The order of length measurement starting with the smallest is 4.3 m, 433 cm, 4340 mm, and 0.043 km.
To compare the given measurements of length, they should have similar units. In this case, we can convert each length measurement to meter. The following conversion of different units to meter is listed below:
- 1 km = 1000 m
- 1 cm = 0.01 m or 100 cm = 1 m
- 1 mm = 0.001 m or 1000 mm = 1 m
Conversion of units to m:
- 0.043 km * (1000 m/km)= 43 m
- 433 cm * (0.01 m/cm) = 4.33 m
- 4340 mm * (0.001 m/mm)= 4.34 m
- 4.3 m
Lengths in order of size starting with the smallest:
- 4..3 m
- 433 cm or 4.33 m
- 4340 mm or 4.34 m
- 0.043 km or 43 m

6.5 gallons = 24.6052 liters
6.5 has 2 significant figures, so it would need to be 25 liters
Let us define each :
1. Natural numbers : the positive integers (whole numbers) 1, 2, 3, etc., and sometimes zero as well.
2.Whole numbers: Whole Numbers are simply the numbers 0, 1, 2, 3, 4, 5, ... (and so on)
3. Positive integers: The positive integers, z+ , consist of the whole numbers beginning with one.
4. Counting numbers: Any number you can use for counting things: 1, 2, 3, 4, 5, ... (and so on). Does not include zero.
So we can say that whole numbers is the odd one out, since it includes 0 and others dont.
Answer:
(5, 3 ) and (- 
, - 10 )
Step-by-step explanation:
Given the 2 equations
2x - y = 7 → (1)
xy = 15 → (2)
Rearrange (1) expressing y in terms of x , that is
y = 2x - 7 → (3)
Substitute y = 2x - 7 into (2)
x(2x - 7) = 15
2x² - 7x = 15 ( subtract 15 from both sides )
2x² - 7x - 15 = 0 ← in standard form
(x - 5)(2x + 3) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
2x + 3 = 0 ⇒ 2x = - 3 ⇒ x = -
Substitute these values into (3) for corresponding values of y
x = 5 : y = 2(5) - 7 = 10 - 7 = 3 ⇒ (5, 3 )
x = - : y = 2(- ) - 7 = - 3 - 7 = - 10 ⇒ (- , - 10 )
