Answer:
Yes and she would have $2 left over because all the food costs $91.
Step-by-step explanation:
We should set up an equation so that everything makes sense. A calculator would be wise for this problem, but I am going to lay it out anyhow.
We should convert the mixed numbers to improper fractions to not be confused. 3 1/2 becomes 7/2 or 3.5 and 2 1/3 becomes 7/3.
From your wording, we can assume that the money Mrs. Donnelly has is either greater than or equal to $93.
Thus, we have 12*(7/3) + 18*(7/3) is equal to or greater than 93 (this is an inequality).
The math shows that the food costed 91 and so she only has $2 left.

Answer:
1) 6^2 + 8^2 = x^2
36 + 64 = x^2
100 = x^2
x = 10 feet
2) 15^2 + 8^2 = x^2
225 + 64 = x^2
x ^ 2 = 289

Answer:
36 parts water
Step-by-step explanation:
3/9 = 1/3 = for every 1 part concrete, it's 3 parts water.
12/x = 1/3; x = 36
so, 12 x 3 = 36
