For this case we have the following equation:
We must solve the equation by following the steps below:
We subtract 1 from both sides of the equation:
On the right side of the equation we have that different signs are subtracted and the sign of the major is placed:
We add x to both sides of the equation:
We divide between 4 on both sides of the equation:
Thus, the correct option is option B

Answer:
216°
Step-by-step explanation:
The ratio of the sum of smallest and largest to the total of all angles is ...
(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4
__
The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...
180°(5 -2) = 540°
Then the sum of smallest and largest angles is ...
0.4(540°) = 216°
Answer:
2.5 days
Step-by-step explanation:
The planned production rate was ...
(4500 dresses)/(25 days) = 180 dresses/day
The actual production rate was ...
180 dresses/day + 20 dresses/day = 200 dresses/day
So the actual time required for production of 4500 dresses was ...
(4500 dresses)/(200 dresses/day) = 22.5 days
That is the time required was less by ...
25 days -22.5 days = 2.5 days
The company finished 2.5 days early.
