Step-by-step explanation:

<h3>Given </h3>

Equations

5x+2y=7
x+y=5

The value of 4x + y

<h3>Solution</h3>

<u>Subtract the second equation from the first one side-by-side:</u>

5x + 2y - (x+ y) = 7 - 5
5x - x + 2y - y = 2
4x + y = 2

The answer is 2

1) Multiply the length value by 100,000.

$2.5 \: hm = 2.5 \times 100000$

$= >2.5 \: hm = 250000 \: mm$

2) For this, divide the length value by 1000.

$= > \frac{1800}{1000}$

$= > 1.8 \: dam$

3) For finding the approximate value, just multiply the value of length by 1.609.

$= >6450 \: m = (6450 \times 1.609) \: km$

$= > 10380.27 \: km$

4) Multiply the given mass value by 100.

$= > 1.2 \: kg = 1.2 \times 100$

$= > 1200 \: g$

5) Multiply the given value by 10,000.

$4.37 \: dag = 4.37 \times 10000$

$= > 43700 \: mg$
