Answer 12

Julie is going to a store to buy vases to use as centerpieces at her party. Small vases cost $2 and large vases cost $4. She needs to buy a minimum of 15 vases, and can spend a maximum of $50.

Which system of linear inequalities represents this situation? Let s represent the number of small vases and l represent the number of large vases.

A. s + l ≥ 15

2s +4l ≥ 50


B. s +l ≥ 50

2s + 4l ≤ 15



C. s + l ≥ 15

2s + 4l ≤ 50



D. s + l ≤ 15

2s + 4l ≥ 50

Answer 13

hint: She needs to buy a minimum of 15 vases, and can spend a maximum of $50.

so the inequality representing vase # must be greater than/equal to 15

the inequality representing price must be less than or equal to 50

try to think about this carefully before choosing an answer

C

Answer 15

awesome

Answer 16

Sandy is driving cross country. She has covered 200 miles from the east coast towards the west coast. She has driven this distance in 2 days.

If Sandy continues to drive at this rate, which equation represents the total number of miles , m, she would cover in d more days?

A. m=100d+200


B. m=200d+100



C. m=2d



D. m=300d

Answer 17

if she drove 200 miles in 2 days how much does she travel in one day?

Answer 18

that's 10

Answer 19

not quite

# miles / # of days = ?

Answer 20

3

Answer 21

please re-read the original problem

Answer 22

then find # of miles / # of days

Answer 23

150

Answer 25

# miles/ # of days = ?

Answer 26

200 miles/ 2 of days =

Answer 27

what would that equal? 200/2 = ?

Answer 28

100

Answer 29

good, so she travels 100 miles per day

so the total mile would be

100 * number of days + the 200 already traveled

what equation/ answer choice matches this description?

Answer 30

A

Answer 31

good
