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.

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the correct answer is 1: 2
