An air traffic controller is tracking two planes. To start, Plane A was at an altitude of 432 meters, and Plane B was just taking off. Plane A is gaining altitude at 16 meters per second, and Plane B is gaining altitude at 25 meters per second. For each plane write an expression for the altitude of the plane after x seconds and Write and equation to show that the two planes are at the same altitude.
Plane A = 432 + 25x Plane B = 16x Equation 432 + 25x = 16x
Plane A= 432x + 16 Plane b=25x Equation 432x + 16 = 25x
Plane A= 432 +16x Plane b= 25x Equation 432 + 16x = 25x
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $20 monthly fee and charges an additional $.08 for each minute of calls. The second plan has no monthly fee but charges $.12 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?
500 minutes
550 minutes
20 minutes
6000 minutes
Solve for a in the equation 18 + a = b
a = -b -18
a= 18 - b
a = b -18
Solve for x in the equation z= (x -5)k
x= (z +k) -5
x = z/k + 5
x = z + k + 5
Solve for c in equation a = 1/3(b + c - d)
c = (a - b + d) / 3
c = 3a - b + d
c = 3a -3b + 3d
Solve for w. 2w + 5 = 4w + 13
w=8
w=4
w=-4
w=-8
Solve for u. -4(-6u+4) - 3u = 6(u-1)-5
u= 1/3
u = -1/3
u = 2/3
u = -2/3
Solve for x. -9/x = -15/x + 2
z=-2
z=2
z=-3
z=3
