25 pts + brainliest for the first correct answer. find the value of x. i just need these answered quickly if possible : )

29) x = 17

30) x =14

31) x = 23

32) x = 44

Step-by-step explanation:

29)

6x - 17 = 85

6x = 102

x = 17

30)

4x + 21 + 103 = 180

4x + 124 = 180

4x = 56

x = 14

31)

2x + 23 = 4x - 23

-2x = - 46

 x = 23

32)

4x - 42 = 134

4x = 176

x =  44

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.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
