Which expression is equivalent to 4^5x4^-2
Ivan

Answer:

4^3

Step-by-step explanation:

When you are multiplying exponents with the same base (for this problem the base is 4) you add together the exponents. It is kinda hard to explain but that is just a rule you can use. So, 4^(5+(-2))=4^3

irina1246 [14]
Hello! I can help you with this! So, Mami Kudo ran 255.303 kilometers in 24 hours. I’m guessing that we have to find the answer in kilometers per hour. 255.303/24 is 10.6376 and other numbers or 10.64 when rounded to the nearest hundredth. Mami Kudo’s average speed was about 10.64 kilometers per hour.

How to solve ×+6y=13. 2×+y=15
saul85 [17]

Answer:

x, y = 7, 1

Step-by-step explanation:

x+6y=13 ............ (i)

2x+y=15 ........... (ii)

We will apply substitute method.

From equation (i), we can get,

x+6y=13

or, x = 13 - 6y .......... (iii)

Putting the value of x in equation (ii), we can get,

2x+y=15

or, 2 × (13 - 6y) + y = 15

or, 26 - 12 y + y = 15 [multiplying]

or, -11 y = 15 - 26 [Subtracting 26 from both the sides]

or, -11 y = -11

or, [(-11 y) ÷ (-11)] = [(-11) ÷ (-11)] [Dividing both the sides by -11]

or, y = 1

Therefore, the value of y = 1

Putting y = 1 in equation (iii), we get,

x = 13 - 6y

or, x = 13 - 6 × 1

or, x = 13 - 6

or, x = 7

Therefore, the value of x = 7.

Answer: x, y = 7, 1
