I am trying to find what x and y means please help
5x + y = 7
Answer:
X and Y are variables.
Consider that you have $7. It costs $5 to buy a sandwich and $1 to buy a drink.
To find out what you can buy, and spend $7 (on the nose), we have the formula
5X + 1Y = 7
Answer:
x=1 y=

Find the values of x and y
Answer:
x = 8
y = 21
Step-by-step explanation:
The angle (7x + 12)° and the angle (12x-28)° are alternate interior angles and so has got the same measurement
7x + 12 = 12x - 28
12 + 28 = 12x - 7x
40 = 5x divide both sides by 5
8 = x
The sum of angle (12x - 28)° and (9y - 77)° must be equal because they make a straight line with the measure of 180°
12x - 28 + 9y - 77 = 180 we already found the value of x as 8 so let's rewrite the equation
12 × 8 - 28 + 9y - 77 = 180
96 - 28 - 77 = 180 add like terms
9y - 9 = 180
9y = 189 divide both sides by 9
y = 21

At a high school football game, admission is $5 for students and $10 for non-students. There were 500 people at the first game, and the school made $4,000 from admissions. In this activity, you will find the number of students and non-students at the game.
Please write the two equations algebraically and then solve :)
Answer:x = 200 students
y = 300 non-students
Step-by-step explanation:
5x + 10y = 4000
x + y = 500
Set y = 500-x
5x + 10(500-x) = 4000
5x + 5000-10x
-5x + 5000 = 4000
-5x = -1000
x = 200 students
y = 300 non-students
Let's double checks
5(200) + 10(300)
1000 + 3000 = 4000
−3(x + 3) = −3(x + 1) − 5
Answer:
No real solutions
Step-by-step explanation:
Distribute the -3
-3x - 9 = -3x -3 -5
-3x - 9 = -3x - 8
add 3x to both sides
-9 = -8

match each equation with its solution.
A) -1.4 n + 2.1 = 6.58
a) n = -32
B) 4 n - 2 3/4 = -22 3/4
b) n = -5
C) 5.7 n + 4.1 = 2.96
c) n = -0.2
D) n/8 + 1/2 = -3 1/2
d) n = -3.2
Thank you..
Answer:
(A) and c
(B) and a
(C) and d
(D) and b
Step-by-step explanation:
these are from the calculations i got, what you do is minus the two answers you have to find n
For equations,
A) -1.4 n + 2.1 = 6.58 then n = 3.2
B) 4 n - 2 3/4 = -22 3/4 then n=24
C) 5.7 n + 4.1 = 2.96 then n=-0.2
D) n/8 + 1/2 = -3 1/2 then n=24
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A) -1.4 n + 2.1 = 6.58
Subtract 2.1 on both sides
1.4n=6.58-2.1
1.4n=4.48
Divide both sides by 1.4
n=3.2
B) 4 n - 2 3/4 = -22 3/4
4n-11/4=-85/4
4n=85/4+11/4
4n=96
Divide both sides by 4
n=24
C) 5.7 n + 4.1 = 2.96
5.7 n = 2.96- 4.1
5.7n=-1.14
n=-0.2
D) n/8 + 1/2 = -3 1/2
n/8 = -3 1/2-1/2
n/8 = -5/2-1/2
n/8 = -3
n=-24
Hence, equations A) -1.4 n + 2.1 = 6.58 then n = 3.2
B) 4 n - 2 3/4 = -22 3/4 then n=24
C) 5.7 n + 4.1 = 2.96 then n=-0.2
D) n/8 + 1/2 = -3 1/2 then n=24

What is the mean?
Answer:
The mean is 15.25.
Step-by-step explanation:
First, we need to be sure we know that the mean is the average number in the group of numbers. That doesn't mean the most repeated or the number in the middle. Simply, the average.
To find the mean of a group of numbers you simply add them all together and divide by the number of numbers. So, let's solve.
12 + 14 + 17 + 18
= 61 ÷ 4
= 15.25
So the mean of 12, 14, 17, and 18 is 15.25.
