Two glasses of milk and 3 snack bars have a total of 63 carbohydrates​ (carbs), and 4 glasses of milk and 2 snack bars have a total of 82 carbs. Determine how many carbs are in one glass of milk and in one snack bar.

Answers

Answer:

Glass of milk=15 carbs

One snack bar=11 carbs

Step-by-step explanation:

×2 2m+3s=63.......................1

×1 4m+2s=82..............2

4m+6s=126

4m+2s=82

Cancel out the 4ms

6s=126

2s=82

minus top and bottom equations and remain with

4s= 44

s=44/4

s=11 ∴ one snack bar is 11 carbs

subs s=11 into equation 1

2m+3s=63

2m+3(11)=63

2m+33=63

2m=63-33

2m=30

m=30/2

m=15  ∴one glass of milk is 15 carbs

14. Two sides of a parallelogram are in the ratio 5 : 3 and its perimeter is 48 cm. Find
the length of each of its sides.​

Answers

Answer :-

Given :-

Ratio of two Sides of Parallelogram ( Length and breadth) = 5 : 3

Perimeter of the parallelogram = 48cm

To Find :-

Length of each side of the parallelogram

Formula :-

Perimeter of the parallelogram = 2( length + breadth)

Solution :-

Let the length and breadth be 5x and 3x

2(5x + 3x) = 48cm

2(8x) = 48cm

x = 48/16

x = 3cm

Length = 5x = 5×3cm = 15cm

Breadth = 3x = 3×3cm = 9cm

We know that,

In parallelogram Opposite sides are equal

Hence, The sides of the Parallelogram are 15cm, 9cm, 15cm and 9cm
