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:
Answer:
$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
