5hockey pucks and 3 hockey sticks cost $23. 5 hockey pucks and 1 hockey stick cost $20. how much does 1 hockey puck cost?

Answe

5p + 3s = 23

5p + s = 20

s = 20 - 5p

5p + 3(20-5p) = 23

5p - 60 - 15p = 23

-10p = - 37

p = 3.70

s = 1.50r

Step-by-step explanation:

$3.65

Step-by-step explanation:

let say hokey puck=p, hockey sticks=s

5P+3s=23.5

5p+1s=20, subtract first one from the second one:

5p+3s-5P-1s=23.5-20

2s=3.5

s=3.5/2=1.75  now substitute this to any of the equations:  5p+1x1.75=20  5P+1.75=20  5p=20-1.75  5p=18.25  p=3.65

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
