Answer: d. No; Janet could not have won 10 games because 3x ≠ 24.
Step-by-step explanation:
Assume the number of games won by Janet is x. This would mean that the number of games won by Nadia is 2x.
The total number of games played by both would therefore be;
x + 2x = 3x
Janet has won 10 games and we need to find out if the total number of games can be 24 if this is the case.
Expression would therefore be;
3x = 24
x = 10 so;
3(10) ≠ 24
There is therefore no way that they could have played 24 games if Janet had won 10 games. They would have to have played 30 games.
Answer:
The two bottom angles of this triangle are both represented by the same variable, in this case, an x. This means, that both of the bottom angles are equal to each other.
So we have:
32 + x + x = 180 (since the TOTAL angles of a triangle adds up to 180)
32 + 2x = 180 (combine the 2 x's together)
2x = 148 (subtract a 32 from both sides)
x = 74

1/8 because you have to break it down using order of operations. An alternative is 0.125,2 to the negative third power.
The right equations are a+c=30 (total number of people) and 8a+c=100 (total amount of money). So answers B and D cannot be right.
a+c=30 can be rewritten as c=30-a and filled into the second one:
8a + 30-a = 100 => 7a = 70 => a=10
That leaves answer A as the right one.
