Answers are in bold:
-1=3x-2
add 2 to both sides
-1+2=3x-2+2
1=3x
divide both sides by 3
1÷3=3x÷3
1/3=x
-3x=9
divide both sides by -3
-3x÷-3=9÷-3
x=-3
-10=-5x
divide both sides by -5
-10÷-5=-5x÷-5
2=x
I hope this is good enough:
Answer:
(C) 18
Step-by-step explanation:
We can create a systems of equations. Assuming
is Michelle's age,
is Joan's age, and
is Ryan's age, the equations are:



We can use substitution, since we know the "values" of m and j.


So we know that Joan is 18 years old.
Hope this helped!
Answer:


Step-by-step explanation:
Consider the provided number.
We need to find the approximate value of
to the nearest hundredth.
First find two perfect squares that the irrational number falls between.

118 is lying between 100 and 121, therefore the square root value of 118 will be somewhere between 10 and 11.


118 is closer to 121 as compare to 100.
Therefore, 
Consider the number 
First find two perfect squares that the irrational number falls between.

319 is lying between 289 and 324, therefore the square root value of 319 will be somewhere between 17 and 18.


319 is closer to 324 as compare to 289.
Therefore,
