The first one is a valid proportion because when simplified they equal the same

(3/4 is simplified, and 21/28 can be simplified by dividing both the numerator and denominator by 7, you get 3/4 which is equal to 3/4)

Miriam is going to the county fair. Each ride ticket costs $2 and admission costs $7. Miriam has $25 to spend at the fair.

Talja [164]

Answer:

Step-by-step explanation:

Given data

Ride ticket= $2

Admission= $7

Amount= $25

We want to find the greatest number of rides

let the number of rides be x

The expression to describe how she spends the amount is given as

y=7+2x

for y= 25, let us find x

25= 7+2x

25-7= 2x

18=3x

x= 18/2

x= 9

Hence the number of rides is 9
