Hence, the sum of a 7-term geometric series is:
-32766.
<h3><u>
Step-by-step explanation:</u></h3>
We have to find the sum of a 7-term geometric series (i.e. n=7) if the first term(a) is -6, the last term is -24,576, and the common ratio(r) is 4.
We know that the sum of the 7-term geometric series is given as:
On putting the value of a,n and r in the given formula we have:
Hence, the sum of a 7-term geometric series is:
-32766.

The answer would be 15 +20x. You have to combine like terms.
2+6+7+20x
8+7+20x
= 15+ 20x (answer)
Answer:
Clare's score was 70.
Step-by-step explanation:
N = 20
M = 30
C = ?
Mean = (Sum of all values)/3
40 = (20 + 30 + c)/3
40 = (50 + c)/3
50 + c = 120
c = 70
<h3>−2x + 14 = 12</h3>
<em>Subtract</em><em> 14 </em><em>from both sides.</em>
<h3>−2x = 12 − 14</h3>
<em>Subtract </em><em>14</em><em> from </em><em>12 </em><em>to get </em><em>−2.</em>
<h3>−2x = −2</h3>
<em>Divide both sides by</em><em> −2.</em>
<h3>x= -2/-2</h3>
<em>Divide </em><em>−2</em><em> by </em><em>−2</em><em> to get 1.</em>
<h3>x = 1</h3>
