Part A:
175x+2250=150x+2750
(Subtract 150x from both sides)
25x+2250=2750
(Subtract 2250 from both sides)
25x=500
(Divide by 25
x=20 months Part B: 175(20)+2250
3500+2250=5750
She would have to pay $5,750
What kind of things are we learning that this experiment needs to be about??
Answer:
The solution is (-1/2, 3 1/2), or (-0.5, 3.5)
Step-by-step explanation:
Seeing that -x + 3 = y (in the second equation), substitute -x + 3 for y in the first equation, obtaining:
-x + 3 = 3x + 5
Combining the x terms, we get
3 = 4x + 5
Combining the constants, we get
4x = -2, or x = -1/2
Seeing that -x + 3 = y, substitute -1/2 for x and calculate y:
-(-1/2) + 3 = y = 3 1/2
The solution is (-1/2, 3 1/2), or (-0.5, 3.5)
