A. d=45t
b. 112.5 miles. 112.5=45•2.5
x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.
Step-by-step explanation:
Let,
x be the gift wrapped with wrapping paper.
y be the gifts in gift bag.
Time for wrapping one gift = 6.5 minutes
Time for doing 1 gift bag = 3 minutes
Total gifts = 19
Total time = 74.5 minutes
According to given statement;
x+y=19
6.5x+3y=74.5
x+y=19 and 6.5x+3y=74.5 can be used to determine the number of gifts wrapped and number of giftbags prepared where x represents the wrapped gifts and y represents giftbags.
