9/10 minis what equals 1/5?

Mathematics
1 answer:
Darya [45]3 years ago
4 0

Answer:

7/10

Step-by-step explanation:

Set up an equation to solve the problem

1/5 = 9/10 - x

Lets make them all have a common denominator

1/5 = 2/10

Subtract the 9/10

 2/10 =  9/10 - x

- 9/10   - 9/10

-7/10 = -x

Since -x equals -7/10, that means positive x equals 7/10

The answer then comes out to:

x = 7/10

Define powers provide an example of power with an exponent of 2
shtirl [24]
Well not sure what you are asking, but If it is what I think it is, it would go like this: 
          2 
(9^2)

Then the answer should be 

9^4 since we multiply the exponents. 

If you mean this...

3^2....It would be same as 3 x 3 which we should know is equal to nine. 

Hope I helped! (Be sure to thank me!)
