Answer:

1, 3, 4, 5, 6 are all correct

Step-by-step explanation:

1. x - 2 = 0

+2 +2

solution: x = 2

3. 5 - x = 3

-5 -5

-x = -2 (divide both sides by -1 because x equals 1. A negative divided by a negative equals a positive)

solution: x = 2

4. 10 = 5x (you divide 5 on both sides to get x by itself) 10/5 equals 2 so x=2

5. 1/2x = 1 (you divide both sides so you flip the fraction 2/1 is 2 and 2x1 = 2 so the answer is x=2

6. x^3 = 8 (2x2x2) is equal to 8 so x=2

Answer:

1, 3, 4, 5, 6

Step-by-step explanation:

2 - 2 = 0

2 + 2 = 4, not 2

5 - 2 = 3

10 = 5(2)

1/2(2) = 1

2^3 = 8

1.In a class of 45 pupils ,21play chess and 23 play cards and 5play both games
Mumz [18]

Step-by-step explanation:

(a)

ii.

21 - 5 = 16 play only chess.

iii.

23 - 5 = 18 play only cards

5 play both.

that is 16+18+5 = 39 that play at least one of these games.

i.

so, 45 - 39 = 6 don't play any of these games.

(b)

we have 16+18 = 34 pupils out of 45 that play exactly one game.

so the probabilty to pick one of them is as usual

desired cases / total cases = 34/45 =

= 0.755555555... ≈ 0.76

ValentinkaMS [17]

Answer:

The least number of hours that she would have to work is 11.

Step-by-step explanation:

First, make the equation be "12.75x +100=235". Then, subtract 10 from both sides of the equation. You would get

"12.75x= 135". Then, divide both sides of the equation by 12. 75x, and the equation turns out to say, "x=10.59".
