Answer:
x = -4/5 = -0.800
Step-by-step explanation:
Pull out like factors :
-12 - 15x = -3 • (5x + 4)
Solve :
-3 = 0
Solve :
5x+4 = 0

Answer:
mean = 52
Step-by-step explanation:
Just add all four together and divide by 4. That's the mean.
Sum (49 + 43 + 53 + 63) = 208
Mean = 208 /4 = 52
We can solve for the value of x by applying the principles of sine and cosines method and laws of the inversed sign.
Given:
sin64°=cosx
Perform sin64° which is equal to 0.8987940463
0.8987940473=cosx
perform inverse sign:
cos-0.8987940473=x
x=26°
Therefore, the value of x is 26°.
