The common difference is basically the second number minus the first (or the 3rd-2nd, and so on). The answer should be B.
The particle will reach 50 km/hr when x = 32.25 hours
Step-by-step explanation:
A physicist working in a large laboratory has found that light particles
traveling in a particle accelerator increase velocity in a manner that
can be described by the linear function - 4 x + 3 y = 21, where
- x is the time in hours
- y is the velocity in kilometer per hour
We need to find when a certain particle will reach 50 km/h
∵ - 4 x + 3 y = 21 is a linear function
∵ x represents the time (number of hours)
∵ y represents the velocity in km/h
∵ The velocity of a particle will reach 50 km/h
- Substitute y by 50 in the function above
∴ - 4 x + 3(50) = 21
∴ - 4 x + 150 = 21
- Subtract 150 from both sides
∴ - 4 x = -129
- Divide both sides by -4
∴ x = 32.25 hours
The particle will reach 50 km/hr when x = 32.25 hours

Answer:
20
Step-by-step explanation:
TO find the answer, use multiplication.
When one part of a fraction multiplies, you multiply the other number with it. 22x3 is 66, so divide 60 by 3. You get 20. n=20. Hope it helps.
You can use ratio. 60:66 is n:22. 22 goes into 66 3 times, and 20 goes into 60 3 times too, so 20:22 is equivalent to 60:66

Answer:
y= 3/13x + 2/13
Step-by-step explanation:
3x-13y=2
Subtract 3x from both side
-13y=-3x-2
Divide by -13
y= 3/13x + 2/13
4x - 3y = 34
3x + 2y = 17
first equation should be multiplied by 2...second equation should be multiplied by 3
