Jonathan found that the correct equation -2|8-x|-6=-12 had two possible solutions: x=5 and x=-11. which explains whether his solutions are correct?
a) he is correct because both solutions satisfy the equation.
b) he is not correct because he made a sign error.
c) he is not correct because there are no solutions.
d) he is not correct because there is only one solution: x=5

D

Step-by-step explanation:

Check the solutions by substituting the values of x into the left side of the equation and if equal to the right side then they are a solution.

x = 5

- 2 | 8 - 5 | - 6 = - 2 | 3 | - 6 = (- 2 × 3) - 6 = - 6 - 6 = - 12 ← correct

x = - 11

- 2 | 8 + 11 | - 6 = - 2 | 19 | - 6 = (- 2 × 19) - 6 = - 38 - 6 = - 44 ≠ - 12

Thus x = 5 is a solution but x = - 11 is not → D

The solutions to the equation are in fact x = 5 and x = 11

Step-by-step explanation:

if you want to find the solutions here is a method:

-2|8-x|-6=-12

divid by -2 :

|8-x|+3=6

|8-x| = 3

8-x = 3 or 8-x=-3

x= 5 or x=11

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
