You and a friend are in school and are trying to figure out where to eat. You told her that you would like to go to your favorite pizza place that is 5 miles away from your home. Both of you know that your home is 10 miles away from school. Approximately how far is the pizza place from the school?The pizza place is between approximately 5 to 15 miles away from school.Not enough information to solve the problem.The pizza place is approximately less than 5 miles away from school.
Okay, here we have this:
Considering the provided information, we are going to identify approximately how far is the pizza place from the school, so we obtain the following:
Then from the given information we can identify that the pizzeria can be 5 miles in the same direction from the school or 5 miles in any other direction,
This means that in the best case the distance from the pizzeria to the school is 5 miles (if it is halfway), and in the worst case it is 15 miles (if it is in a completely opposite sense).
And in an average case it can be at an angle other than 180 degrees, with which the distance would be between 5 and 15 miles, therefore the correct answer is:
The pizza place is between approximately 5 to 15 miles away from school.

slope of line is -3 for points (1,0) and (0,3)
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
From graph let us take two points (1, 0) and (0, 3)
x₁=1, x₂=0, y₁=0,y₂=3
Substitute these values in slope formula
m=3-0/0-1
m=3/-1

In triangle ABC, if AC = 17 cm, CB = 10 cm, AD = x cm, DB = y cm and AB = 21 cm, find the value of (x − y).
The value of (x-y) is 9 cm for the given triangle ABC.
According to the question,
We have the following information:
In triangle ABC, if AC = 17 cm, CB = 10 cm, AD = x cm, DB = y cm and AB = 21 cm.
So, we have:
x+y = 21 cm
y = (21-x) cm
Using Pythagoras theorem in right-angled triangle ADC and CDB:
[tex]AC^{2} = AD^{2} +CD^{2}[/tex] and [tex]BC^{2} = BD^{2}+CD^{2}[/tex]
Now, we have the equal values of [tex]CD^{2}[/tex]:
[tex]17^{2} -x^{2} = 10^{2} -y^{2}[/tex]
289 -[tex]x^{2}[/tex] = 100 - [tex](21-x)^{2}[/tex]
289 - [tex]x^{2}[/tex] = 100 - (441+[tex]x^{2}[/tex]-42x)
289-[tex]x^{2}[/tex] = 100 - 441-[tex]x^{2}[/tex] + 42x
289 = 100 -441+42x
42x-331 = 289
42x = 289+331
42x = 630
x = 630/42
x = 15 cm
y = 21-x
y = 21-15
y = 6 cm
Now, x-y = 15-6
x-y = 9 cm
Hence, the value of (x-y) is 9 cm.

jamals lawn is shaped like a square with an area of 224.9ft2 .which measurement is closest to the side length of his lawn in feet
We use the formula for the area "A" of a square with equal sides of length "l":
[tex]A=l^2[/tex]Since we know the value of the area is:
[tex]A=224.9ft^2[/tex]We substitute that value into the formula for the area:
[tex]224.9ft^2=l^2[/tex]Next, we take the square root of both sides of the equation:
[tex]\sqrt[]{224.9ft^2}=\sqrt[]{l^2}[/tex]On the right side, the exponent and the square root will cancel, and we will get "l", and on the left side, we calculate the square root:

Dan's dog walking job pays $15 per hour his job as a car wash attendant pays $400 each week Dan wants to know how many hours he needs to spend walking dogs to earn more than $520 in a week. Which three equalities can model this situation? select all the correct answers.
Answer:
520<400+15x
15x>120
15x+400>520
Explanation:
Pay of Dan's car wash attendant job =$400 per week
The amount he earns per hour walking dogs = $15
Let the number of hours spent walking dogs in a week = x
Therefore, total earning for walking dogs =$15x
Since he wants to earn more than $520, we have that:
[tex]15x+400>520\text{ (Option F)}[/tex]We can rewrite this as:
[tex]520<400+15x\text{ (Option B)}[/tex]If we collect like terms, we have:
[tex]\begin{gathered} 520-400<15x \\ 120<15x \\ \implies15x>120\text{ (Option C)} \end{gathered}[/tex]So the inequalities are:

Hence, B is the answer.2. If 25% of 80 is 10% of a number? What is number?
Given that 25% of 80 is 10% of a number.
We have to find the number.
Let the number be x. So, 25% of 80 is equal to 10% of x. Therefore,
[tex]\begin{gathered} \frac{10}{100}\times x=\frac{25}{100}\times80 \\ 10x=2000 \\ x=\frac{2000}{10} \\ x=200 \end{gathered}[/tex]Thus, the number is 200.

Step-by-step explanation:
as the intersection angles of parallel lines with a third line are the same for both parallel lines (and then vice versa for the other pair of parallel lines), we have a lot of equal angles here.
not to forget : the sum of all angles around a single point on one side of a line is always 180°.
51 = (y + z)
(6z + 9y) = x
x + (x + z) = x + 51 = 180°
x = 129°
we have now
y + z = 51
9y + 6z = 129
so,
z = 51 - y
9y + 6(51 - y) = 129
9y + 306 - 6y = 129
3y = -177
y = -59
z = 51 - y = 51 - -59 = 51 + 59 = 110
the value of z that makes j and k parallel is 110.

What is linear equation?
An algebraic equation with simply a constant and a first-order (linear) term, such as y=mx+b, where m is the slope and b is the y-intercept, is known as a linear equation.
Let east high school have x students
West high school have 2x - 250
Total count of students from both the schools are 2858 students.
Then we get
x + 2x-250 = 2858
=> 3x - 250 = 2858
=> 3x = 2858 + 250
=> 3x = 3108
