b. -2.5 × 10-4 is the answer
The answer is C Because 60x is implying 60 by a variable and the + 2000 Implies it’s already at 2000
Solution for (-4z^2-11u)-5z^2=
<span>Simplifying
(-4z2 + -11u) + -5z2 = 0
Reorder the terms:
(-11u + -4z2) + -5z2 = 0
Remove parenthesis around (-11u + -4z2)
-11u + -4z2 + -5z2 = 0
Combine like terms: -4z2 + -5z2 = -9z2
-11u + -9z2 = 0
Solving
-11u + -9z2 = 0
Solving for variable 'u'.
Add '9z2' to each side of the equation.
-11u + -9z2 + 9z2 = 0 + 9z2
Combine like terms: -9z2 + 9z2 = 0
-11u + 0 = 0 + 9z2
-11u = 0 + 9z2
Remove the zero:
-11u = 9z2
Divide each side by '-11'.
u = -0.8181818182z2
Simplifying
u = -0.8181818182z<span>2</span></span>
Given :
Hans is using frequent flier miles to fly to a location 450 miles away, but the airline he is using still charges $15.89 for fees and taxes and $0.17 to redeem each mile.
In the equation below, x represents the distance Hans is flying, and y represents the cost of the trip. y = $0.17x + $15.89 .....1)
To Find :
How much did Hans pay for his trip.
Solution :
x = 450 miles.
Putting value of x in equation 1 we get :
y = $(0.17×450 + 15.89)
y = $(76.5+15.89)
y = $92.39
Therefore, Hans will pay $92.39 for his trip.
Hence, this is the required solution.
