Hope this helps :)

Answer:

a = -1/2

Step-by-step explanation:

-1/4a - 4 = 7/4a - 3

-a/2^2 - 4 = 7/ 2^2 a - 3

(-a) - ( 2^2) 4 / 2^2 = 7a/ 2^2 - 3

a = -1/2

I know this confusing but this how I got the answer.

There is No Congruence between Two Triangles.

If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create an identical appearance. If moved, they coincide with one other.

Given:

By seeing Two Triangles, We have two sides Equal.

But, there is no third part of Congruence here.

Hence, there is No Congruence between Two Triangles.

a = 14.73

Step-by-step explanation:

This ratio can also be written like this:

[tex]\frac{a}{27} = \frac{6}{11}[/tex]

Then you can cross multiply to get

11a = 6 x 27

11a = 162

Divide both sides by 11

11a / 11 = 162 / 11

Use a calculator or chart to find the z-score.

P(Z > z) = 0.60

P(Z < z) = 0.40

z = -0.253

Find the time associated with the z-score.

z = (x − μ) / σ

-0.253 = (x − 4) / 3

Hello!!!

I can understand how you feel about this. I hope to do my best in helping you understand quadrant numbering and signs.

Now for the number start form the top right and move counter-clockwise, that is

Top right =1st quadrant

Top left = 2nd quadrant

Bottom left = 3rd quadrant

Bottom right =4th quadrant

Basically moving counter-clockwise you will get this

Now for the sign convection

Up and right are both positive

Down and left are both negative.

I hope this helps. Don't forget to let me know should you need any further assistance.
