Green = g
Blue = b
Red = r
g+b = 1500
g+r = 750
g+b+r = 2000
in the 1st equation solve for b
g+b =1500
b = 1500-g
2nd equation solve for r
g+ r = 750
r = 750-g
now substitute the answers fro. b and r into the final equation.
g+b+r = 2000
g + 1500-g + 750-g = 2000
-g + 2250 = 2000
-g = -250
g = 250
So we k own the green bike is $250.
Blue = 1500- g
blue = 1500-250= $1250
red = 750-g
red = 750-250 = $500
Answer:
ill explain better
Step-by-step explanation:
use distrubrity property and you get 6x + 6x -18y+6+(-9) then you add 18 because you have to get the y way so you do the opposite of subtracting which is adding so when you add the 18 to it self you then add the 18 to one of the 6x the you get 24x+6x+-4 which u add 6 to -9 the to combine like terms and get 30x+-4
Answer:
An object moving along the x-axis is said to exhibit simple harmonic motion if its position as a function of time varies as
x(t) = x0 + A cos(ωt + φ).
The object oscillates about the equilibrium position x0. If we choose the origin of our coordinate system such that x0 = 0, then the displacement x from the equilibrium position as a function of time is given by
x(t) = A cos(ωt + φ).
A is the amplitude of the oscillation, i.e. the maximum displacement of the object from equilibrium, either in the positive or negative x-direction. Simple harmonic motion is repetitive. The period T is the time it takes the object to complete one oscillation and return to the starting position. The angular frequency ω is given by ω = 2π/T. The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = ω/2π of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
The velocity of the object as a function of time is given by
v(t) = dx(t)/dt = -ω A sin(ωt + φ),
and the acceleration is given by
a(t) = dv(t)/dt = -ω2A cos(ωt + φ) = -ω2x.
Answer:
A
Step-by-step explanation:multiply both sides by two, then subtract b and c from both sides to get a on the right side by itself
Answer:
Step-by-step explanation:
Well if you want the answers there are 3 different ways
x = 12/5
or
x = 2.4
