Clue #1 the total number of unicycles, bicycles and tricycles is 38. Clue #2 There are more tricycles than bicycles and unicycles combined. Clue #3 One-half the number of tricycles is two less than the number of bicycles. clue #4 The total number of wheels is divisible by 3. Clue #5 The number of tricycle wheels is 10 times the number of unicycle wheels. 1. Write a system of equations to determine the number of unicycles, bicycles and tricycles in the bike store.
2. How many of each type of bike is in the store?

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

a is the correct

d
