First you find 2% of 3000 which is 60
Next you find 2% of 3060 =61.2
next 2% of 3120 =62.4
last 2% of 3180 is 63.6

does anyone know how to do this by solving with substitution
Answers
Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3

A store manager wants to determine how much to pay her employees. The number of hours the employees work is x, and the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation 10y-30x=20 . The business owner states that the employees should be paid a wage given by the equation 6y+30x=60. If the two equations were added then simplified to determine hourly wage, y, how much would the employees be paid?
Answers
Answer:
The employees will work for 1 hour, will earn $5 per hour and will be paid $5
Step-by-step explanation:
System of Equations
The number of hours the employees work is x.
And the hourly wage that they are paid is y. The store manager is willing to pay the employees a wage given by the equation
10y-30x=20
The business owner states that the employees should be paid a wage given by the equation
6y+30x=60
Adding both equations we have:
16y = 80
Dividing by 16:
y = 80/16 = 5
Substituting into the first equation:
10*5-30x=20
Operating and simplifying:
50-30x=20
50 - 20 = 30x
30x = 30
x = 30/30 = 1
Thus, the employees will work for 1 hour, will earn $5 per hour and will be paid $5
Beyonce is solving a system of equations: 2x – 3y = -2
4x + y = 24
She decides to use the elimination method to find the solution. She multiplies the second equation by 3 and adds it to the first equation to find 14x = 70, showing her that x = 5. Beyonce finds that y = 4.
Step 3: 4x + y = 24
4(5) + y = 24
20 + y = 24
-20 -20
y = 4
Step 1: 3(4x + y = 24) → 12x + 3y = 72
Step 2: 2x – 3y = -2
Solution: (5, 4)
+ 12x + 3y = 72
14x = 70
→ x = 5
Thinking about this process, Beyonce says out loud, “There are lots of ways I could go about solving this problem. I could do the method above or I could multiply the first equation by -2 and add the second.
Step 3: 4x + y = 24
4x + 4 = 24
-4 -4
4x = 20
x = 5
Step 1: -2(2x – 3y = -2) → -4x + 6y = 4
Solution: (5, 4)
Step 2: -4x + 6y = 4
+ 4x + y = 24
7y= 28
→ y = 4
“I seem to find that there is only one solution to the two equations, but I wonder if I will get the same solution if I use a different method?”
Explain how you know that a system of equations has no solution.
Answers
Answer:
Step-by-step explanation:
A system of equations has no solutions if you end up with a contradiction. For example, the system of two equations
y = 2x + 4
y = 2x
If you subtract the second equation from the first, you get
0 = 4
an obvious contradiction. If you were to graph the equations, you would see that the lines are parallel. They never intersect, so there is no point that satisfies both equations.

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $1.50. Today they made $135.50 from the 117 wraps sold. How many of the wraps sold were vegetarian?
Answers
Answer:
Number of vegetarian wraps = 80
Number of chicken wraps = 37
Step-by-step explanation:
Let
Number of vegetarian wraps = x
Number of chicken wraps = y
x + y = 117 (1)
x + 1.5y = 135.50 (2)
Subtract (1) from (2) to eliminate x
1.50y - y = 135.50 - 117
0.50y = 18.50
y = 18.50/0.50
y = 37
Substitute y = 37 into (1)
x + y = 117 (1)
x + 37 = 117
x = 117 - 37
x = 80
Number of vegetarian wraps = 80
Number of chicken wraps = 37

A hiking trail rises 6 feet for every horizontal change of 100 feet. What is the slope of the hiking trail?
Answers
Given:
A hiking trail rises 6 feet for every horizontal change of 100 feet.
To find:
The slope of the hiking trail.
Solution:
We have,
Rise = 6 ft
Run = 100 ft
We know that
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{6}{100}[/tex]
[tex]Slope=0.06[/tex]
Therefore, the slope of the hiking trail is 0.06.
The slope of the hiking trail is equal to 0.06.
Given the following data:
Vertical distance (rise) = 6 feetHorizontal distance (running) = 100 feetTo find the slope of the hiking trail, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Mathematically, the slope of a hiking trail is given by the formula:
[tex]Slope = \frac{Rise}{Running}[/tex]
Where:
V is the rising vertical distance of an object.H is the horizontal distance an object runs through.Substituting the given parameters into the formula, we have;
[tex]Slope = \frac{6}{100}[/tex]
Slope = 0.06
