Does each ratio form a proportion?

1: 12/32, 8/3
2: 5.1/1.7, 7.5/2.5
3: 8.5/25, 17/50

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58

8(1/6)

step-by-step explain:

49/6= 48

8 (1/6)

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
