There are 8 problems in the picture.  What you need is for someone to give you
some tips and solve one or two of them. 
Giving you a bunch of answers and nothing else does NOT help you.

Here are my tips to you:

A).  You're always trying to find the number that the unknown letter must be equal to,
in order to make the equation a true statement.  That's the solution to the equation,
and the 'answer' to the problem.  

B).  Always do what you have to do in order to get the letter all by itself on one side.

C).  Whatever you do to one side of the equation, you must do to the other side.

==========================================

Examples, from the picture:

<u>#3:</u>  <u>8x - 2 = -9 + 7x</u>    What can you do to get the 'x' all alone on one side?

Subtract 7x from each side:    x - 2 = -9

Add 2 to each side:            <u>x = -7</u>
===========================================
<u>#2:</u>  <u>6 = 1 - 2n + 5</u>  

Combine the 1 and the +5 on the right side:      6 = 6 - 2n

What can you do to get the 'n' all alone on one side?

Subtract 6 from each side:      0  =  - 2n

Divide each side by -2 :      <u> 0 = n</u>
===========================================
<u>#5:</u>  <u>4m - 4 = 4m</u>

Subtract 4m from each side:    - 4 = 0

There is no number for 'm' that can make -4 equal to zero.
So this equation has <u>no solution</u>.
(That's OK.  Not every equation must have a solution.)

I need helpp!!!!!!!!!!!!

Hey,
We can see here 2 of the angles are equal and the third one is a right angle right?
That means it is an isosceles triangle since they have 2 equel angles and a right anlgle.

Another feature of the isosceles triangle is that 2 sides are equal.
We are given one side is 5.5 right?
So the side BC has to be 5.5 or the side AB has to be 5.5
In isosceles triangles the side opposite to the 90 degree angle is the hypotenuse.This means it is the longest angle.
So it has to be AB which is equal to 5.5 since BC is the hypotenuse.

Hope this helps,Happy New Year

Estimate the sum to the nearest whole number <br><br> 29.1 +78.9 + 41.5
lesya692 [45]

I rounded each number to the nearest whole number and added those.

29 + 79 + 42 = 150

If you add the original numbers you would get 149.5, which rounds to 150.

Prove that the value of the expression<br> (16^3–8^3)(4^3 +2^3) is divisible by 63.
Darya [45]

Answer:

Step-by-step explanation:

16^3 - 8^3

Take out 8^3 as a common factor.

16^3 = 2^3 * 8^3

8^3(2^3 - 1)  

8^3(8 - 1) = 8^3 * 7

(4^3 + 2^3)     Expand

64 + 8            Combine

72

72 = 9 * 8

Conclusion

(8*3 * 7 )(9*8)

7*9 = 63

So any number containing 63 will divide into the reduced form of

(16^3–8^3)(4^3 +2^3)

the spoke of a wheel reaches from the center of the wheel to its rim. If the circumstances of the rim of the wheel is 42 inches,
jekas [21]
The spoke of the wheel serves as the radius of the circle. 
To solve for the circumference of the circle, we use this formula:

C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r 
6.69 inches = r

The length of each spoke is 6.69 inches.
