You would add 3 on both sides
3x - 3 + 3 = 13 + 3
3x = 16
Answer:It's 63.25
Step-by-step explanation:
because 3.072 it's a physically number
For this case we must solve the following system of equations:
We multiply the first equation by -2:
We add the new equation with the second one:
We have different signs subtracted and the sign of the major is placed:
Now we find the value of the variable "y":
Thus, the solution of the system is given by:
Answer:
use the number it and equation it with number and new number will form
In 22, you're looking for the vertical height of the triangle. You're given the angle opposite the side you want to find (which I'll call
) and the length of the hypotenuse. This sets you up with the relation
In 23, you're given a similar situation, except now you're looking for the angle (I'll call it
) in the triangle opposite the side denoting the height of the airplane. So this time,
