x = 60 / x
Now, solve for x:
(7 - x) * x = (60 / x) * x
.: x * 7 - x^2 = 60
This is quadratic, so write it in the form of ax2 + bx + x = 0
(-1)x^2 + (7)x + (-60) = 0
.: a = -1, b = 7, c = -60
Finally solve for b:
x = (-b +- sqrt(b^2 - 4*a*c)) / 2a
.: x = (-7 +- sqrt(7^2 - 4*-1*-60)) / (2 * -1)
.: x = (-7 +- sqrt(49 - 240)) / -2
.: x = (-7 +- sqrt(-191)) / -2
The square root of a negative value is imaginary and thus there’s no real answer to this problem.
Answer:
1.76 liters per minute.
Step-by-step explanation:
The answer is 1.76 because 105.6 divided by 60 is 1.76
P.S Can I have brainliest?
The product of 6 and 4 is 24. The difference of 7 and 3 is 4.
Therefore, 24+4 = 28.
Answer:
f(x)=0 or 8 I'm honestly not sure which but I know one of these is right
Step-by-step explanation:
subtract x^2-2x from both sides -x^2+8x=0
factor left side of the equation x(-x+8)=0
set factors equal to zero
x=0 or x=-x+8=0
x=0 or x=8
HOPE THIS HELPS!!! :)
