36-x squared i don’t know if it’s right sorry
Answer:
50 cm
Step-by-step explanation:
4/5 = 40/x
cross multiply
4x=200
x=50
1/5 and 1/10
1/5 cannot be broken down anymore.
Therefore, what is equal to or less than 1/10 that 1/5 can reach? 1/10.
1/10 is the least common denominator.
Answer:
3x - 9
Step-by-step explanation:
We already have the expression 4x + 2x − 3x − 9. Now, we just have to add like-terms. This will give us 3x - 9.
The number of CDs in Walter’s collection = x
The number of CDs in Brian’s collection = 3x
The total number of CDs in both collections = 144
Then
x + 3x = 144
4x = 144
x = 36
From the above deduction, we can conclude that the correct option among all the options that are given in the question is the last option or option "J".
