Answer:
4th option
Step-by-step explanation:
The term that combines with 3x²y , must have variables x²y
The only other term with x²y is 8x²y
Answer:
s = 10500
Step-by-step explanation:
s/5 + 125 = 2225
Our mission is to isolate s. We can first begin to do this by subtracting 125 from both sides.
s/5 + 125 - 125 = 2225 - 125
s/5 = 2100
Since s is being divided by 5, we can multiply by 5 on both sides to get s alone.
s/5 x 5 = 2100 x 5
s = 10500
1. Decompose all numbers into prime factors
300 2 150 2 75 3 25 5 5 5 1 400 2 200 2 100 2 50 2 25 5 5 5 1 500 2 250 2 125 5 25 5 5 5 1
2. Write all numbers as the product of its prime factors
Prime factors of 300 = 22 . 3 . 52
Prime factors of 400 = 24 . 52
Prime factors of 500 = 22 . 53
3. Choose the common and uncommon prime factors with the greatest exponent
Common prime factors: 2 , 5
Common prime factors with the greatest exponent: 24, 53
Uncommon prime factors: 3
Uncommon prime factors with the greatest exponent: 31
4. Calculate the Least Common Multiple or LCM
Remember, to find the LCM of several numbers you must multiply the common and uncommon prime factors with the greatest exponent of those numbers.
LCM = 24. 53. 31 = 6000
Answer:
7/8 = 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8 + 1/8
7/8 = 1/8 + 6/8
7/8 = 4/8 + 3/8
7/8 = 5/8 + 2/8
Step-by-step explanation:
Hope it helps!
