Answer:
9
Solution:
Write it in an algebraic form (x is your number)
2x-11=7
Now solve
2x=7+11=18
X=18/2=9
1. Write as an algebraic equation:
12 + n ≤ 2n - 8
2. Solve for n.
12 + n - 12 ≤ 2n - 8 - 12
n ≤ 2n - 20
n - 2n ≤ 2n - 20 - 2n
-n ≤ -20
Multiply both sides by -1 (this means you must flip the inequality sign).
n ≥ 20
FINAL ANSWER: n ≥ 20
Hope this helps! Feel free to ask for clarification.
Answer:
B 10x+5
Step-by-step explanation:
:)
All we have to do is divide the distance of the old sidewalk by 3.14:
65 / 3.14 ≈ 20.7006
That means that, rounded to the nearest meter, the new sidewalk is:
21 meters long!
Answer:
The correct option is;
C diseconomies of scale; coordination problems
Step-by-step explanation:
Dis-economies of scale is in effect where the average cost of production of firm increases as it increases its inputs towards producing more. That is as the production rate increases, the unit cost of production also increases
Increase in the mean cost of production as the production rate increases is an indication of diminishing returns to increasing scale of production
Dis-economies of scale can be caused by Coordination problems
Difficulties in Co-ordination and monitoring . Where there is growth, the monitoring and coordination requirements becomes more complex, there is also the tendency for increased inefficiency and increase in average cost as the firm expands
