1/4 + 1/2 + x = −3/4 solve for x. (1/4 is one fourth, 1/2 is one half, -3/4 is negative three fourths)

1/4 + 1/2 + x = −3/4

get a common denominator 1/4

1/4 +2/4 +x = -3/4

combine like terms

3/4 +x =-3/4

subtract 3/4 from each side

x = -3/4 -3/4

x = -6/4

divide top and bottom by 2

x = -3/2

x = -1   1/2

Answer : x = -1  1/2

x = -7/4

Step-by-step explanation:

Identify the LCD (it is 4) and mult. all terms of the given equation by it:

1 + 2 + 4x = -3

Then:   4x = -3 -2 -1, or 4x = -7.  Therefore, x = -7/4.

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.

they disappear if your absent from to long. i found out that the hard way.

brainliest lol i just need one more brainliest.
