The answer is 9
sqrt(49) = 7
4^2 = 16
16-7 = 9
Answer:
<h2>
4.5</h2>
Step-by-step explanation:
![x \times 2 + 1 = 10](https://tex.z-dn.net/?f=x%20%5Ctimes%202%20%2B%201%20%3D%2010)
![2x + 1 = 10](https://tex.z-dn.net/?f=2x%20%2B%20%201%20%3D%2010)
Move constant to R.H.S and change its sign
![2x = 10 - 1](https://tex.z-dn.net/?f=2x%20%3D%2010%20-%201)
Subtract the numbers
![2x = 9](https://tex.z-dn.net/?f=2x%20%3D%209)
Divide both sides of the equation by 2
![\frac{2x}{2} = \frac{9}{2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B2x%7D%7B2%7D%20%20%3D%20%20%5Cfrac%7B9%7D%7B2%7D%20)
Calculate
![x = 4.5](https://tex.z-dn.net/?f=x%20%3D%204.5)
Hope this helps..

Answer:
guys just be like dat
Step-by-step explanation:
Remember, in order for this equation to be true either one of the polynomials has to equal 0
So:
-> x+6 = 0
x=-6
-> 2x-5 = 0
2x= 5
x= 5/2
So the answer is x=-6 and x= 5/2.
Hope this helps!
The probability of drawing a 5 from card numbered 1 - 10 is 1/10 because only one card out of ten is numbered 5.
The probability of rolling a 2 on the cube is 1/6 because there are 6 faces of the cube with 6 different numbers. The probability of picking a 5 and rolling a 2 together is 1/60 because
1/10 x 1/6 = 1/60. You multiply them together because there will be 60 combinations: 10 card possibilities and 6 cube possibilities.
Hope this helps!
