Answer:
X = 2
Step-by-step explanation:
He bought 2.5 pounds of apples on monday, then another 1.2 pounds on tuesday. In total, he bought 2.5+1.2 = 3.7 pounds of apples.
Multiply this with the cost per pound (2.20)
3.7*2.20 = 8.14
Answer: Choice C) $8.14
Okay so what you want to do is find the mcd or most common denomanater
to do that you want to list out the factors of 3 and 6. after you do that you should see the the mcd is 6. so now 6 is your new denamanater. so you keep 5/6 and for 2/3 you multiply the top and bottum by 2 so your new fraction is 4/6
so there isnt a correct answer to thing question
Differentiate with respect to x and y
2x +10 y y' = 0
get y' alone
y' = -2x/(10 y)
reduce
y'=-x/(5y)
continue with quotient rule of differentiation
y'' = ( 5y(-1) - (-x) (5y')) / (5y) squared
y'' = (-5y + 5xy') / (25y squared)
reduce by dividing each term by 5
y" = (-y +xy') / (5y squared) answer
Now if the teacher wants you to continue so no y or y' shows
substitute y' = -x/(5y) and y = square root ((5-x squared) / 5)
and simplify
