if n is an odd number, then the lcm of n and 8 is n×8. The given condition is true.
What is LCM?It is defined as the common number of two integers, which is the lowest number that is a multiple of two or more numbers. The full name of LCM is the least common multiple.
It is given that,n is an odd number, then the lcm of n and 8 is n×8.
Whole numbers that cannot be split precisely into pairs are known as odd numbers. When two odd numbers are divided, the result is one.
We have to take some of the odd numbers in order to examine the condition,
n=1,3,5,7,11
Examine by taking the value of n,
n=1
Lcm of 1 and 8 is 8.
n=3
3=3×1
8=2×2×2
Lcm of 3 and 8 is 24.
n=5
Lcm of 5 and 8 is 40.
n=7
Lcm of 7 and 8 is 56.
n=9
Lcm of 9 and 8 is 56.
n=11
Lcm of 11 and 8 is 88.
Thus, if n is an odd number, then the lcm of n and 8 is n×8. The given condition is true.

Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?”
Jada writes this equation for the sum of the ages:
(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87
Match the meaning to each term of the equation.
x
x + 3
(x - 2)
3(x + 3) - 1
87
Answer:
x = 13
Andre is 13, Andre's brother is 16, Andre's sister is 11, Andre's mom is 47
Answer:
x = 13
Andre is 13
Brother is 16
Sister is 11
Mom is 47
All together they are 87!
Step-by-step explanation:
x + x + 3 + x - 2 + 3x + 9 - 1 = 87
6x + 9 = 87
6x = 87 - 9
6x = 78
x = 78/6
x = 13

The child’s actual height is 1.3 m.
What is the actual height of the parent?

Tania measured the growth of her plant each week. The first week, the plant's height measured 4.78 decimeters. During the second week, Tania's plant grew 0.7 decimeter.
How tall was Tania's plant at the end of the second week? Complete the description of the steps to solve the problem.
From rounding each number to the nearest whole number, an estimate of the sum is about (______)
decimeters. Then add 4.78 and 0.7. Write an equivalent decimal for 0.7 so the addends have the same number of decimal places. Add the hundredths, then the tenths. Regroup 10 tenths as 1 one, and add the ones. At the end of the second week, Tania's plant was
decimeters tall.
The answer is close to the estimate so the answer is (______)
Answer:ahem, I'm sorry but the education system sucks, I would straight up tell my teacher that.
just add 4.78 + 0.7 and ta-da! 5.48 is your final answer.

We can easily determine that on the line number:
There are 3 units from 0 to 3.Then there are another 3 units from 3 to 6.In other words, there are 2 sets of 3 units.
Hence,
2 x 3 = 6 should be right answer.
Therefore, option (A) is true.
