12 feet is the answer. 4 times 3 is 12.
If you worked 19 hours per week at the cashier job, plus three hours a week doing swimming lessons, you'd be working 22 hours exactly, and making $214 per week. I hope this helps, and good luck! :)
a. The total cost is the sum of variable and fixed cost.
So the average cost of each hat is simply total cost divided by x:
ave cost = (2.12 x + 3000) / x
b. Total cost should be equal to Income:
2.12 x + 3000 = 2.75 x
Solve for x:
x = 4762 units
c. Profit is income minus total cost:
Profit = 2.75 x – (2.12 x + 3000)
1000 = 2.75x – 2.12 x – 3000
Solving for x:
<span>x = 6439 hats</span>
4n3 2m 6m 5n 2n should be written as {<span>4n^3, 2m, 6m, 5n, 2n}
4n^3 stands alone. No other term has this format.
2m and 6m are like terms and can be combined into 8m.
5n and 2n are like terms and can be combined into 7n.

Answer:
m>3 or m<-5
Step-by-step explanation:
First simplify -3m-1 < -10:
-3m < -9
m > 3 (switch direction of sign when dividing by negative number)
Then simplify -4+2m<-14:
2m<-10
m<-5
m>3 or m<-5
