What equations have the same solution as 2x - 5 = 15?

a. 2x = 10
b. 2x = 20
c. 2(x - 5) = 15
d. 2x - 20 = 0
e. 4x - 10 = 30
f. 15 = 5 - 2x

B, D, E, F

Step-by-step explanation:

Once the equation 2x-5=15 is solved, the answer comes out to be 10. B has the same solution because when finding x, you divide 20 by 2 to get x=10. D is correct because you add 20 to the side with 0 to get 2x=20, then you do the same steps as you did for answer choice B to get 10. E is correct because when you add 10 to the 40 on the answer side, you get 40, 40/4=10, so x=10.F is correct because it's the same equation from the question, just backwards, x=10. A is incorrect because 10/ 2= 5, so x=5. Finally, C is incorrect because with the 2 outside of the parenthese, it is distributing to not only x but also five, making the equation 2x-10=15, making x= 12.5.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
