Answer:
4.75x=54+2.5x x=24
Step-by-step explanation:
x=Number of games
4.75x=54+2.5x
Subtract 2.5x from both sides:
2.25x=54
Divide both sides by 2.25:
x=24
Answer:
- 8
Step-by-step explanation:
x = - 10
y = 2
I x I
= I - 10 I
= 10
y - I x I
= 2 - 10
= - 8

the correct answer should be (b) 6 is extraneous.
If you look at the second row of the solution you see (x-6) as a factor in one of the denominators. That's a problem: if 6 were a solution this denominator would become 0. But denominators being 0 is bad (undefined), so while 6 comes out of the algebraic manipulation as a solution, it is invalid, or extraneous.
-3 is a fine solution.
Answer:
1/2
Step-by-step explanation:
We first find the least common multiple, which is 6. Therefore, we can multiply 1/3 x 2/2 (since 2/2 is equal to one and won't change the final amount) and get 2/6. 2/6+1/6=3/6, or 1/2.
