Answer:
7
Step-by-step explanation:
first, we would set up an equation. let 3x-4 represent "four less than a number tripled". "a number" would be represented by x. let x+10 represent "the same number increased by 10".
set 3x-4 and x+10 equal to each other:
3x-4=x+10
next, we would solve this equation for x. first we would get the x together on one side of the equation. we would do this by subtracting x from both sides to remove it from the right side of the equation:
2x-4=10
then, we would get the 2x by itself. we would do this by adding 4 to both sides:
2x=14
finally, we would divide each side of the equation by 2 to find x:
x=7.
The number is 7.
Answer:
K still the same value
Step-by-step explanation:
given a reaction aA+bB<->cC+dD the constant K is defined as:
K is a constant so it won't change the value. Instead, the values of C and D are going to change. The position of equilibrium moves because of the need to keep a constant value for the equilibrium constant.
Any set of 3 points is "coplanar".
You want to find the time <em>t</em> such that
Divide both sides by $200 :
Take the logarithm of both sides:
Divide both sides by 0.04 and solve for <em>t</em> :
