Answer:
5x+10y+5z
Step-by-step explanation:
Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o

Step-by-step explanation:
Find the LCM of 8,9 and 10.
Prime Factorization to find LCM,
8 = 2 × 2 × 2
9 = 3 × 3
10 = 2 × 5
LCM ( 8 , 9 , 10 ) = 2 × 2 × 2 × 3 × 3 × 5 =360
But 360 is not square
Now we make the pairs complete by multiplying same numbers in prime factorization of LCM.
We need one 2 and one 5 to complete the pair.
We get, Least Square number = 2 × 2 × 2 × 2 × 3 × 3 × 5 × 5 = 3600
Hope this helps
good Luck
Answer:
The situations 1 and 2 describes an equal difference over an equal interval.
Step-by-step explanation:
1. A sunflower grows at a rate of 3.5 cm per day, for the first 28 days.
Here, the growth of the sunflower per day is uniform i.e. 3.5 cm.
2. After the car is purchased the value of a car depreciates at a rate of 15% per year.
Here, also the the depreciation of the car's value is equal i.e. 15% of initial value per year.
3. During an experiment, the amount of bacteria in a culture triples every two days.
Here, the growth of bacteria count is not equal per day because the bacteria count per day increases exponentially. (Answer)
