Answer:

Option: A is the correct answer.

( A. Division)

Step-by-step explanation:

We know that the speed of a person ;if a person travels 10 km in 1 hour is given as:

10 Kilometer per hour ( km/hr).

Since, the speed is defined as:

$Speed=\dfrac{Distance}{Time}$

( so, the speed is the ratio of distance to time i.e. we can say that distance divided by time)

So, the unit All per-unit concepts rely on ratios, meaning division.

4x - 2x + 8 = 6(x + 4) Given

(4x - 2x) + 8 = 6(x + 4)

2x + 8 = 6(x + 4) Combine like terms

2x + 8 = (6)(x) + (6)(4)

2x + 8 = 6x + 24 Distributive Property

2x - 6x + 8 = 6x - 6x + 24

-4x + 8 = 24 Subtraction Property of Equality

-4x + 8 - 8 = 24 - 8

-4x = 16 Subtraction Property of Equality

-4x : (-4) = 16 : (-4)

x = -4 Division Property of Equality

Help me please please

When dividing same numbers with different exponents (they’re both 10 so this works different than if they were different numbers) you subtract the top exponent by the bottom exponent. So 15-4=11 ultimately making the solution 10^11. Hope this helps :)
