four glasses of milk and 3 snack bars have a total of 74 carbohydrates(carbs), and 2 glasses of milk and 4 snack bars have a total of 62 carbs. determine how many carbs are in 1 glass of milk and in one snack bar

21 calories

Step-by-step explanation:

Lets say the glasses of milk is defined by the variable "g". And the snack bars are defined by the variable "s".

Your equation, based off of the information given should be this:

4g + 3s = 74

2g + 4s = 62

Now you have a set of equations. Now combine.

4g + 3s = 74

-2(2g + 4s) = 62(-2)

4g + 3s = 74

-4g - 8s = -124

-5s = -50

-5s/-5 = -50/-5

s = 10

So now that you know how much one snack bar contains (10 cal) then substitute this info in one of the equations:

2g + 4(10) = 62

2g + 40 = 62

2g = 22

g = 11

Therefore one glass of milk has 11 cal and one snack bar has 10 cal. in total, 21 calories.

apex answer

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
