Answer:
37
Step-by-step explanation:
triangles' inside angles always equal 180. so 100+43=143. 180-143=37
2.52 pounds + 1.26 pounds = 3.78 pounds of salad ÷ 18 people = .21 pounds of salad per person
you add the pounds because that is everything she used to make the salad. then you divide by 18 because there are 18 people eating the salad and everyone gets exactly the same amount. Hope this helps :) this should help if you have more questions like this :)
(x pounds + y pounds = total pounds, total pounds ÷ # of people = pounds per person)

Answer:
not really sure for number one
1. 1.56y × 3.9x
2. 4.8x + 9.6y
Samuel needs to estimate the product of 24 x 395.
First method
We round the number to nearest tens
24 can be rounded to 20 because we have 4 on ones place
395 can be rounded to 400 because we have 5 in ones place so we add 1 with 9 and it becomes 10 . so we add 1 with 3 and got 400
20 * 400 = 8000
Second method:
We round the number to nearest hundreds place
24 have no number in hundreds place so it remains 24
395 can be rounded to 400 because we have 9 in tens place.
24 * 400 = 9600
