Answer:
Jaylen was 16 years old. She's the oldest.
Step-by-step explanation:
16 Jaylen
15 sibling 1
14 sibling 2
13 sibling 3
12 sibling 4
11 sibling 5
10 sibling 6
____________
91 Total
My thinking was that I started out dividing 91 by 7. That came out 13. So I knew the oldest one had to be older than 13.
Answer: the two numbers are 7 and -27
Step-by-step explanation:
Let the two numbers be a and b
From the question,
a + b = -27.......eqn 1
a - b = 41............eqn 2
Sum the two equations
2a = 14
Divide both sides by 2
a = 14/2; a = 7
Substitute a = 7 into equation 2
a - b = 41
7 - b = 41
Make b the subject of the equation
-b = 41 -7
-b = 34
b = -34
Check:
a + b = -27, slot the values of a and b
7 + (-34) = -27
7- 34 = -27
