Answer:

the number is 3

Step-by-step explanation:

Perhaps you'd like to find the number.

If n represents the number, we can write the relationship as ...

3n -1 = n +5

Adding 1-n to both sides gives ...

2n = 6

n = 3 . . . . divide by 2

The number is 3.

The product of the number and 3 is 9. One less is 8. That is 5 more than the number itself: 8 = 3 + 5.

the first few steps in solving the quadratic equation 5x2 27x = 14 − 13x by completing the square are shown. 5x2 27x = 14 − 13x

Artist 52 [7]

The best step to do next is to add 80 to both sides of equation:
5 ( x² + 8 x ) + 80 = 14 + 80
and since 80 = 5 · 16
5 ( x² + 8 x + 16 ) = 94 Answer : B )
After that we will continue like this:
5 ( x + 4 )² = 94
( x + 4 )² = 18.8 ... etc
