First, change both mixed numbers to improper fractions

4 1/5 = 21/5
1 4/5 = 9/5

because they already have a common denominator, just subtract them

21/5 - 9/5 = 12/5

Triangles ABC and DEF are similar triangles. What are the lengths of the unknown sides?
Aleksandr-060686 [28]

Answer:

D)

DF = 52

AB = 48

Step-by-step explanation:

Use the two lengths of sides already given.

Divide to find the scale factor:

20 / 5 = 4

Scale factor: 4

Now multiply to find the unknown sides:

13 × 4  = 52

12 × 4 = 48

DF = 52

AB = 48

Hope this helped.

The perimeter of a rectangle is 52. The length is 2 more than 2 times the width. Find the width and length.
Arlecino [84]
Formula for the perimeter of a rectangle = 2(L + W).
let the width be x
length = 2 + 2x
substitute respectively
52 = 2(2 + 2x + x)
52 = 2 (2 + 3x)
52 = 4 + 6x
52 - 4 = 6x
48 = 6x
divide both sides by 6
48/6 = 6x/6
8 = x
width = 8
length = 2 + 2x = 2 + 2(8) = 2 + 16 = 18

110- (5x) 70, 110- What is the value of x? 14 15 16 17​
Grace [21]

The value of x is 14 because the sum of all angles in kite is 360 degree option first 14 is correct.

<h3>What is linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The question is in the picture please refer to the attached picture.

We know the sum of all angles in a kite is 360 degree

110 + (5x) + 110 + 70 = 360

290 + 5x = 360

5x = 70

x = 14

Thus, the value of x is 14 because the sum of all angles in kite is 360 degree option first 14 is correct.
