3(5-2x) = 2(4x=3)
= 15-6x = 8x=6
= 15-6x = 8x-6
= 15-6 = 8x+6x
= 9 = 14x
therefore, x=9/14

A square table can seat 4 people,
How many square tables are needed to seat 26 people if the tables are pul
together?
Hint:
2 tables con seot 6 people.
1 table can seat 4 people.
Answer:
13 tables
Step-by-step explanation:
If 1 table can seat 4 people and 2 tables can seat 6 people.
That means that the pattern is +2.
26/2 = 13
That means 13 tables are needed to seat 26 people.
Im not sure if this is correct...
For 26 people 12 tables will be needed.
What are number series?A number series is a number-based sequence. We will need to identify the rules that lead to the formation of a number series for the number series questions. A series is, roughly speaking, a description of the process of adding infinitely many quantities, one after the other, to a given starting quantity. Calculus and its generalization, mathematical analysis, include a significant portion of the study of series. Even when studying structures that are finite, series are utilized in most areas of mathematics.
Given A square table can seat 4 people
and 2 tables can seat 6 people,
tables needed for 26 people let be n
according to condition arrangement is explained in figure
let n tables are kept together and 26 people sit together in long table
1 + n + n + 1 = 26
2n + 2 = 26
2n = 26 - 2
2n = 24
n = 12
Hence 12 tables required for 26 members.

Given that a function, g, has a domain of -20 ≤ x ≤ 5 and a range of -5 ≤ g(x) ≤ 45 and that g(0) = -2 and g(-9) = 6, select the statement that could be true for g. A. g(-4) = -11 B. g(7) = -1 C. g(-13) = 20 D. g(0) = 2
Answer:
C
Step-by-step explanation:
C can be true, because -13 is inside the defined domain, and 20 is inside the defined range.
A cannot be true, because -11 is outside of the defined range.
B cannot be true, because 7 is outside of the defined domain.
D cannot be true, because g(0) has already a different assigned result value : -2. and in a function no x can have multiple assigned result values.
