Step-by-step explanation:
1.I will solve your system by substitution.
−x+2y=6;6y=x+18
Step: Solve−x+2y=6for x:
−x+2y+−2y=6+−2y(Add -2y to both sides)
−x=−2y+6
[tex]\frac{-x}{-1} =\frac{-2y}{-1}[/tex] Divide by -1
x=2y−6\
Well I did this problem differently I substitute
Step: Substitute2y−6for x in6y=x+18:
6y=x+18
6y=2y−6+18
6y=2y+12
6y+−2y=2y+12+−2y
4y=12
[tex]\frac{4y}{4} =\frac{12}{4}[/tex]
y=3
Step: Substitute3 for y in x=2y−6:
x=2y−6
x=(2)(3)−6
x=0
Your final answer will be x=0 and y=3

The 7 is not a variable because variables are letters. The number seven is a coefficient because they are numbers used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients

Answers
Question:
A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?
Answer:
[tex]200 + 25x < 750[/tex]
Number of seats in a row must be less than 22
Step-by-step explanation:
Given
Total = Less than 750
Current Seats = 200
Rows = 25
Seat per row = x
Required
Represent as an inequality
The scenario will be represented as:
[tex]Current\ Seats + Rows * x = Total[/tex]
Substitute 200 for Current Seats
[tex]200 + Rows * x = Total[/tex]
Substitute 25 for Rows
[tex]200 + 25* x = Total[/tex]
[tex]200 + 25x = Total[/tex]
Substitute <750 for Total.
The equation then becomes
[tex]200 + 25x < 750[/tex]
Solving further:
[tex]25x < 750 - 200[/tex]
[tex]25x < 550[/tex]
[tex]x < \frac{550}{25}[/tex]
[tex]x < 22[/tex]
This means that:
Number of seats in a row must be less than 22

Estimate the solution of the equation a(x) = b(x)
IMAGE BELOW
Answers
Answer:
The solution of the equation a(x) = b(x) is (9, 5.5)
Step-by-step explanation:
The solution of the system of the linear equations is the common ordered pair in their solutions, this solution is the point of intersection of the lines which represent the two equations graphically
In the given figure
∵ There are two lines, the blue line, and the red line
→ Let the blue line represents a(x) and the red line represents b(x)
∵ The solution of the equation a(x) = b(x) is the point of intersection of
the two lines
∵ The x-coordinate of this point is 9
∵ The y-coordinate of this point is between 5 and 6 (5.5)
∴ The coordinates of the point of intersection are (9, 5.5)
∴ The solution of the equation a(x) = b(x) is (9, 5.5)

5 stars for a correct answer.
Answers
Answer:
12,000
Step-by-step explanation:
The two thousands that 11,900 is in between are 11,000 and 12,000 which are our two options to choose from. 11,900 is only 100 away from 12,000 and 900 away from 11,000. Because the distance between 11,900 and 12,000 is shorter than the distance between 11,900 and 11,000, this means that 12,000 would be our answer since it is closer.

Vanessa bought a laptop at a 20% discount. The original price of the laptop was $275.00. How much money did Vanessa save?
Answers
Answer:
$55.00
Step-by-step explanation:
20% of 275 is 55. Meaning she saved 55 dollars.
Answer:
Vanessa saved $55, and she only had to pay $220.
Step-by-step explanation:
First we need to convert 20% into a decimal, 0.20.
Now we need to multiply 275 and 0.20.
275 × 0.20 = 55
275 - 55 = 220
