Answer:
B) 10x + 8y ≥ 210
Step-by-step explanation:
We know that we have to sit at least 210 people which means that we can fit more than 210, but no less than 210. This gives us a first step in solving since we know that the equation must be greater than or equal ( ≥) 210
This rules out C & D immediately.
Now we know that circular tables can sit 10 people and are represented by the variable x which means that each circular table will be equal to 10x and that rectangular tables are denoted by y and can sit 8 people making it recognizable by 8y. We know that the people sitting at all of the tables will be added up to give us a number of either 210 or more.
The only answer that gives us the tables and how many people they seat accurately is B since it is 10x and 8y. We also see that these two numbers are added together to make it greater than or equal to 210.
Answer:
Point B would be at 5.
Step-by-step explanation:
Given segment AC in which point A is at -3 and point C at 7, representing this on the number line shows that there are 10 points from A to C.
-3 -2 -1 0 1 2 3 4 5 6 7
A C
Since the segment AC is to be divided into a ratio 4:1, then moving from point A to B (at point 5) would be the required point. Therefore, point B that would divide segment AC in ratio 4:1 is at 5.
Thus, A is at -3, B is at 5, and C is at 7.

Answer:
∠U = 26°
∠V = 35°
∠W = 119°
Step-by-step explanation:
Given:
∠U = (x+9)°
∠V = (2x+1)°
∠W = (7x)°
Find:
Value of each angle
Computation:
Using angle sum property
∠U + ∠V + ∠W = 180°
(x+9)° + (2x+1)° + (7x)° = 180°
10x + 10 = 180
x = 17
So,
∠U = (x+9)° = 17 + 9 = 26°
∠V = (2x+1)° = 34 + 1 = 35°
∠W = (7x)° = 7 x 17 = 119°
Answer:
159
