In a necklace the ratio of yellow beads to blue beads is 3:1. What percentage of beads are yellow?
B) 5-x
C) x-5
D) x+5
Answer:
Option (d) is correct.
Selina's age is written as x + 5
Step-by-step explanation:
Given : Amy is 5 years younger than Selina. if Selina's age can be represented by x,
We have to write an expression representing Amy's age.
Since, x represent the Selina's age.
and also Amy is 5 years younger than Selina
that is Amy is 5 years smaller than Selina
So Selina is 5 year older than Amy
So, Selina's age is written as x + 5
