Answer:

He can buy 4 model cars

Step-by-step explanation:

∵ His total money = the cost of books + the cost of model cars

∵ He buys 6 books and the price of each book is $2

∵ The cost of each model car is $7 , let the number of model cars is c

∵ He has $40

∴ 6 × 2 + 7 × c = 40

∴12 + 7c = 40

∴ 7c = 40 - 12 = 28

∴ c = 28/7 = 4

∴ He can buy 4 model cars

It would help if you find common denominator... 12
so 1/3 times 4 both the numerator and denominator
4/12

and 3/4 times by 3 both the numerator and denominator
9/12

the recipe calls for 4/12 cup of oil and you have 9/12

two batches would be 8/12 cups of oil, you have 9/12 that is just enough for the recipe for two batches...

now to simplify it again, 1/3 + 1/3 = 2/3 and 2/3 is less than 3/4 
the answer would be the upper right

Find dy/dx by implicit differentiation and evaluate the derivative at the given point.xy = 12, (-4, -3)
mojhsa [17]
Xy=12
xdy/dx + y = 12
xdy/dx = 12 - y
dy/dx= (12-y) /x
dy/dx | x=-4 ,y=-3 = (12-(-3))/(-4)
= (12+3)/-4 = -15/4
