Answer:
x = -1
Step-by-step explanation:
8-2x=-8x+14
8-14=-8x+2x
-6/-6=x
x=-1
Making 10 chairs would take Marjorie and Blaine<u> </u><u>21 hours and 40 minutes</u>.
<h3>How long does it take to make 10 chairs?</h3>
The total time it takes Marjorie and Blaine to perform their respective tasks in building a chair is multiplied by 10 chairs, respectively. This time is known as their speed.
The resulting figures are summed to get the total time.
<h3>Data and Calculations:</h3>
The total time it takes Marjorie to build a chair is 15 hours (1.5 hours x 10)
The total time it takes Baline to sew cushions per chair is 400 minutes (40 x 10) or 6 hours and 40 minutes.
Therefore, the total time to build 10 chairs is 21 hours, 40 minutes (15 hours + 6 hours and 40 minutes).
Thus, making 10 chairs would take Marjorie and Blaine <u>21 hours and 40 minutes</u>.

Answer:
4
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= 
where a is the first term and r the common ratio
Here r = 5 and a has to be found, thus
= 
, so
= 15624
Multiply both sides by 4
15624a = 62496 ( divide both sides by 15624
a = 4
