Answer:
Equation: x + 16 + 13 + x = 21 ; x = -4
Step-by-step explanation:
x + 16 + 13 + x = 21 (Given)
2x + 29 = 21 (Added like terms)
2x = -8 (Subtracted 29 on both sides)
x = -4 (Divided 2 on both sides)
Answer:
(B) There are 12 glasses for every 1 table
Step-by-step explanation:
Since the graph is a perfectly straight line, we can assume that there is a proportional relationship. Looking at the axes confirms this. For the 1st table, there are 12 glasses, for the 2nd, there are 24, and so on.
So, we can see that the proportion between tables and glasses is 12:1. For every 1 table, 12 glasses must be placed on it.
So, if they gave this to you as a table or a formula, you'd simply need to multiply 12 by the number of tables to see how many glasses are required.
