This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
After 28 days she will have 200. every 28 days she saves 80 dollars and after 112 she will have saved 320. She will then be at 460 and need 40 more dollars which is 14 days, and 112 plus 14 is 126 days. Hope that helped
Answer: v=42
Step-by-step explanation:
18+(6)(4)
Answer:
Part A:
P(x)=15x^4+30x^3-50
Part B:
P(4)=$4270
Step-by-step explanation:
Part A:
In order to find the profit function P(x) we have to integrate the P'(x)
P'(x)=x(60x^2+90x)
P'(x)=60x^3+90x^2
P(x)=15x^4+30x^3+C
when x=0, C=-50
P(x)=15x^4+30x^3-50
Part B:
x=4
P(x)=15x^4+30x^3-50
P(4)=15*4^4+30*4^3-50
P(4)=$4270
Profit from selling 400 pounds is $4270
Answer:
$3.90
Step-by-step explanation:
The total cost was $24.40.
We know the cost for beads for each necklace is also $2.20, multiply this by four to find the cost of the beads for all the necklaces.
$2.20 × 4 = $8.80
Now we will subtract this from the total price.
$24.40 - $8.80 = $15.60
$15.60 Is the remaining cost for the pendants of all four necklaces. We will now divide this by four to find the price of a single pendant.
$15.60 ÷ 4 = $3.90
<u>This means the cost of each pendant is $3.90</u>
