<span>y^8 = 4
y^7 = 3/x

y(y^7) = 3/x(y)
y^8 = 3y/x

3y/x = 4
3y = 4x
y = 4x/3

If you run a marathon of 26 1/5 miles in a time of 5 4/5 how far do you run in 1 hour<br><br>pls
alisha [4.7K]

First let's make both the miles and the hours ran improper fractions:

26+\frac{1}{5}=\frac{131}{5}\\ 5+\frac{4}{5}=\frac{29}{5}

So, to find our miles per hour, we have to divide the miles by the hours to get: \frac{\frac{131}{5}\text{miles}}{\frac{29}{5}\text{hours}}=\frac{131\text{miles}}{29\text{hours}} \\ \text{ Now we have to divide the top and the bottom by 29 to get our miles per hour so: }\\ \frac{\frac{131}{29}}{\text{hour}} \approx \frac{4.52 \text{miles}}{\text{hour}}

Draw a conclusion is the statment below always, sometimes, or never true ? Bive at least two examples to support your reasoning.
lions [1.4K]

Answer:

Sometimes

Step-by-step explanation:

Example 1:

Take two numbers as 7,8

LCM of 7,8=7(8)=56

In this case, the lcm of two numbers is equal to the product of the two numbers.

Example 2:

Take two numbers as 6,3

6=3(2)

So,

LCM of 6,3=3(2)=6

In this case, the lcm of two numbers is not equal to the product of the two numbers.

Therefore,

Sometimes, the lcm of two numbers is equal to the product of the two numbers.
