For this case we have the following expression:

By definition of division of powers of the same base, we have to place the same base and subtract the exponents, that is:

So:

b

Step-by-step explanation:

You need to remember a property called "Quotient of powers property". This property states the following:

You can observe that the bases of the expression are equal, then you can apply the property mentioned before.

Therefore, you can make the division indicated in the exercise.

Then you get this result:

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

-7 -7

2x is greater than 10

divide by 2 each side

x is greater than 5
