<u><em>Answer: </em></u>
#9: 5
#10: -2
#11: -1.5
<em><u>Step-by-step explanation:</u></em>
<em><u>#9:</u></em> 3,8,13,18,23,(28),(33),(38),.. <em>Go up by 5 each time, so the common difference is </em><u><em>5</em></u><em>.</em>
<u><em>#10:</em></u> 11,9,7,5,3,(1),(-1),(-3),... <em>Go down </em><em>(-)</em><em> by 2 each time, so the common difference is </em><u><em>-2</em></u><em>.</em>
<u><em>#11:</em></u> 3, 1.5, 0, -1.5, -3, (-4.5), (-6), (-7.5),... <em>Go down </em><em>(-) </em><em>by 1.5 each time, so the common difference is </em><u><em>-1.5</em></u><em>.</em>
Answer: 
Step-by-step explanation:
Given the right triangle in the image, you need to remember the following identity:
Observe the triangle. You can identify that:
Then, knowing these values, you can substitute them into :
Finally, you have to solve for "x".
Therefore, the value of "x" rounded to the nearest tenth is:
Fraction 125g of 1kg:
1 kg = 1000 gr
so,
125/1000 = 1/8

Answer:
<h2>510</h2><h2 />
Step-by-step explanation:
30-22=8
22-14=8
14-6=8
then
→ the common difference r = 8
→ the first term = 6
THerefore, (accoriding to the standard explicit formula)
the 64th term = term 1 + (64 - 1)×r
= 6 + 63×8
= 510
