Answer 1

30)–2(7x - 3) – x = 2(3x - 2) – 3
-14x+6-x=6x-4-3
-15x+6=6x-7
13=21x
Answer C

31)i'd guess ABDEF

32)-4x - 9 + 3(2x + 5) - 2
-4x-9+6x+15-2
2x+4
2x=-4
x=-2

33)122
Answer E

34)3x - 4 = 17
3x=21
x=7

36)7x - 15 = 5x – (4x + 3)
7x-15=5x-4x+3
7x-15=x+3
6x=18
x=3
Answer D

41)Again a guess at ABDEF

Answer 2

Quite a homework. Lets see.

30) -2(7x - 3) - x = 2(3x - 2) - 3
-14x + 6 - x = 6x - 4 - 3
- 15x + 6 = 6x - 7
6 + 7 = 6x + 15x
13 = 21x


x = 13/21 = 0.619047·
A) 9x = -1 then x = -1/9 = - 0.1·
B) 14x -6 = - 6x + 4 then 20x = 10 x = 1/2 = 0.5
C) -15x +6 = 6x - 7 then -21x = -13 x = 13/21 = 0.619047·
D) -15x - 6 = 6x - 10 then -21x = -4 x = 4/21 = 0.190476·
E) 15x - 3 = 6x - 5 then 9x = -2 x = -2/9 = -0.2·
F) Non of the above.
We had: C) x = 13/21 = 78/126 = 0.619047·
B) x = 1/2 = 63/126 = 0.5
D) x = 4/21 = 24/126 = 0.190476·
A) x = -1/9 = -14/126 = - 0.1·
E) x = -2/9 = -28/126 = - 0.2·
I suppose F) can be solved by making an equation where x has a different value from A) B) C) & D), but, if collect by terms means there must be a relationship between them; you'll see that, expet them are all values = n/126, there's no other one. So lets choose for x 126/126 = 1 Then
15.1 - 6 = 3.1 + 6 9 = 9
15x - 6 = 3x + 6 12x =12 x = 1 = 126/126

31) 0 is: A B D E F. When D: area = 0

32) - 4x - 9 + 3(2x + 5) - 2
- 4x - 9 + 6x + 15 - 2
2x + 4 = 2(x + 2)

33) A = 225 = 15^2
B = 196 = 14^2
C = 169 = 13^2
D = 144 = 12^2
121 = 11^2; but,
E = 122 is not a perfect square

34) 3x - 4 = 17
3x = 21 so x = 7

35) x = x

36) 7x - 15 = 5x - (4x + 3)
7x - 15 = 5x - 4x - 3
7x - 15 = x - 3
6x = 12 then x = 2

41) 4 is: A, B, D, E, & E

Answer 3

I'll help you with number 33.

A perfect square is some number multiplied by itself.

Try multiply 10 x 10.
Now try 11 x 11.
Now 12 x 12.

Cross off the numbers on the list that you find. Keep going until you're producing numbers that are too big for the list.

Answer 4

30
-15x + 6 = 6x - 7

31
A, B, D, E

32
2x+4

33
122

34
x = 7

36
x = 3

41
A, B, D, E, F

Answer 5

You're lazy! Its taken you longer to type in these problems than if you would just do them yourself. How in the world do you plan on passing the tests if you can't (or more likely, WON'T) do your own homework.

If I was your parent and found out about this I would take away the use of the internet from you.

Answer 6

33.) e )122
34.)3x-4=17
3x=17+4
3x=21
x=21/3
x=7
sorry im too old to remember the rest

Answer 7

number 33 is e)122

Answer 8

i am very sorry but i do not know about math all that well which math is it ?
applied or sumthin not good taking consumer sry

Answer 9

You've got to be kidding. No way am I giving you the answers. NO WAY!

Answer 10

Sorry If I told you how- how will you learn? don't be so lazy and do it yourself.
