Answer:
8 = 16
Step-by-step explanation:
1/4 = 4 /8
Cross multiply:
1 * 8 = 4 * 4
Simplifying
1 * 8 = 4 * 4
Multiply 1 * 8
8 = 4 * 4
Multiply 4 * 4
8 = 16
Solving
8 = 16
0.4
40%
4%
2/5
Answer:
All but 4%
Step-by-step explanation:
2/5-1/4
8/20 - 5/20
(8-5)/20
= 3/20

The triangle inequality theorem is an important part of geometry in order to mention the dimension of the sides of a triangle clearly.
The triangle inequality theorem states that, the sum of the length of two sides must be greater than the length of the third side of that triangle.
Here, three sides of this triangle ABC are AB, BC, and CA.
Therefore, as per the triangle inequality theorem:
(Length of AB + length of BC) must be greater than the length of CA.
Therefore, (AB + BC) > CA.
(Length of BC + length of CA) must be greater than the length of AB.
Therefore, (BC + CA) > AB.
(Length of AB + length of CA) must be greater than the length of BC.
Therefore, (AB + CA) > BC
For an example, if we are running in a triangular shaped track, then it can be easily understandable.
Now, if we start running from the point A, then to reach the point B the shortest path will be the straight line AB.
Instead of that, if we go to the C point at first and then reach the point B, then we will travel more distance.
Similarly, starting from the other points, we will get the same results.

The area of the circle on the paper is 4.5 cm when traced around the edge of the quarter on a sheet of paper.
The area of the circle is equal to the product of the square of the radius of the circle and pi.
A = πr²
where 'r' is the radius of the circle
The diameter of a quarter is 2.4 cm. You trace around the edge of the quarter on a sheet of paper.
The area of the circle on the paper = πr²
Here r = (diameter of a quarter)/2 = 2.4/2 = 1.2 cm
The area of the circle on the paper = π(1.2)²
The area of the circle on the paper = π × 1.44
The area of the circle on the paper = 4.5238
Round the answer to the nearest tenth.
The area of the circle on the paper = 4.5 cm
Thus, the area of the circle on the paper is 4.5 cm

Answer:its 4.5
Step-by-step explanation:
-x + (−3) = x + 3
Step-by-step explanation:
-x - 3 = x + 3
Solving like terms
-3 - 3 = x + x
-6 = 2x
-6 / 2 = x
-3 = x
Answer:
-3
Step-by-step explanation:
You are trying to solve for x in this situation. So the first thing you want to do is choose a side (it doesn't matter in this situation bc there is an x on either side of the =) and isolate the x.
**I'm going to choose the left side cause why not** Add the -3 to both sides to get -x by itself:
-x + (−3) = x + 3
-x -3= x+3
* quick side note, when you add a negative number to a positive, it has the same effect as subtracting
-x=x+6
Now -x is by itself but there is still another x, so combine like terms again:
-2x=6
Now simplify by dividing -2 to both sides:
x=-3
