Answer:
either 7 or 8 but, 8 is most likely.
start with the numbers in the set 2,3,4,5,6,7,8
its supposed to be between 2 and 8
the only number that would work is 7 and 8 if you use 7 you get 2 and if you use 8 you get 3
Maria has 19 hats.
b=beth
m=maria
Equations: 2b+5=m
b+m=26
plug in 2b+5 for m in equation 2: b+2b+5=26
add like terms: 3b+5=26
subtract 5 from both sides: 3b=21
Divide 3 from both sides: b=7
now plug in 7 for b: 7+m=26
subtract 7 from both sides: m=19
m=Maria
therefore Maria has 19 hats
