Answer:
I wanna say 7 but I could be wrong
Step-by-step explanation:
The number of triples is 6.
A Linear Equation is an equation of a line. An equation in which the highest power of the variable is always 1. An equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.
For the given situation,
Total number of hits = 18
Doubles + triples = 18
Let x be the number of triples. Then
Number of doubles = 18-x
Number of bases for doubles = 2 bases
Number of bases for triples = 3
The equation for the above situation is
⇒ [tex]2(18-x)+3x=42\\[/tex]
⇒ [tex]36-2x+3x=42[/tex]
⇒ [tex]x=42-36[/tex]
⇒ [tex]x=6[/tex]
Hence we can conclude that the number of triples is 6.
