Find the value of x that makes Triangle DEF~ triangle XYZ.

Answers

Answer:

x = 4

Step-by-step explanation:

DE / XY = EF / YZ

5 / 10 = 2x-1 / 14

cross-multiply:

10(2x-1) = 14(5)

20x - 10 = 70

20x = 80

x = 4

The ratio of their corresponding side will remain constant. Then the value of x is 4.

What is the triangle?

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The two triangles are ΔDEF and ΔXYZ.

It is given that the ΔDEF and ΔXYZ are similar.

Then the ratio of their corresponding side will remain constant. That is

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]

From the first two, we have

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]

On simplifying, we have the value of x

x = 4

Step-by-step explanation:

1. Isolate x: move 5 to the otherside

=> -2x-6=4*5 => -2x-6=20

2. Move 6 to the otherside: -2x=20+6 => -2x=26

3. Divide both sides by -2

Answers

Answer:

Step-by-step explanation:

if 45+47=t and t=45+47    t would equal 92 in both

45+47<t than t<45+47

so basically its saying 92<t (92is less than t)  and t<92 (t is greater than 92)

he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92

Answers

Answer:

3.9375 hours

Step-by-step explanation:

Working alone it takes mark 7 hours to mop the whole house it takes sue 9 determine to the nearest hundredth of the hour how long it will take then to mop the house together

This is calculated as

1/Time it would take them to work together = 1/ Number of hours Mark mopped + 1/ Number of hours Sue mopped

= 1/T = 1/7 + 1/9

Lowest common denominator = 63

1/T = 9 + 7/63

1/T = 16/63

T = 63/16
