Answer:

The solution of the given system is (5,12).

Step-by-step explanation:

Here, the given system of equations is,

3x + 2y = 39 -------(1),

5x - y = 13 ---------(2),

Equation (1) + 2 × Equation (2),

We get,

3x + 10 x = 39 + 26

13x = 65

⇒ x = 5

From equation (1),

3(5) + 2y = 39,

15 + 2y = 39

2y = 39 - 15

2y = 24

⇒ y = 12,

Hence, the solution of the given system is (5,12).

Answer is (5,12)...
3(5)+2(12) = 39

5(5) - 12 = 13

Yellowstone Lake, in Wyoming, is the largest high-altitude lake in North America, measuring 20 miles long and 14 miles wide. How

agasfer [191]

Answer:

6.67in long and 4.67in wide

Step-by-step explanation:

Given the amp of the scale 1 inch = 3 mi?

If the measured length is 20miles

Let x be the dimension of the length on the map

1 inch = 3 mi?

x = 20miles

3x = 20

x = 20/3

x = 6.67in

For the width,

Width =14miles

Let y be the dimension of the width on the map

1 inch = 3 mi

y = 14miles

3y = 14

y = 14/3

y = 4.67in

Hence the Yellowstone Lake appears 6.67in long and 4.67in wide on the Map
