Mathematics
1 answer:
Zanzabum3 years ago
6 0

Answer:

C; None of the above.

Step-by-step explanation:

Pretend x=1, y=0, and z=2.

You have to match an answer to 1+0-2 (equals to -1).

The first equation would be 2+0+1. When you add them all together you get 3, and that isn't equivalent to -1, so therefore this one is not the answer.

The second equation becomes 1+2+0, and when you solve for the answer, you see that the answer is also 3, and so we can conclude that neither A or B matches with the equation above, so the answer is C, None of the above.

the ratio of girls to boys in an astronomy club was 3:2. there were 30 girls. how many total members were there in the club
lakkis [162]

Answer:

Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42

There are eight girls competing in an ice-skating competition. In how many ways can they finish in first, second, and third plac
docker41 [41]
Since we need to find the number of ways they could enter first, second and third place, (I can't demonstrate, but you should get the idea) take 8, 7 and 6 and multiply them, 5-1 we don't need, we just need 8, 7, and 6, multiply those three numbers and you get 336, there you go, 336 ways to organize all 8 girls in first, second and third place, hope this helps

Solve 4(1-x) + 3x = -2(x + 1)
Tpy6a [65]

Answer:

-2 = x

Step-by-step explanation:

4(1-x)+3x = -2(x+1)      Distribute

4 - 4x + 3x = -2x -2    Combine Like Terms (On the same sides of the equal sign)

4 -x = -2x -2               Combine Like Terms (On different sides of the equal sign)

4 = -3x - 2                   Solve

6 = -3x                        

-2 = x
