I'm very sorry, but there is no questions 21-23, if you give me the picture, I'll do it.
Step-by-step explanation:
Divide across and see if its proportional meaning that is the same... The answer is 2 so its proportional Hope this helped Im not good at Math but i do understand this i learned it a few days ago Im not a professional though lol I just know how to do this stuff and percents a percent over 100 and X over the number if you ever need help there just like Fractions message me i know how to do proportional relationships Ill try..
Answer:
y' = (2x + y cosxy)/(2y + x cosxy)
Step-by-step explanation:
Using implicit differentiation:
y^2 = x^2 + sin xy
2y y' = 2x + cos xy * (xy' + y)
2y y' = 2x + xy' cos xy + y cos xy
2y y' - xy' cosxy = 2x + ycos xy
y' = (2x + y cosxy)/(2y - x cosxy)
15/5 = 3
Flour = 3/8 x 3 = 9/8 = 1 1/8 cups.
Chocolate chips = 1/2 x 3= 3/2 = 1 1/2 cups.
Butter = 4/5 x 3 = 12/5 = 2 2/5 cups.
Teaspoons of salt = 4/16 = 1/4 = 1/4 x 3 = 3/4
Earthworms = 1.5 = 3/2 x 3 = 9/2 = 4 1/2 cups.
