isosceles trapezoid
trapezoid
rhombus
square
rectangle
parallelogram
quadrilateral
10x+18+62=180 co interior angle

10x=180-80

x=100/10=10

:.x=10

8x+2=7x+14 corresponding angle of parallelogram are equal

8x-7x=14-2

x=12

10.

4x+4=5x+1 corresponding sides of parallelogram are equal

4-1=5x-4x

x=3

11.

4+3x=19corresponding sides of parallelogram are equal

3x=19-4

x=15/3

x=5

X + 11 < 6 <br> Solve and graph on a number line

Drupady [299]

Answer & Step-by-step explanation:

So I can't exactly graph exactly, but I'll try...

To solve:

x+11<6 Subtract 11 on both sides.

x<-5

To graph:

<-------|---------o---------|-------->

-6 -5 -4

(The bolded part of the line is the side you shade the graph on. In case you can't see it, you have to shade the left side of the open circle.)

Hope this helps! Have an awesome day ( • ω • )^

What is the equation of a line that is parallel to 4x+6y+5=0 and passes through the points (6,9)

OLga [1]

Step-by-step explanation:

Equation of given line is:

$4x+6y+5=0 \\ \therefore \: 6y = - 4x - 5 \\ \\ \therefore \: y = \frac{ - 4x - 5}{6} \\ \\ \therefore \: y = \frac{ - 4x}{6} - \frac{5}{6} \\ \\ \therefore \: y = - \frac{ 2}{3}x - \frac{5}{6}...(1) \\ equating \: eq \: (1) \: with \: y = mx + c, \:we \:\\ find : \\ slope \: of \: given \: line \: (m) = - \frac{ 2}{3} \\ \because \: required \: line \: is \: \parallel \: to \: given \: line \\ \therefore \: slope \: of \: required \: line \\ = slope \: of \: given \: line \: (m) = - \frac{ 2}{3} \\ \because \: required \: line \: passes \: through \: \\ point \: (6, \: 9) \\ \therefore \: \: equation \: of \: line \: in \: slope \: point \: \\ form \: is \: given \: as: \\ y-y_1=m(x-x_1) \\ \therefore \:y - 9 = - \frac{ 2}{3}(x - 6) \\ \therefore \:3(y - 9 )= - 2(x - 6) \\ \therefore \:3y - 27= - 2x + 12 \\ \therefore \:2x + 3y - 27 - 12 = 0 \\ \purple{ \boxed{\therefore \:2x + 3y - 39 = 0}} \\ is \: the \: equation \: of \: required \: line$

A student skipped a step when she tried to convert 18 hours into seconds,

gladu [14]

Answer:

The conversion of minutes to seconds is skipped in multiple-step conversion.

Step-by-step explanation:

Given:

To convert 18 hours into seconds.

Now, to get the conversion ratio skip in this multiple-step conversion.

First we need to convert hours into minutes:

1 hour = 60 minutes.

So, 18 hours = $18\times 60 minutes$

= $1080 minutes$ .

Then, we convert minutes into seconds:

1 minute = 60 seconds.

So, 1080 minutes = $1080\times 60 seconds$

= $64800 seconds$ .

Thus, 18 hours = 64800 seconds.

<u>As given in question the conversion from hours to seconds is there but the conversion of minutes to second is not there it is skipped so the result is incorrect.</u>

Therefore, the conversion of minutes to seconds is skipped in multiple-step conversion.
