Answer:
3cd+3 1/3c- 3d
Step-by-step explanation:
6 cd+ 3 c- 7 d- 3 cd+ 4d+ 1/3 c
6 cd - 3 cd = 3 cd First term
3c + 1/3c = 3 1/3c Second Term
4d - 7d = -3d Third Term
Combine all terms to get:
3cd+3 1/3c- 3d
Answer:
x(3 + 4)
4(3x + 1)
Step-by-step explanation:
3x + 4x
The common factor is x, so factor out the x.
3x + 4x = x(3 + 4)
12m + 4
The common factor is 4, so factor out the 4.
12m + 4 = 4(3x + 1)
equation is g(x)=4(x-2)+7, (bit unsure of this next part) rule is g(x-2)
If the equilibrium is such that only 12000 units are sold for $27, then the total earnings from the given scenario is $324,000. The supply equation would then be,
supply: 324000 = 6p ; p = 324000/6 = 54000
demand: 324000 = 69p ; p = 324000/69 = 4695.65 ≈ 4696
Answer:
C. $97
Step-by-step explanation:
The average of his wage for all 15 days is the sum of all wages for the 15 days divided by 15.
average wage for 15 days = (sum of wages for the 15 days)/15
The amount of wages during a number of days is the product of the average wage of those days and the number of days.
First 7 days:
average wage: $87
number of days: 7
total wages in first 7 days = 7 * $87/day = $609
Last 7 days:
average wage: $92
number of days: 7
total wages in last 7 days = 7 * $92/day = $644
8th day:
wages of the 8th day is unknown, so we let x = wages of the 8th day
total wages of 15 days = (wages of first 7 days) + (wages of 8th day) + (wages of last 7 days)
total wages of 15 days = 609 + x + 644 = x + 1253
average wage for 15 days = (sum of wages for the 15 days)/15
average wage for 15 days = (x + 1253)/15
We are told the average for the 15 days is $90/day.
(x + 1253)/15 = 90
Multiply both sides by 15.
x + 1253 = 1350
Subtract 1253 from both sides.
x = 97
Answer: $97
