Answer:
x=2.5
Step-by-step explanation
move right x to other side by subtracting 3x on both sides.
now you should have 2x=5
make the x be by itself by dividing 2 on both sides
x=2.5

Step 1
Find out how many chairs are already taken. Multiply the tables by the chairs

Step 2
By using proportion find the percentage

therefore
the answer is

X/3 = x + 2/5....multiply everything by common denominator of 15
5x = 15x + 6
5x - 15x = 6
-10x = 6
x = -6/10 reduces to - 3/5
or...
x/3 is the same as 1/3x
1/3x = x + 2/5
1/3x - x = 2/5
1/3x - 3/3x = 2/5
-2/3x = 2/5
x = 2/5 * -3/2
x = - 6/10 which reduces to - 3/5
Answer:
6√3 or 10.39 to the nearest hundredth.
Step-by-step explanation:
3 radical 12
I assume you mean 3 * √12
this simplifies to
3 * √4 * √3
= 3*2*√3
= 6√3 or 10.39 to the nearest hundredth.
