Answer:
32
Step-by-step explanation:
Add up all the numbers and then divide by how many numbers there are.
Tan(x)= sin(x)/cos(x), therefore, substitute sin(x)/cos(x) in the expression:
=(cos(x)(sin(x)/cos(x))-1)/cos^2(x)
simplify the 2 cos(x):
=(sin(x)-1)/cos^2(x)
Sin^2(x)+ cos^2(x)=1, sin^2(x)-1=- cos^2(x), substitute in the expression:
= -cos^2(x)/cos^2(x)= -1
The answer is B) 20 lbs for $22 because carol is getting 8 pounds more for only $9+

Answer:
x < -3
Step-by-step explanation:
2x - 3 < -9
Add 3 to each side
2x - 3+3 < -9+3
2x < -6
Divide by 2
2x/2 < -6/2
x < -3
