Answer:
d. 13.5, 20.25
Step-by-step explanation:
An exponential function is monotonic and does not change sign. On this basis alone, the first three choices can be eliminated.
The common ratio is 6/4 = 3/2.
The term in the sequence after 9 is 9·(3/2) = 27/2 = 13.5.
The term in the sequence after 27/2 is (27/2)·(3/2) = 81/4 = 20.25.
Answer:
n=9
Step-by-step explanation:
7n+5=68 Subtract 5 on both sides.
<u>-5 -5</u>
7n=63 Divide both sides by 7.
<u>/7 /7</u>
n=9
Hope this helps! Have a nice day ^^
Answer:
5 7/6 or 6 1/6 either one works they are the same number just one is not simplified
All the corners of a rectangle is equal to 90 degrees. So you need to set (x-1) and (2x+10) equal to 90 and then solve for x.
(x - 1) + (2x + 10) = 90
<em>Combine the like terms...
</em>3x + 9 = 90
<em>Subtract both sides by 9...
</em>3x + 9 - 9 = 90 - 9
3x = 81
<em>Divide both sides by 3...
</em><em>3x = 81
</em>(3x) / 3 = 81 / 3
x = 27
