Lesson 9: Representing Proportional Relationships with Equations
Exit Ticket
Oscar and Maria each wrote an equation that they felt represented the proportional relationship between distance in
kilometers and distance in miles. One entry in the table paired 152 km with 95 miles. If k represents the number of
kilometers and m represents the number of miles, who wrote the correct equation that would relate kilometers to
miles? Explain why.
1.6
Oscar wrote the equation k = 1.6m, and he said that the unit rate represents kilometers per mile.
Maria wrote the equation k 0.625m as her equation, and she said that 0,625 represents kilometers per mile.

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

70

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
