Jordyn and Anya left a 30% tip after having lunch at a restaurant. The amount of the tip was $14.10. Jordyn's lunch cost $22. Write and solve an equation you can use to find x, the cost of Anya's lunch.
The cost of Anya's lunch would be = $25
What is lunch?Lunch is the type of meal that is taken after the noon day or in the afternoon.
The percentage of tip left by Jordyn and Anya = 30%
The amount of the tip = $14.10
If 30% = 14.10
100% = $x
$x = 100 × 14.10/30
$x = 1,410/30
$x = 1,410/30
$x = $47
This is the total amount for the cost of lunch.
To find Anya's cost for lunch would be;
Total cost - Jordyn lunch cost = Anya lunch cost
Anya lunch cost = 47 - 22
= $25

Select the transformations of g(x) = |1-2x+6| in relation to the parent function. HURRY PLEASE!!!
Answer:
Translated right [tex]\frac{7}{2}[/tex] units and vertical stretch
OR
translated right 3.5 units and vertical stretch
bcz
[tex]\frac{7}{2} =3.5[/tex]
Step-by-step explanation:
The absolute function is given as:
[tex]g(x) = |1-2x+6|[/tex]
If we simplify the equation, then we have
[tex]g(x) = |1-2x+6|\\g(x)=|-2x+6+1|\\g(x)=|-2x+7|\\g(x)=2|x-\frac{7}{2} |[/tex]
Now we can say that the transformation of g(x) to the parent function will be translated right [tex]\frac{7}{2}[/tex] units and vertical stretch (bcz you have a number (2) multiplying the function).
If the sign of the number that adds to the independent variable is negative, the transformation will be translated to the right, and if it is positive, it will be translated to the left.
154= -4(8+6r)+24r I want to know the answer
The equation 154 = -4(8+6r) + 24r has no solution because the variable becomes 0.
How to solve equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
We have to find the variable r of the equation to solve the equation.
A variable is a number represented with letters in an equation.
Therefore, let's find the variable r in the equation.
154 = -4(8+6r) + 24r
open the brackets on the right side of the equation
154 = - 32 - 24r + 24r
154 = -32 + 0

Autumn has 55 cups of yogurt to make smoothies. Each smoothie uses 1/3
cup of yogurt. How many smoothies can Autumn make with the yogurt?
The total number of smoothies that Autumn can make with the yoghurt is 165.
We know that the total number of cups of yoghurt that Autumn needs to make smoothies is 55. Each smoothie uses 1/3 cup of yogurt. We need to calculate the total number of smoothies that Autumn can make with the yogurt.
Let the total number of smoothies be represented by the variable "N''. We will use the unitary method. The total number of smoothies that can be made is the ratio of the total number of cups of yoghurt to the fraction of a cup used to make one smoothie.
N = 55/(1/3)
N = 55*3
N = 165
Hence, Autumn can make 165 smoothies from 55 cups of yogurt.

O (3, 4)

Answer:
(3, -4)
Step-by-step explanation:
To solve the system of equations by substitution, start by labelling the 2 given information.
y = x - 7 -----(1)
5x + 2y = 7 -----(2)
Substitute (1) into (2):
5x + 2(x - 7) = 7
Expand:
5x + 2x - 14= 7
7x = 14 + 7
7x = 21
Divide both sides by 7:
x = 21 ÷ 7
x = 3
Substitute into (1):
y = 3 - 7
y = -4

Harold filled his swimming pool over the weekend. The pool has a capacity of 540 gallons. Harold put in 180 gallons of water on Saturday. The garden hose that Harold used supplies 9 gallons of water per minute. How long did it take for Harold to fill the pool to capacity on Sunday? Define a variable for the unknown quantity. Write and solve an equation to answer the question.
Pool Capacity = 540 gallons
Saturday = 180 gallons
Hose water rate = 9 gallons per minute
540 = 180+9m
Where m is the number of minutes (independent variable)
Solve for m :
540-180 = 9m
360 = 9m
360/9= m
40 =m
It will take 40 minutes.
Match the pair of points with the slope of the line that joins them. (4,7) and (6,2)

The general equation of the line is ;
[tex]y=m\cdot x+b[/tex]where m is the slope and b is y - intercept
the slope = Rise/Run
Rise = 7 - 2 = 5
Run = 4 - 6 = -2
so, the slope :
[tex]m=\frac{5}{-2}=-2.5[/tex]So, the equation of the line :
[tex]y=-\text{2}.5x+b[/tex]Using any point from the given points to find the value of b
So, using ( 4 , 7 )
when x = 4 , y = 7

To answer this question, we need to take into account that the two ships continue sailing at the same rate and direction, and we can solve this using the unit rate concept, as follows:
[tex]\frac{3.2}{2.5}\frac{miles}{h}=1.28\frac{miles}{h}[/tex]If they continue sailing at this same rate, then, after two hours they will be:
