Ok -13*-8 is 104.
-8*18q is 144q.
Combine an you get:
144q+104
5n = 25
divide both sides by 5
n = 5
Answer:
$7.25 = 2.5, so divide by 7.25 by 5 = 1.45 <- better deal & $0.46333333333 per litre.
5.74 = 1.5, so divide 5.74 by 3 = 1.91333333333
Step-by-step explanation:
Why 3 and 5 - 0.5 is 5 times 2.5 and so is 0.5 times 3= 1.5
1.91333333333 - 1.45 = $0.46333333333 per litre.

Answer with explanation:</h2>
Given : Shelly and Kristen share a birthday, but Shelly is 5 years older.
i.e. Age of Shelly = Age of Kristen +5
a. Table show their ages every year, beginning when Kristen was born. :
Kristen Shelly
0 5
1 6
2 7
3 8
4 9
b. If Kristen is 16 years old, then the age of Shelly = 16+5=21
c. If Kristen is K years old, then the age of Shelly = K+5
d. Also, age of Kristen = Age of Shelly - 5
If Shelly is S years old, then the age of Kristen = S-5
