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.)

8 -<u> 8</u>, 16, 24, 32, 40, 48  

4 - 4, <u>8</u>, 12, 16,

So the LCM of 8 and 4 are C) 8

8 - 8, 16, <u>24</u>, 32, 40, 48

6 - 6, 12, 18,<u> 24</u>, 30

So the LCM of 8 and 6 are A) 24

8 - 8, 16, 24, 32, <u>40</u>, 48

10 - 10, 20, 30, <u>40</u>, 50

The LCM of 8 and 10 are B) 40

Hope this Helps!!

At a restaurant, you order a meal that costs $8. you leave a 15% tip. the sales tax is 6%. what is the total cost of the meal?

Easy! multiply the 6% by $8 then add it to the $8, now, multiply the 15% by the total of the cost with tax. then you all that to the total. ($9.75)

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. One of the x-interc
Marina CMI [18]
3x^2 + 6x - 10 = 0
3(x^2 + 2x) - 10 = 0
3[ (x + 1)^2 - 1 ] - 10 = 0
3(x+1)^2 - 13 = 0

so the vertex is at (-1,-13)
the roots will be same distance from x = -1
that is a distance 1.08 --1 = 2.08

so other root is approximately  -1 -2.08 = -3.08

the other intercept is at (-3.08,0)
