Answer:
b= 3.5
s= 10.5
p=21
Step-by-step explanation:
b for brush
s for sketch book
p for paint set
b=1/3s
s= 1/2 p
b+s+p=37-2
1/3 s +s+2 s =35
1/3 s +s +2 s =35
10/3 s=35
s= 35*3/10
s= 10.5
b=1/3 s = 10.5/3 = 3.5
s= 1/2 p so p= 2s = 2( 10.5) = 21
10.5+3.5 + 21 = 35
Answer:
Y=5X-7
Step-by-step explanation:
(2,3)
Y-Yo=m(X-Xo)
Y-3=m(X-2)
Y-3=mX-2m
Y=mX-2m+3
(5,18)
18=m(5)-2m+3
18=5m-2m+3
18=3m+3
18-3=3m
15=3m
15/3=m
5=m
Y=5X-2(5)+3
Y=5X-10+3
Y=5X-7
