Answer: Amy Doesn´t have enough flour left over to make 3 pots of potato soup.
Step-by-step explanation:
Hi, the complete question is:
Amy has 30 grams of flour. She puts 4 grams of flour in each pot of chowder that she makes. She puts 5 grams of flour in each pot of potato soup that she makes. She makes 4 pots of chowder. Does Amy have enough flour left over to make 3 pots of potato soup?
So, if she makes 4 pots of chowder and each one needs 4 grams of flour:
4 x 4 = 16 grams of flour
Now, to make 3 pots of potato soup, she needs 5 grams of flour for each pot.
3 x 5 = 15 grams of flour
Amy has 30 grams of flour; we have to subtract the grams used for the pots of chowder (16) to obtain the flour left.
30-16 = 14 grams of flour left
Since she needs 15 grams for the 3 pots of potato soup, Amy Doesn´t have enough flour left over to make 3 pots of potato soup.
Because 14 < 15
B
up means positive, so up 7 floors is +7
the opposite of -7 is +7
Create 2 equations for the given problem
12s + 44c = 42
44s + 12c = 30
Take either equation and solve for either s or c.
12s + 44c = 42
12s = 42 - 44c
s = (42 - 44c) / 12
s = (21 - 22c) / 6
Substitute into 2nd equation
44s + 12c = 30
22((21 - 22c) / 3) + 12c = 30
22(21 - 22c) + 36c = 90
-448c +462 = 90
-448c = -372
c = -372/-448
c = 93/112
c = 0.83
Substitute into the 2nd equation
44s + 12c = 30
44s = 30 - 12c
s = (30 - 12 (93/112)) / 44
s = (30 - 279 / 28) / 44)
s = (30 - 9 27/28) / 44
s = 0.46
Prove
12s + 44c = 42
12(0.46) + 44(0.83) = 42
5.52 + 36.52 = 42
42.04 = 42
44s + 12c = 30
44(0.46) + 12(0.83) = 30
20.24 + 9.96 = 30.16
Assuming minor rounding issues this looks accurate.
Answer:
Triangle ADE is congruent to triangle CBE because if you were to rotate one of the triangles 180° then it would line up perfectly.
