If you ask Megan how many dogs she has, she answers with a riddle: "Four-sevenths of my dogs plus 9." How many dogs does she have?
Step-by-step explanation:
This is a simple system of equations problem, with our equation being:
[tex]\frac{4}{7}x+9=x[/tex]
We know this as her dogs (x) is equal to 4/7 of her dogs (x) plus 9. Now all we must do is solve for x:
[tex]\frac{4}{7}x+9=x\\\\\frac{4}{7}x=x-9\\\\\frac{4}{7}x=\frac{7}{7}x-9\\\\\frac{-3}{7}x=-9\\\\x=21[/tex]

In the morning, there were 260 cars in a parking lot. In the evening, the number of cars decreased by 35%. How many cars remained in the parking lot?
169 cars are remaining in the parking lot
How to calculate the number of cars left in the parking lot ?There are 260 cars in the parking lot
This number decreased by 35%
100% - 35%
= 65%
65/100
= 0.65
The number of cars left can be calculated as follows
= 260 × 0.65
= 169
Hence there are 169 cars left in the parking lot

What are Parallel and perpendicular lines in terms of slope of lines?Two lines are said to be parallel if : m(1) = m(2).
Two lines are perpendicular to each other if : m(1) x m(2) = -1.
We have to classify the set of these lines as; Parallel, Perpendicular or Cannot Be Determined.
1. Lines AB and CD are both perpendicular to the line EF, then AB |is parallel to CD.
2. The lines CD and GH cannot be defined, because the diagram doesn't contain any information about angles at which these lines intersect.
3. The lines AB and GH cannot be defined, because the diagram doesn't contain any information about angles at which these lines intersect.

Answer: The number 0.1453 belong to rational numbers and real numbers.
Step-by-step explanation:
The whole numbers are 0,1,2,3,..., so 0.1453¯¯¯¯¯ (repeat bar on 53)does not belong to the set of whole numbers. The integers are the whole numbers and their opposites, so 0.1453¯¯¯¯¯(repeat bar on 53) does not belong to the set of integers. Rational numbers include decimals that repeat or stop.The integers are the whole numbers and their opposites, so 0.1453¯¯¯¯¯(repeat bar on 53) does not belong to the set of integers.Rational numbers include decimals that repeat or stop.

if x/x+3 = 0.625, what is
the value of x-4/x-1
Solving the first equation we can find that the value of x is x = 5, then we can replace that in the other expression and we can see that the value of the expression is 1/4.
What is the value of x-4/x-1?First, we need to find the value of x.
We know that:
x/(x + 3) = 0.625
Solving that equation we will get:
x = 0.625*(x + 3)
x - 0.625*x = 3*0.625
x*(1 - 0.625) = 3*0.625
x = 3*0.625/(1 - 0.625) = 5
So the value of x is 5 (and it will be in both expressions)
Now we can replace that value in the given expression (just replace the variable x by the number 5)
(x - 4)/(x - 1) = (5 - 4)/(5 - 1) = 1/4
The value of the expression is 1/4.

Does Ling have enough fabric for her craft activity?
We know that she is in charge of 40 campers, and she wants to make fabric-covered frames, such that each one needs 1/6 yards of fabric.
We know that he has a total of 6 + 2/3 yards to do this, and we need to see if that is enough.
Now, for each one of the 40 campers she needs 1/6 yards, so the total amount she needs is given by the product:
T = 40*(1/6 yards) = 40/6 yards = (36 + 4)/6 yards = (6 + 4/6) yards
T = (6 + 2/3) yards
So she has the exact amount of fabric that she needs for this project.

In the expression 5 + 2 + 5x + 2x + x we can combine the like terms to get the simplified form of the expression as 7 +8x.
What are like terms?If two words have the same variable portion, we refer to them as "like terms." When comparing algebraic terms to locate similar terms, we first disregard the coefficients and merely check to see if the variables and exponents are the same. The terms that meet this requirement are known as like terms.
Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

What is a translation?
The process of changing the location of the image on the coordinate system will be known as the translation.
Our point A(x,y) becomes A' when a point is rotated 90 degrees counterclockwise about the origin (-y,x). To put it another way, flip x and y, and make y-negative.
Given that point, G is translated to 90 degrees. The translated coordinates of point G will be calculated as:-

Drake Kennedy's regular-time pay rate is $12.73 an hour. Last week he was paid for 37.5 hours at his
regular rate and for 5 hours at a time-and-a-half overtime rate. Find Drake's gross pay for week?
Answer:First, determine the total number of hours worked by multiplying the hours per week by the number of weeks in a year (52). Next, divide this number from the annual salary.if an employee has a salary of $50,000 and works 40 hours per week, the hourly rate is $50,000/2,080 (40 x 52) = $24.04.
Step-by-step explanation:
Divide the gross pay by the wage hours worked. For example, if your records show that the employee was paid $4,000 for the total month, divide 4,000 by 172 to reach $23.26. This is an accurate representation of an hourly rate for that employee's monthly work.
