23/99

Step-by-step explanation:

set up an equation

x = 0.232323...

use elimination

100x = 23.2323...

- (x = 0.232323...)

Somebody please assist me in answering this math question.
Sphinxa [80]
Firstly look at the options carefully and we will get to know that two answer options are incorrect because 2 of them are representing AT MOST SIGN which we don't need. So in that way Options B and D are eliminated.

So Now we are left with 2 options A and C. Lets figure it out.
We know that Carlos has 5 complete set with 4 individual figures and josh has 3 complete sets with 14 individual figures.
So lets write in the numerical language:-
let us assume that complete sets are X.
ATQ,
5x + 4 ≥ 3x + 14
subtracting 3x from both sides.
5x -3x + 4 ≥ 14
2x + 4 ≥ 14
subtracting 4 from both sides
2x ≥ 14 - 4
2x ≥ 10
dividing both sides by 2
x ≥ 5 Answer
So correct answer option is C

Answer:

1. x = -6

2. x = 2

3. x = 6

4. x = 3

5. x = -5

6. x = -1

7. x = 0

8. x = 9

9. x = -4

10. x = 7

Step-by-step explanation:

1.

  • -10x = -8x + 12
  • -10x+8x=-8x+12+8x
  • -2x=12
  • -2x/-2=12/-2
  • x=-6

2.

  • 9-5x+x=1-x+x
  • -4x+9=1
  • -4x+9-9=1-9
  • -4x=-8
  • -4x/-4=-8/-4
  • x=2

3.

  • -2x+16-x=x-2-x
  • -3x+16=-2
  • -3x+16-16=-2-16
  • -3x=-18
  • -3x/3=-18/-3
  • x = 6

4.

  • (-4)(6x)+(-4)(-2)= -8x-40
  • -24x+8=-8x-40
  • -24x+8+8x=-8x-40
  • -16x+8=-40
  • -16x+8-8=-40-8
  • -16x=-48
  • -16x/-16=-48/-16
  • x=3

5.

  • 37 - 8x = (-7)(x)+(-7)(-6)
  • -8x+37=-7x+42
  • -8x + 37 + 7x = -7x + 42 + 7x
  • -x+37=42
  • -x+37-37=42-37
  • -x=5
  • -x/-1=5/-1
  • x=-5

6.

  • 6x+(-2)(2)+(-2)(8x) = 10 + 4x
  • 6x-4-16x = 10 + 4x
  • -10x - 4 = 4x + 10
  • -10x - 4 -4x=4x+10-4x
  • -14x-4=10
  • -14x-4+4=10+4
  • -14x=14
  • -14x/-14=14/-14
  • x=-1

7.

  • (-2)(x) + (-2)(1) = (2)(x) + (2)(-1)
  • -2x-2=2x-2
  • -2x-2-2x = 2x - 2 - 2x
  • -4x - 2 = -2
  • -4x-2+2=-2+2
  • -4x=0
  • -4x/-4=0/-4
  • x=0

8.

  • (-3)(x)+(-3)(3)=(-6)(x)+(-6)(-3)
  • -3x-9=-6x+18
  • -3x-9+6x=-6x+18+6x
  • 3x-9=18
  • 3x-9+9=18+9
  • 3x=27
  • 3x/3 = 27/3
  • x=9

9.

  • 6x-36=(-4)(-2x)+(-4)(7)
  • 6x-36= 8x -28
  • 6x-36-8x = 8x - 28 - 8x
  • -2x-36=-28
  • -2x-36+36=-28+36
  • -2x = 8
  • -2x/-2=8/-2
  • x=-4

10.

  • (2)(x)+(2)(1) = -2x + 30
  • 2x+2=-2x+30
  • 2x+2+2x=-2x+30+2x
  • 4x+2=30
  • 4x+2-2=30-2
  • 4x=28
  • 4x/4=28/4
  • x=7
