Mr. Brown is creating examples of systems of equations. He completes the steps to find the solution to the equation below. 5x + 2y = 8
-4(1.25x +0.5y = 2)

5x + 2y = 8
-5x - 2y = 8

0 = 0

Based on this work, what is the solution to the system?

(-4, -4)

(0, 0)

no solution

infinitely many solutions

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.

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

the answer is b

i believe it is the square root of 122 because when you turn it on it's side, to where the 5 inches is on the bottom, it looks like it is the same length.
