Answer:
A
Step-by-step explanation:
a+a+6=42
2a+6=42
subtract 6 on both sides
2a=36
divide 2 on both sides in order to be left with the value of a
a=18
Answer:
24 pounds.
Step-by-step explanation:
a + (a + 6) = 42
a + a + 6 = 42
2a + 6 = 42
2a + 6 - 6 = 42 - 6
2a = 36
a = 36/2
a = 18.
So Barry's bike weighs 18 + 6 = 24 pounds.
