2x + 5 > 9
so 2x > 9-5
2x > 4
x > 2
5x <= 30
x <= 6
answer is 2 < x <= 6
or interval notation it is (2, 6]
Answer:

Your answer box probably doesn't want the curly brackets and maybe not the spaces, either. Those brackets are used to identify a <em>set</em> of values.
Answer:
1a w=-9 1b s=20/7
2a x=12 2b v=11
3a b=10 3b a=9/5
4a c=1 4b x=2

Answer:
90°
Step-by-step explanation:
Angle C = arccos((84²+13²-85²)/(2×84×13))
= arccos(0/2184)
= arccos(0)
= 90°

Answer: D
Step-by-step explanation:
1. Subtract 36 to 28.80
2. Divide the answer to the first price (36.00)- 7.5 divided by 36.00 or 36
3. When you calculate and find the answer as a decimal, then make it into a percentage
So if... you divide 7.5 divided by 36, you get the decimal of 0.2, and when you move the decimals two places only, you get your answer of 20%.
Hopefully it helped you!. Have a good day :-).
