Bella can cut about 24 pieces because you have to divide 85 feet by 3.5 feet to find out how many pieces which is 24.285 and so on but you just round to 24.
Answer:
$10452958
Step-by-step explanation:
Initial profit = $11900848
Fall rate= $48263 per year
Equation:
- P(x)= 11900848 - (x-1990)*48263,
where P(x)= profit at year of x, and 1990<x<2020
- P(2020)= 11900848- 30*48263= $10452958
Answer:
Step-by-step explanation:
-k - ( -8k + 7)
negative sign is outside the parenthesis. so it should be multiplied with -8k and 7
-k - (-8k + 7) = -k - 8k * (-1) + 7*(-1)
= -1k + 8k - 7
Now -k and 8k are like terms. So, combine them.
= 7k - 7
You will have to divide 353 millimeters by 4:
353 ÷ 4 = 88.25
now we have to multiply 88.25 by 9 (5+4), the total millimeters of only one portion of this drug
88.25 x 9 = 794.25
So he will make 794.25 millimeters of drug (that is if he has the part a too)
(If you should round 88.25 to 88, the answer would be 88 x 9 = 792)
Answer:
6 $10 bills
Step-by-step explanation:
First you have to make a system of equations like such
5x + 10y = 150
x + y = 24
Now you can use any strategy to simplify it but I'll use multiplication and the subtraction:
5x + 10y = 150 - 5x + 5y = 120 = 5y = 30 this simplified is y = 6. You then substitute 6 for y in either equation. x + 6 = 24 and make it on opposite sides. x = 18.
So 18 $5 bills and 6 $10 bills
