Answer:
12n+9=93
solve for n
12n=93-9
n=84/12
n=7
therefore, Mr. copper bought 7 tickets.
im not really sure about this since i think you can just stop at equation 1
10/14 divided by 2 = <span>0.35714285714</span>
Solution : |x+3| =7
or x= -10 or x=4
Explanation:
•You are basically looking for 2 values of X
•First X will be to the left of -3
•Second X will be to the right of -3
•Both X’s will be 7 units away from -3, if you do this correctly you will find that x to the left is equal to -10 and x to the right is equal to 4
You can develop the absolute value equation as follows:
X=-3 -7
Or
X=-3+7
Add 3 to both sides of the equation to get :
X+3=7
X+3=-7
This fits the basic definition of an absolute value equation that states if |x|=y , then x=y or x=-y
