We are given the steps that are laid to determine the value of x in the expression |2x -4| - 3 = 3. First step is to add 3 to both sides, then simplify, then determine x. The first incorrect step is step 1 since we add not subtract.

Order the fractions from least to greatest

My name is Ann [436]

Answer:

1/4, 2/5, 1/2, 3/5, 2/3, 13/18, 7/9, 5/6, 2 6/15, 2 4/9, 2 3/5, 2 2/3, 6 3/8, 6 1/2,

6 3/4, 6 5/6

Step-by-step explanation:

I like to organize decimals more than fractions because it's easier for me, so I'm changing each of them to a decimal. You don't have to do this though.

To change a fraction to a decimal, if it is simplified, make it an improper fraction
Then, divide the numerator from the denominator. For example, 1/4 = 0.25 because 1 divided by 4 = 0.25

3/5 = 0.60,
1/4 = 0.25,
1/2 = 0.50,
2/5 = 0.40,
7/9 = 0.7 repeating or just 0.78 rounded,
13/18 = 0.72 repeating or 0.73 rounded,
5/6 = 0.83 repeating or 0.84 rounded,
2/3 = 0.66 repeating or 0.67 simplified,
6 3/4 = 27/4 or 6.75,
6 1/2 = 13/2 = 6.50,
6 5/6 = 41/6 = 6.83 repeating or 6.84
6 3/8 = 51/8 = 6.375 or 6.38
2 2/3 = 8/3 = 2.66 repeating or 2.67
2 6/15 = 36/15 = 2.40
2 3/5 = 13/5 = 2.60
2 4/9 = 22/9 = 2.44 repeating or 2.45

Ordering them is pretty easy, just start from the smallest and move to the greatest!

0.25 = 1/4
0.40 = 2/5
0.50 = 1/2
0.60 = 3/5
0.67 = 2/3
0.73 = 13/18
0.78 = 7/9
0.84 = 5/6
2.40 = 2 6/15
2.45 = 2 4/9
2.60 = 2 3/5
2.67 = 2 2/3
6.38 = 6 3/8
6.50 = 6 1/2
6.75 = 6 3/4
6.84 = 6 5/6

An isosceles trapezoid is a quadrilateral with two congruent legs, a pair of parallel bases, and congruent base angles. Prove th

seraphim [82]

Answer:

The answer is below

Step-by-step explanation:

We must first define the concepts a little:

We have that when the sides are congruent that is to say that they have the same direction and the same size and also the two opposite sides are parallel, the angles will be the same.

Now, in an isosceles triangle, two angles are congruent, because their two sides are congruent.

An equilateral triangle with side length 6 and an equilateral triangle with side length 15 determine whether the polygons are si

tino4ka555 [31]

An equilateral triangle with side length 6 is similar to an equilateral triangle with side length 15

Solution:

Given that we have to find whether the polygons are similar

An equilateral triangle with side length 6

An equilateral triangle is a triangle in which all three sides are equal

All three internal angles are also congruent to each other and are each 60°

Let ABC be a equilateral triangle with side length 6

Since all three sides are equal,

AB = 6

BC = 6

CA = 6

Also, angle A = 60 degrees and angle B = 60 degrees and angle C = 60 degrees

An equilateral triangle with side length 15

Let XYZ be a equilateral triangle with side length 15

Since all three sides are equal in equilateral triangle,

XY = 15

YZ = 15

ZX = 15

Also, angle X = 60 degrees and angle Y = 60 degrees and angle Z = 60 degrees

Two triangles are similar if they have the same angles and the side lengths are proportional.

Since,

$\frac{AB}{XY} = \frac{BC}{YZ} = \frac{CA}{ZX} = \frac{6}{15} = \frac{2}{5}$

Also,

Angle A = angle X = 60 degrees

Angle B = angle Y = 60 degrees

Angle C = angle Z = 60 degrees

Since equilateral triangles all have the same angles, and all side lengths are equal, any two equilateral triangles must be similar.
