1. Are there more inches in a mile or second in a day?​
Sedaia [141]

Answer:

Step-by-step explanation:

60 x 60 = 3600

3600 x 24

5280 x 12

I know for steps 2 and 3 to be equal, 3600 would have to be half of 5280 because 24 is twice 12, and it’s not. And because 3600 is more than half of 5280, I know that 3600 times 24 is more than 5280 times 12. My answer, therefore, is there are more seconds in a day.

If f(n) n2 - 2n, then f(2) = 0. True.or.False?
Lady_Fox [76]

Answer:

True

Step-by-step explanation:

So we know that:

f(n)=n^2-2n

And we are asked to verify whether f(2)=0 is true or false.

To determine the answer, substitute 2 for n in the function and solve. So:

f(2)=(2)^2-2(2)

Square and multiply:

f(2)=4-4

Subtract:

f(2)=0

So, the statement is indeed true.

And we're done!

Can anyone explain the method for algebraic fraction? We have to do it for maths, and i'm really struggling with it. Here is an
riadik2000 [5.3K]

Answer:

x=3

Step-by-step explanation:

The approach is not very different from regular fractions.

You have to get to a common denominator to be able to add them.

10 is a good denominator (multiply the denominators).

multiply the first term by 5, and the second one by 2:

\frac{5 \cdot (x+1)}{5 \cdot 2} + \frac{2 \cdot (x+2)}{2 \cdot 5}  = 3

\frac{5x+5 + 2x+4}{10} = 3

\frac{7x+9}{10} = 3

7x + 9 = 30

7x = 30 - 9

x = 3

let me know if you need more details on one of the steps
