Let's work out the process to find the numerator:
(x+2)/2 - (x+1)/3x Factor using the LCD, 6x
3x(x+2)/6x - 2(x+1)/6x
(3x² + 6x - 2x - 2)/6x
= (3x² + 4x - 2)/6x
Answer is 3x² + 4x - 2
Hopefully I did this correct, Not to good with math c':
Answer:
v = Δs/Δt
Step-by-step explanation:
This: Δs is the change in speed or can also be the rate
This: Δt is the change in time
it would be .05, if it was off by that much the decimal number would increase
so if the board measured 34.15 it would round to 34.2
Answer:
0.5x+20=0.25x+30, m=40
Step-by-step explanation:
Blue: y=0.5x+20
Red: y=0.25+30
We’re looking for where the y (cost) is equal, so we can set the two equations to each other:
Isolate x:
0.5x+20=0.25x+30
0.5x+20-20=0.25x+30-20
0.5x=0.25x+10
0.5x-0.25x=0.25x+10-0.25x
0.25x=10
x=40
m= 40
