Answer:
x=-7
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
40 + x+57 + 90 =180
Combine like terms
187 +x = 180
Subtract 187 from each side
187-187 +x = 180-187
x = -7
Answer:
I don't think I know it sorry
(a) The profit when the company sold 1000 pens is -1000.
(b) The number of pens that are required to sell in the break-even is 1167.
(a)
The profit when the company sold 1000 pens is
P = R - C
= 9x - (3x + 7000)
= (9 × 1000) - (3 × 1000 + 7000)
= 9000 - (3000 + 7000)
= 9000 - 10000
= -1000
(b)
The number of pens that are required to sell in the break-even is
R = C
9x = 3x + 7000
9x - 3x = 7000
6x = 7000
x = 1167
Therefore we can conclude that:
(a) The profit when the company sold 1000 pens is -1000.
(b) The number of pens that are required to sell in the break-even is 1167.
