For a National Junior Honor Society Induction Celebration, Ahmed is renting tables and chairs. He wants to have only tables for 4 and tables for 6. The total number of people that can be seated in the school cafeteria with these tables is 160.
Write an equation to represent the situation. Let x represent the number of 4 seat tables and y represent the number of 6 seat tables.
Answer:
There are different combinations you can do.... for example
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
so Im not sure which :/ but the equation would be:
10x+20y=160
or
25x+10y=160
there are different combinations of the two so im not sure T_T
This question is based on the concept of linear equation. Therefore, the equation would be, 10x+20y=160 or 25x+10y=160 to represent the situation.
Given:
He wants to have only tables for 4 and tables for 6. The total number of tables is 160.
And x represent the number of 4 seat tables and y represent the number of 6 seat tables.
We need to determined an equation to represent the situation.
Let x represent the number of 4 seat tables and y represent the number of 6 seat tables.
According to the question,
There are different combinations we can make as below,
For example :
10 tables of 4 and 20 tables of 6
or
25 tables of 4 and 10 tables of 6
Therefore, the equation would be, 10x+20y=160 or 25x+10y=160 to represent the situation.

Answer:
a) 8
b) -4
c) 3x² - 4x + 8
d) 20
e) 28
Step-by-step explanation:
a) (-2)² + 4 = 8
b) 8 + [4(-2) - 4] = 8 + (-8 - 4) = 8 + (-12) = -4
c) 3(x² + 4) = 3x² + 12
3x² + 12 - (4x - 4) = 3x² - 4x + 8
d) g(2) = 4 4² + 4 = 20

Answer:
n= -4/7
Step-by-step explanation:
what is the least common dominator of 3/4 4/5 and 2/3
Prove: The sum of two multiples of 3
is a multiple of 3.
3m + 3n = [?](m + n)
= a multiple of
Just factor out the 3:
3m + 3n = 3 (m + n)
so if x +3y =1 how do i plug it in to -x +2y =4
-x +3y=1-x
3y/3=1-x/3
y=1/3 - x/3
y=-1/3x +1/3
Then I have to plug x into the y= the fractions confuse me
If x + 3y = 1, then x = 1 - 3y.
Then in the second equation, replace x with 1 - 3y :
-x + 2y = 4
- (1 - 3y) + 2y = 4
-1 + 3y + 2y = 4
-1 + 5y = 4
5y = 5
y = 1 → x = -2
since x = 1 - 3•1 = 1 - 3 = -2.
Alternatively, you can instead solve for y in the first equation, so that if x + 3y = 1, you get
x + 3y = 1
3y = 1 - x
y = (1 - x)/3
Then replace y in the second equation:
-x + 2y = 4
-x + 2 ((1 - x)/3) = 4
-x + 2/3 (1 - x) = 4
Multiply both sides by 3 to get rid of the fraction:
-3x + 2 (1 - x) = 12
-3x + 2 - 2x = 12
-5x + 2 = 12
-5x = 10
x = -2 → y = 1
since y = (1 - (-2))/3 = (1 + 2)/3 = 3/3 = 1.
