=========================================================
Explanation:
Let's say we have a triangle with sides x,y,z
Also, let's further say we know that x = 19 and y = 28 (from AB and BC respectively).
The third missing side z can't be nailed down to a single number, but we can establish a possible range. That range is
y-x < z < y+x
28-19 < z < 28+19
9 < z < 47
So any number between 9 and 47, excluding both endpoints, will work as a possible side length for the third missing side.
Something like 7 inches is too small, so we rule out choice B. Choice D is ruled out since 49 inches is too big. Same goes for choice A also.
The only thing left is choice C. The 42 is between 9 and 47
In other words, 9 < 42 < 47 is true.
So that's why the third missing side could be 42 inches.
Side note: I'm using a modification of the triangle inequality theorem.
A furniture store is having a sale on couches that cost $1000 or more. A 10% discount will be applied. If a couch that has an original cost of $2000 is purchased, what will the final cost be after the 10% discount is applied?
Answer:
200$
Step-by-step explanation:
2000 is more than 100p so the discount is 10% right so
2000 over 1 multiple by 1 over 10 equals to 200$
im confused on this question
Answer: the system has no solution because 2x -1 does not wok because e1 dose not have an x at the end
Step-by-step explanation:
What If? A right triangle area Of 18 square inches.
a. If the triangle is an isosceles triangle, What the lengths
of the legs of the triangle?
b. If the triangle is not an triangle, what the possible
lengths of the Legs, if the lengths are numbers?
Answer:
The answer to A is 6 The answer to B is more complicated
Step-by-step explanation:
B : area = 18
36 =2x18
36= 3x12
36=4x9
The triangle can have dimensions in the form of bxh in 36 =2x18 or 36= 3x12 or 36=4x9

Please anwer the question
Answer:
$520.96
Step-by-step explanation:
This is a compound shape made of 1 rectangle and two semi circles which makes 1 full circle.
Area of Rectangle = L x W
Area of circle is =pi x radius squared
Area of Rectangle is 5ft x 4ft = 20 ft squared.
Area of circle is = 12.56 ft squared
- Diameter of the circle is 4ft, radius is 1/2 diameter
- Radius is 2ft, 2 x 2 = 4ft
(pi) 3.14 x 4ft = 12.56 ft squared.
As it is a compound shape you need to add
Area of Square + Area of circle =
20 ft squared + 12.56 ft squared =
Total Area of window is 32.56 ft squared
$16 = 1 square foot
$16 × 32.56 = $520.96

how many solutions does the system of equations have?
A) No solution
B) One solution: x = 0, y = 0
C) One solution: x = 1, y = 5
D) Infinite many solutions
Answer:
no solution
Step-by-step explanation:
a solution would mean a point where the two lines cross. theres no such thing for parallel lines.
but if the lines are the same, they are parallel and cross everywhere, that would give infinite solutions.
if they would cross once, it would mean one solution

Write an algebraic expression to represent the following phrase:
the sum of a number and 0.5
no links
Answer:
x + 0.5
Step-by-step explanation:
The sum of implies that addition is involved.
Since the number is unknown, you use a variable. For example, x.
You're adding x and 0.5 so you would use a plus sign.
The algebraic expression would be x + 0.5.
Hope that helps.

Answer:
Hi, there I'll help you since no one helped you which I felt sad lol, but anyway here's your answer
x=2,y=7→ y=11-2x;4x-3y=-13
x=5,y=2→ 2x+y=12;x=9−2y
x=3,y=5→ y=10+x;-3x+3y=30
x=7,y=3→ x+3y=16;2x−y=11
Hope this helps :)

Taking SOL's need help!!!!
Answer:
The surface area is 86.9
Step-by-step explanation:
First find the area of the base:
5.3 • 2 = 10.6
The area opposite of the base are equal:
10.6 + 10.6 = 21.2
Find the area of the front rectangle:
5.3 • 4.5 = 23.85
The area opposite of the rectangle are equal:
23.85 + 23.85 = 47.7
Find the area of the rectangle on the sides:
4.5 • 2 = 9
The area opposite of the shape on the side are equal:
9 + 9 = 18
Add up the areas:
21.2 + 47.7 + 18 = 86.9
Which equation is true for x = 1.8?
x/3 = 0.6
3/x = 7.2
x + 3.1 = 5.5
6 = 3.6 + x
Answer:
x / 3 = 0.6 is the true equation
Step-by-step explanation:
x / 3 = 0.6
x = 0.6 * 3
x = 9/5 or x = 1.8
hope this helps.....
Which expression is equivalent to 7a - 8 - 12a + 4?
I need step by step
Answer: First of all, add up the expressions with the same variables and the numbers.
7a-8-12a+4
=7a-12a-8+4
=-5a-4
or
=-(5a+4)
Both of them can be counted ans equivalent expression since all three of them works the same. Only the expression(way of writing) seems different.
Answer:
_ 5a - 4
Step-by-step explanation:
Combine Like Terms:
=7a + − 8 + −12a + 4
=( 7a + −12a ) + (− 8 + 4 )
=− 5a - 4 Answer!
