Answer:
36
Step-by-step explanation:
Using the angle addition postulate
angle 1+angle 2+angle 3=180
Angle 2 is 90 degrees,
Angle 1 is 2x degrees
Angle 3 is 3x degrees
Plug this into equation




Plug 18 into 2x

Answer:
is that a test or homework
Step-by-step explanation:
I'm a kid so I have no idea
3.75 You would multiply 7.5(for 7 1/2) X 0.50=3.75. Hope this helps.
I'll go out on a limb and guess the system is

with initial condition

. The coefficient matrix has eigenvalues

such that

The corresponding eigenvectors

are such that




So the characteristic solution to the ODE system is

When

, we have

from which it follows that

and

, making the particular solution to the IVP

Answer:
The first one (Cedric is correct because he used the inverse of subtraction and added 4.5)
Step-by-step explanation:
First....I'll do it my way
z - 4.5 = -1.5
Add 4.5 on both sides
z - 4.5 + 4.5 = -1.5 + 4.5
z = 3
This should be our answer.....and so who did it right?
Cedric did
Which is the true statement?
Cedric is correct because he used the inverse of subtraction and added 4.5
Hope this helped!
Have a supercalifragilisticexpialidocious day!
