Answer:
x =
, x = ![\frac{-3}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B-3%7D%7B7%7D)
Step-by-step explanation:
The first step is to get rid of the square on the x, and to get rid of it, you square root both sides of the equation, like so:
![x^{2} = \frac{9}{49}](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D%20%5Cfrac%7B9%7D%7B49%7D)
![\sqrt{x^2} = \sqrt{\frac{9}{49} }](https://tex.z-dn.net/?f=%5Csqrt%7Bx%5E2%7D%20%3D%20%5Csqrt%7B%5Cfrac%7B9%7D%7B49%7D%20%7D)
A perfect square is when a number has two factors that are identical to one another. In this case, 9 and 49 are both perfect squares, meaning we can break them down:
The square root of 9 is 3. (3 · 3 = 9)
The square root of 49 is 7. (7 · 7 = 49)
x = ![\frac{3}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B7%7D)
The answer is also x =
because a negative · a negative = a positive.
Hello!

and anything times 0 is always 0
I hope this helps, and have a fantastic day!
Answer:
Step-by-step explanation:
The common denominator of these 2 fractions is 10.
Turn the mixed number 3 4/5 into an improper fraction which would be
19/5.
Then multiply the numerator and denominator with 2 to get the denominator to be 10.
19/5 x 2 = 38/10
Now turn 2 1/10 into an improper fraction= 21/10
Now subtract...
38/10 - 21/10 = 17/10
So Timberly spent 17/10 or 1 7/10 more hours then Misty at the gymnastics practice
