Which group of ordered pairs are on the line given by the equation 5x−2y=6?
Answer:
(0, -3), (2, 2), (4,7) these are just some points
Step-by-step explanation:
Put the equation in y=mx+b format. It will be 2y=5x-6.
y=5/2x -3
the first point will be (0, -3) because of the y-intercept which is negative 3. You can graph the slope from that point to get (2, 2) and (4, 7). You can get more points too
Answer:
There are infinite ordered pairs are on the line because it has infinite solutions.
Step-by-step explanation:
5x - 2y = 6
-5x -5x
-2y = -5x + 6
-2y/2 = -5x/-2 + 6/-2
y = 5/2x - 3
5x - 2(5/2x - 3) = 6
5x - 5x + 6 = 6
6 = 6
It takes Austin 8 hours longer than Elliott to construct a wooden chair in shop class. When the classmates work together, they can complete one chair in 3 hours. This situation can be represented by this expression, where t is the amount of time, in hours, it takes Elliott to complete a chair on his own.
The equivalent expression obtained using the least common multiple concept is [tex] \frac{6t + 24}{t^{2} +8}[/tex]
To solve, we need to obtain the L. C. M of the denominator values :
The L. C. M of t and t + 8 = [tex] t^{2} + 8t[/tex]
Hence,
[tex]\frac{3}{t} + \frac{3}{t+8} = \frac{6t + 24}{t^{2} +8}[/tex]
Therefore, the equivalent expression which represents the situation described above ls ;[tex] \frac{6t + 24}{t^{2} + 8t}[/tex]

many full laps can be complete in 1 hour?
Answer:
1 min 56 seconds
Step-by-step explanation:
The number of laps covered in 1 hour will be 31.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Garrett can complete four laps around the track in 7 minutes and 45 seconds.
The number of laps covered in 1 hour will be;-
7 min 45 sec = 4 laps
7³/₄ min = 4 laps
1 min = 4 / 7³/₄ laps
60 min = 1 hour = ( 4 x 60 ) / ( 31 / 4 )
60 min = ( 4 x 4 x 60 ) / 31
60 min = 31 laps
Hence, the number of laps will be 31.

Answer:
y = mx + b
Step-by-step explanation:
Substitute in the slope intercept formula
m = slope
x = first number in the point
y = second number in the point
and solve for b
Question 1
m=-1/2, x= -4 y=-2 substitute
-4 = -1/2(-4) + b
-4 = 2 + b
-4 -2 = 2 -2 + b

the answer is the same
The value of x is (2w - t)/5.
The value of w is (5x + t)/2.
The value of t is 2w - 5x.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
5x - 2w + t = 0
Solve for x.
5x - 2w + t = 0
5x = 2w - t
x = (2w - t)/5
Solve for w.
5x - 2w + t = 0
5x + t = 2w
w = (5x + t)/2
Solve for t.
5x - 2w + t = 0
t = 2w - 5x
Thus,
The value of x, w, and t is given above.

A recipe calls for 3 cups of orange juice for every 4 cups of fruit punch. If a person makes a large batch of this recipe, how many cups of fruit punch will be needed if 12 cups of orange juice are used? Create a ratio table to solve.
The number of cups of fruit punch will be equal to 16.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that a recipe calls for 3 cups of orange juice for every 4 cups of fruit punch. For 12 cups of orange juice.
Since now the cups of orange juice ratio has been altered, the cups of fruit punch ratio needs to be equally altered as well.
(3 / 4) = ( 12 / x)
x = 48 / 3
x = 16
Now that they are equally altered, the new ratio would be 12:16.
Therefore, the number of cups of fruit punch will be equal to 16.

Tina has two rectangular playpens to keep her new pet dogs. The first rectangle has a width of 6 feet and a length of x - 4 feet. The second rectangle has a width of 8 feet and a length of x + 2 feet. What is the sum of the two perimeters?
Answer:
4x+24 ft.
Step-by-step explanation:
Perimeter of first rectangular playpen mentioned: 2(6+x-4), which can be simplified to 2(x+2) = 2x + 4.
Perimeter of second playpen mentioned: 2(8+x+2), which can be simplified to 2(x+10) = 2x+20.
Add these two together: 2x+4 + 2x+20 = 4x+24. Don't forget to add units: 4x+24 ft.

Answer:
A. 3
B. 4.5
Explanation:
A. 2(5x - 3) = 24
10x - 6 = 24
then add six on both sides
U get 10x = 30
divide 10 on both sides
U get x is 3
B. 5(2x + 1) = 50
10x + 5 = 50
minus five on both sides
10x = 45
divide by 10 on both sides
The answer is x = 4.5
