Answer:
Z=8 is the answer
Step-by-step explanation:
first, you add 8 to both sides which leaves you with 5z=40. then after that you divide both sides by 5 which leaves you with 5/5z = 40/5. then buy dividing 5 by 5 its leaves you with 1 which is equal to z because blank variables equal 1. On the other side if the equation 40 by 5 is 8 so that leaves you with z=8
I believe the answer is D. because -12 + -1 equal -13
540 degrees is equivalent to 180 degrees. Cotangent and cosecant are invalid, sine, secant, tangent are all 0 and cosine is -1.
The third option should be correct
Percent means parts out of 100 so
28%=28/100 or 0.28
'of' can be translated as multiply
28/100 times 14,350=401800/100=4018 or
0.28 times 14,350=4018
