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.

Pythagorean's Theorem 
A and b are both side lengths, c is the hypotenuse.
7^2 + 5^2 = 74
sqrt(74) is the answer for 1.
30^2 - 5^2 = 875
Simplify the radical. sqrt(875) --> 5sqrt(35). The answer for three.
There's a rule in geometry that says a diagonal of a square is the same length as taking a side length times the square root of two. There's your answer for two.

Step-by-step explanation:
We will have to expand first then we simplify.
<u>Expand</u>
You will have to distribute the 2 over the x & 7 and the 3 over the x & 1 respectively.
<u />
<u />
<u>Simplify</u>
You will have to add 2x & 3x together and 14 & 3 together.

Answer:
wk. 1 : 104, wk. 2 : 109, wk.3 : 218
Step-by-step explanation:
x = 1st week, y = 2nd week, z = 3rd week
x + y + z = 431
y = x + 5.........y - 5 = x
z = 2y
(y - 5) + y + 2y = 431
4y - 5 = 431
4y = 431 + 5
4y = 436
y = 436/4
y = 109 <==== week 2
z = 2y
z = 2(109)
z = 218 <==== week 3
x = y - 5
x = 109 - 5
x = 104 <==== week 1
