Four glasses of milk and 2 snack bars have a total of 72 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a t

Travka [436]

One glass of milk has 11 carbs and one snack bar has 14 carbs.

Step-by-step explanation:

Let,

Glass of milk = x

Snack bar = y

According to given statement;

4x+2y=72 Eqn 1

2x+3y=64 Eqn 2

Multiplying Eqn 2 by 2

$2(2x+3y=64)\\4x+6y=128\ \ \ Eqn\ 3$

Subtracting Eqn 1 from Eqn 3

$(4x+6y)-(4x+2y)=128-72\\4x+6y-4x-2y=56\\4y=56$

Dividing both sides by 4

$\frac{4y}{4}=\frac{56}{4}\\y=14$

Putting y=14 in Eqn 1

$4x+2(14)=72\\4x+28=72\\4x=72-28\\4x=44$

Dividing both sides by 4

$\frac{4x}{4}=\frac{44}{4}\\x=11$

One glass of milk has 11 carbs and one snack bar has 14 carbs.

Can Someone Please Help Me Factor (x^(2)+6x+58)

maxonik [38]

The last term is 58. List out the ways to multiply two whole numbers to get to 58

1*58 = 58
2*29 = 58
(-1)*(-58) = 58
(-2)*(-29) =58

Then go through those factors and see which two values add to 6 (which is the middle number in the given expression)

1+58 = 59
2+29 = 31
-1+(-58) = -59
-2+(-29) = -31

None of those sums are 6, so the original expression cannot be factored. It is said to be prime.
