Answer:
Step-by-step explanation:
We have given number of full tables = 17 tables
Number of empty tables =3 tables
Total number of tables =17+3=20 tables
We have to find the ratio of empty tables to the ratio of full tables
So the ratio of empty tables to full tables 
here nominator is the number of empty tables and denominator is number of full tables
Area = 1/2*base*height
= 1/2*4.8*5.2
= 2.4*5.2
= 12.48units
All you do is solve for z. So 8z-13=7. To solve for a variable you have to do the opposite to cancel out the numbers on each side. First you add 13 over to 7 to cancel out 13 on the z side. So 8z=20 is what you have left. Then you divide 8 on both sides to cancel out 8 on the z side. what you are left with is z=2.5. Lastly you plug and check. 8(2.5) - 13 = 7, 20-13=7. And thats correct so z is 2.5.
