For this case we have the following system of equations:
We can write a system of equivalent equations.
For this, it is enough to multiply one of the two equations by a scalar.
Multiplying the equation 1 by 2, we have:
Therefore, the new system of equations is:
Answer:
A system that is equivalent is:

Answer:
D, 0.19
Step-by-step explanation:
So first you add up all the candies
you’ll get 79 pieces of candy
So 4 pieces of green candy
So we can just subtract 4 from 79 you’ll get 75 pieces
It still works becuase we know that 4 pieces gone are green so the other candies still have the same amount
Now there are 14 red pieces
So 14/75
Now simplify that and you’ll Get
0.18666666
Now round that, 0.19
Answer:
10.5
Step-by-step explanation:
sin29
k
=
sin124
18
Plug in. Opposite sides go together.
k=\frac{18\sin 29}{\sin 124} \approx 10.526 \approx 10.5
k=
sin124
18sin29
≈10.526≈10.5
Multiply both sides by the reciprocal (-8/7). You would get 40/7 or 5.71428571
