1. Find the unit rate
15 books divided by 5 days = 3 books sold per day.
Since we are looking for how many days it would take the store to sell 21 bucks, we could do 21 (amount of books) divided by 3 (how much books is sold in a day).
Therefore, it will take a week / 7 days to sell 21 books.
Answer:
Step-by-step explanation:
Supplementary angles add up to 180
∠1 + 50 = 180
∠1 = 180 - 50
∠1 = 130
∠3 +50 = 180 {Supplementary}
∠3 = 180 - 50
∠3 =130
⇒∠1 = ∠3 = 130
Answer:
y-3
Step-by-step explanation:
Answer:
A. 24.5
B. 29.6
Step-by-step explanation:
A.
19 - 13.5 = 5.5
30 - 5.5 = 24.5
24.5 - 5.5 = 19
24.5
B.
43.8 - 36.7 = 7.1
36.7 - 7.1 = 29.6
29.6 - 7.1 = 22.5
29.6
