Can someone explain how to answer this

60-30=30×40=70-80=-10

if the number of negatives are even they are always positive. if the number is odd of negatives. it always is negative. -- = + --- =-

Answer: 6

Answer: Let's solve your equation step-by-step.

2h−3=3

Step 1: Add 3 to both sides.

2h−3+3=3+3

2h=6

Step 2: Divide both sides by 2.

2h/2 = 6/2

h = 3.

use the distributive property

combine alike terms

add the negative number to the other side

combine alike terms

then divide on both sides to get the variable by itself

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.

I hope this helps

Step-by-step explanation:

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.

Regards.

Answer:

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

a = 14.73

Answer:

neither,  i think

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.

Answer:

  2) 162°, 72°, 108°

  3) 144°, 54°, 126°

Step-by-step explanation:

1) Multiply the equation by 2sin(θ) to get an equation that looks like ...

   sin(θ) = <some numerical expression>

Use your knowledge of the sines of special angles to find two angles that have this sine value. (The attached table along with the relations discussed below will get you there.)

____

2, 3) You need to review the meaning of "supplement".

It is true that ...

  sin(θ) = sin(θ+360°),

but it is also true that ...

  sin(θ) = sin(180°-θ) . . . . the supplement of the angle

This latter relation is the one applicable to this question.

__

Similarly, it is true that ...

  cos(θ) = -cos(θ+180°),

but it is also true that ...

  cos(θ) = -cos(180°-θ) . . . . the supplement of the angle

As above, it is this latter relation that applies to problems 2 and 3.

Answer:

6.4 units

Step-by-step explanation:

c = √(x1 - x2)^2 + (y1 - y2)^2

c = √(3 - 7)^2 + (-3 + 8)^2

c = √(-4)^2 + (5)^2

c = √16 + 25

c = √41

c = 6.4031...

c = 6.4

Answer:

3.24 minutes

Step-by-step explanation:

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

x = 3.24
