The sum of two numbers is 10 and the difference is 6. What are the numbers? Create a new system of two linear equations using the methods described in part (i) of the Exploratory
Challenge. Verify that the new system has the same
solution.

70

step-by-step explanation:

i think the amount would be $140.62

50-60=10

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.
