Answer: Lela's original score was 16.
Step-by-step explanation:
Alright lets get started.
Suppose Lela score was L.
Suppose Pepe score was P.
The ratio of Lela’s game score to Pepe's score is
So the equation will be
Cross multiplying
.................equation 1
Then Lela completes a quest and scores 12 bonus points. The new ratio becomes
Cross multiplying
Plugging value of P from equation 1
Hence the score of Leela originally was 16. Answer

4
Step-by-step explanation:
If the two numbers are 'a' and 'b', the sum of their reciprocals is ...
The sum of their reciprocals is 4.
Answer:
see explanation
Step-by-step explanation:
(a)
y = - bx
substitute y = 6 , x = 1 into the equation
6 = a - b → (1)
substitute y = 0 , x = 2 into the equation
0 = - 2b ( multiply through by 2 to clear the fraction )
0 = a - 4b → (2)
multiply (1) by - 4
- 24 = - 4a + 4b → (3)
add (2) and (3) term by term to eliminate b
- 24 = - 3a + 0
- 24 = - 3a ( divide both sides by - 3 )
8 = a
substitute a = 8 into (1) and solve for b
6 = 8 - b ( subtract 8 from both sides )
- 2 = - b ( multiply both sides by - 1 )
2 = b
Then a = 8 and b = 2
(b)
when x = 4
y = - 2(2) = 2 - 4 = - 2
