A chemical compound requires 8 ounces of chemical A and 12 ounces of chemical B. A mixture contains 24 ounces of chemical A and 30 ounces of chemical B. How can you fix the mixture to make the chemical compound?
Answers
I might always be wrong.
Explanation:
Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B.
Take 1/3 of the total mixture to have 8oz of chemical A and 12oz of chemical B.

find the measure of each angle indicated and please explain how you got that answer if you can
Answers
In the photo I included, both points A and B are equal, because they are intersecting. To get the measurement for these angles, you add 40+40 to get 80. We know that three angles in a triangle need to add up to 180, so you would subtract 80 to get 100. If point A and B are 100, that means you can add 100+45 to get 145, and subtract that from 180 to get your answer. (35)
#16- The answer should be 42. Using the same logic as before, take away 80+40 from 180 to get 60 for points A and B. Then you would subtract 78+60 from 180 to get your answer. (42)
#17- The answer should be 108. You need to find the final angle of the triangle by subtracting 37+71 from 180. This would equal 72. Since the angle of a line is 180 degrees, you would subtract 72 from 180 to get the finished product. (108)
#18- The answer should be 35. You would start by finding the bottom left angle. You would use the same logic as I did in #17 by subtracting 180-126. This tells you that the bottom left angle in the triangle is 54. Then you would subtract 91+54 from 180 to get your answer. (35)
I hope this helps and that it wasn’t too confusing. #17 and #18 aren’t my strong suit, so I’m sorry if I’m wrong. Please mark brainliest!
During the economic downturn in 2008, the price of a stock, A(x), over an 18-month period decreased and then
increased according to the equation A(x) = 0.70x2 - 6x + 15, where x equals the number of months. The price of
another stock, B(x), increased according to the equation B(x) = 2.75x + 1.50 over the same 18-month period. State all

Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?
Answers
Answer:
Kylie is 24 years old
Step-by-step explanation:
kylie = x
Bobby=x-5
x+x-5=43
2x-5=43
2x=43+5
2x=48
X=24 years old
19
If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

Mr. Sanchez’s class sold fruit pies for $1.65 each and Mr. Kelly’s class sold bottles of fruit juice for $1.36 each. Together, the classes sold 79 items and earned $118.17 for their school.
(a) Write and solve a system of equations that model the problem. Show all your work.
(b) Which class earned more money?
(c) How much more money did that class earn?
Answers
Answer:
Step-by-step explanation:(a)
1.65p+1.36j=118.17 and p+j=79
We can say p=79-j and sub this value in first equation
1.65(79-j)+1.36j=118.17
130.35-1.65j+1.36j=118.17
-0.29=-12.18
j=42, p=79-j, p=79-42=37
(b)
1.65(37)=61.05 and 1.36(42)=57.12
Sanchez class earned more selling pies.
(c)
61.05-57.12=3.93
So Sanchez class made $3.93 more than Kelley class.

It takes 3.5 cups of pancake mix and 2.625 cups of water to make 21 pancakes.
Step-by-step explain
First divide each by 6 to figure out how much mix and water it takes to make one pancake
1/6 mix + .125 cups water = 1 pancake
Multiple each by 21 to know how much mix and water it takes to make 21 pancakes
3.5 mix + 2.625 water = 21 pancakes
Answer:
15 3/4
Step-by-step explanation:
you multiply 3/4 times 21 then you will get 3/4 times 21/1 and the answer is 63/4 and simplify and get 15 and 3/4.

W-20.5=8 please help me
Answers
This is just the same as asking you what number when subtracted by 20.5 will give you an answer of 8. The answer would obviously be 8+20.5=28.5 so w=28.5.
We can also do it in a more algebraic way. By adding 20.5 to both side of the equation which won't change the value.
w-20.5+20.5=8+20.5
w=28.5
