The x represents how many songs Sabrina has because if you are saying Nicolas has three less than twice as many as her then you are doubling the amount of songs Sabrina has and you're subtracting 3 from that to get how many songs Nicolas has. Let's say Sabrina has 29 songs. Now we are trying to find out how many songs Nicolas has. 2x-3. 2(29) - 3. 58-3. Nicolas has 55 songs if Sabrina were to have 29. I really hope this helped :)
Answer:
c=45
Step-by-step explanation:
by the pythagorean theorem, c = sqrt(3^2+6^2) = sqrt(9+36) = sqrt(45)
Therefore, c=45.
Hey there! :)
Answer:

-1/5n + 7 = 2
Start by subtracting 7 from both sides:
-1/5n + 7 - (7) = 2 - (7)
-1/5n = -5
Multiply both sides by the reciprocal of -1/5, or -5.
(-5) · (-1/5n) = (-5) · (-5)
n = 25
Assuming the variables are constants, you isolate m. So move am to the left. K-am=emx. Now divide ex. This gives you, m=(K-am/ex)
The distance: use absolute value
Between x and 8: x-8
The distance between x and 8: | x-8 |
“is no more than” means it can be that or be less than that, so use ≤
The distance between x and 8 is no more than 4
| x-8 | ≤ 4
