Answer:
B (2 violet)
Step-by-step explanation:
Let the colors be represented by their first letter. Then the balances give rise to two equation:
o +y +b +v = r +g +b
o +y +v = g +v
Subtracting the second equation from the first gives ...
(o +y +b +v) -(o +y +v) = (r +g +b) -(g +v)
b = r +b -v
Adding v-b to both sides, we have ...
b +(v -b) = r +b -v +(v -b)
v = r
Multiplying this result by 2, we can match the final balance:
2r = 2v . . . . . . . choice B
The way to multiply fractions include:
- The first step when multiplying fractions is simply to multiply the two numerators.
- The second step is to multiply the two denominators.
- Finally, simplify the new fractions
<h3>What are fractions?</h3>
It is important to note that fractions are part of whole numbers.
Fir example, to multiply 2/3 by 1/5 will be:
= 2/3 × 1/5
= 2/15
In conclusion, one has to multiply the numerator and them multiply the denominator.

Answer:
Step-by-step explanation:
problem 4
Velocity is +2.0m/s and constant acceleration is -0.5m/s^2
For every second the velocity drop by 0.5 m/s, so after 2 seconds the velocity is 1 m/s.
problem 5
Accelerate from rest to 28m/s means go from 0 to 28m/s so with
a constant acceleration of 5.5 m/s^2 it will take 5.09 second
