Find The Value Of X That Makes ADEF - AXYZ.62x - 5F2214IZ12X

Answers

Answer 1

Answer:

x = 8

Step-by-step explanation:

For the triangles to be similar then the ratio of corresponding sides must be equal, that is

[tex]\frac{DF}{XZ}[/tex] = [tex]\frac{EF}{YZ}[/tex] , substitute values

[tex]\frac{2x-5}{22}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )

12(2x - 5) = 132 ( divide both sides by 12 )

2x - 5 = 11 ( add 5 to both sides )

2x = 16 ( divide both sides by 2 )

x = 8

help please in this question?

Answers

Answer:

see explanation

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and are supplementary, sum to 180° , so

5x + x + 54 = 180 ← equation to solve to find x

6x + 54 = 180 ( subtract 54 from both sides )

6x = 126 ( divide both sides by 6 )

x = 21

Then

∠ 1 = 5x = 5 × 21 = 105°

∠ 2 = x + 54 = 21 + 54 = 75°

karrie was late to work 14 times last year if she worked 250 days last year what percent of the days were she late

Answers

not sure if it's right
250 days = 100%
14 days = ?%
1 day = 100/250 = 0.4%

Therefore 14days = 0.4% • 14 = 5.6 %

A rectangle has a length of y^2+3y+7 and a width of y-3. How much longer is the length?

Answers

Given:

The length of the rectangle = [tex]y^2+3y+7[/tex]

Width of the rectangle = [tex]y-3[/tex]

To find:

How much longer is the length?

Solution:

We need to find the difference between length and width of the rectangle.

[tex]Difference=Length-Width[/tex]

[tex]Difference=y^2+3y+7-(y-3)[/tex]

[tex]Difference=y^2+3y+7-y+3[/tex]

[tex]Difference=y^2+(3y-y)+(7+3)[/tex]

[tex]Difference=y^2+2y+10[/tex]

Therefore, the length of the rectangle is [tex]y^2+2y+10[/tex] much longer than the width.

Write an equation of a line in slope-intercept form that has a slope of -5 and passes through the point (-3, -4).

Answers

Answer:

y = -5x - 19

(-15, 0) and (-21, -2).
A) Do the lines intersect? Show work to prove it! Grcle YES or
NO

Answers

Answer:

Step-by-step explanation:

Find the slope of each line. If the slopes are the same, the lines are parallel. Otherwise, the lines intersect.

Slope of line passing through (x₁, y₁) and (x₂, y₂) = (y₂-y₁)/(x₂-x₁)

Slope of line passing through (0, 5) and (-6, 3) = (3-5)/(-6-0) = ⅓

Slope of line passing through (-15, 0) and (-21, -2) = (-2-9)/(-21-(-2)) = 11/19

The lines intersect.

Answer:

a) IJ is median

IJ = 1/2(HG + EF)IJ = 1/2(8 + 12) = 10 cm

b) I is midpoint of HE, therefore, HI = IE

Substitute values and solve for x:

10 = x - 4x = 10 + 4x = 14 cm

Answer:

a) IJ is median

IJ = 1/2(HG + EF)

IJ = 1/2(8 + 12) = 10 cm

b) I is midpoint of HE, therefore, HI = IE

Substitute values and solve for x:

10 = x - 4

x = 10 + 4

x = 14 cm
