Answer:
x>3
Step-by-step explanation:
8x-6>12+2x
Subtract 2x from both sides:
6x-6>12
Add 6 to both sides:
6x>18
Divide both sides by 6:
x>3

Your answer should be 81 for a. I got this result by multiplying 9 by 9.
We can easily convert grams to pounds and find that 1 g of coffee beans is 0.00220462 pounds. Now we can multiply that value with 60 cups to find how many cups it makes.
We find that it makes 0.1322772 cups.
Then we know that 236.588 milliliters are in a cup. We multiply the value of the coffee available with 1 g of coffee beans (in cups - of course) and get the value the question asked :
0.1322772 * 236.588 milliliters
The answer is 31.2951981936 milliliters!
Hope this helps!
Answer:
cos θ = 1/2
Step-by-step explanation:
4 cos θ + 4 sin² θ = 5
Use Pythagorean identity.
4 cos θ + 4 (1 − cos² θ) = 5
4 cos θ + 4 − 4 cos² θ = 5
0 = 4 cos² θ − 4 cos θ + 1
0 = (2 cos θ − 1)²
0 = 2 cos θ − 1
cos θ = 1/2
