Answer:
The painting is 
Step-by-step explanation:
From the question we are told that
The amount of carbon present after t year is
{Note ; This is the function }
Here 
is the amount of carbon-14 after time t
the original amount of carbon-14
Now given that the paint as at now contain 27% of the original carbon-14
Then it mean that
So the equation is represented as
=> 
=> 
=> 
=> 
=> 
Just add the numbers in front of variables if the variables are the same!
2) 5x+7+2x=7x+7 Because you would add the 5 and 2, and since the 7 doesn't have a variable you add it onto the end.
3) 16+4p (13p-9p is 4p)
4) y^2 + 5y (you can't combine y^2 with a y variable because it has a different exponent! if there is no exponent shown it is assumed to be 1. If exponents are the same you combine them, but if not you leave it as is)
5) You distribute the 5 (multiply) with 2h and 3, leaving 10h+15+3h which is 13h+15
6) 19+4n (12+7 is 19, and 18n-14n is 4n)
7) Distribute the 2 to get 18+10k
8) Distribute the 5 to get 15m+10
9) Distribute the 6 to get 6g+6h (you can't combine these because they are different variables)
10) The GCF of 4 and 8 is 4. Place the 4 out of the parentheses. Divide 4d and 8 by four and place them inside the parentheses. 4d is 4 times d so if you divide 4 by 4 you're left with 1d or just d. 8 divided by four is two. 4(d+2)
11) GCF= 7 so 7(3p+5q)
12) GCF= 9 so 9(2x+y)

Answer:
6 for $37.50 has the same price
Step-by-step explanation:
The price per wand is found by dividing the price by the number of wands.
8 for $50 ⇒ $50/8 = $6.25 per wand
__
4 for $20 ⇒ $20/4 = $5.00 per wand <em>not the same</em>
6 for $37.50 ⇒ $37.50/6 = $6.25 per wand <em>is the same price</em>
10 for $65 ⇒ $65/10 = $6.50 per wand <em>not the same</em>
So basically what you need here first is to find the disciple and reverse it, then you will have your answer.
Answer:
80%
Step-by-step explanation:
Given:
Team D used a recipe that consists of 20 cups of sand, 2 cups of flour, and 3 cups of water.
Question asked:
How does the percent of sand in Team D's recipe compare to that of the other teams ?
Solution:
Team D used a recipe that consists of sand = 20 cups
Team D used a recipe that consists of flour = 2 cups
Team D used a recipe that consists of water = 3 cups
Total number of cups together = 20 + 2+ 3 =25 cups
Now we will have to find percent of cups of sand out of the total number of cups.
By using formula of percentage,
Percent = 
Therefore, 80% of sand in Team D's recipe compare to that of the other teams.
