The answers would be n=5 n+1=6 n+2=7 n+3=8 because the equation is 4n+6=26. You add all the variables and numbers up to get that equation. Then you subtract 6 from 26 to get 20. Finally you divide 20 by 4 to get n=5. To get all the ages you replace n with 5 and complete the equation. For example n+1 is actually 5+1.
It will take him 30-45 minutes to catch up with her. Hope I could help! :)
Answer:

Answer:
yes, yes, no; No
Step-by-step explanation:
We have to assume you have no trouble with single-digit addition and comparison of two numbers.
3+4 > 1 ⇒ 7 > 1 . . . . yes
4+1 > 3 ⇒ 5 > 3 . . . . yes
3+1 > 4 ⇒ 4 > 4 . . . . no
These lengths will not make a triangle because the triangle inequality is <em>not satisfied</em>.

<em>Additional comment</em>
You will notice that we found the result of interest when we added the two smallest numbers (1 and 3) and compared the sum to the largest number (4). This is a shortcut you can use for any "will these make a triangle" question. You don't need to bother comparing larger numbers to smaller ones. You already know they are larger.
Answer:
-3
Step-by-step explanation:
15 = -3(x -2)
-5=x-2
-3=x
