Answer:
x = 2y
x - 8 = y + 6
replace x by 2y in the second equation
2y - 8 = y + 6
y - 8 = 6
y = 14
x = 2*14 = 28
Kendra had $28 and Kareem had $14.
Flour: 2 3/4 cups = 11/4
11/4 * 2 = 22/4 = 5 2/4 cups
Sugar: 1 1/2 cups = 3/2
3/2 = 6/4 = 1 2/4 cups
1 2/4 * 2 = 3 cups
So it *should* be 8 1/2 cups.

Answer:
[5 . (3 . 12)] shows an equivalent expression to [(5 . 3) . 12] if only the associative property was used to transform the expression ⇒ 1st answer
Step-by-step explanation:
The associative property means you can add or multiply some numbers without matter where you put the parenthesis
Ex: (a + b) + c = a + (b + c) <em>OR</em> (a . b) . c = a . (b . c)
<em>In associative property we move the parenthesis only (we do not move the numbers)</em>
Subtraction or division are not associative
∵ The expression is [(5 . 3) . 12]
- The parenthesis are around the first two numbers, then the
equivalent expression is the one whose parenthesis are
around the last two numbers
∴ The equivalent expression is [5 . (3 . 12)]
∴ [(5 . 3) . 12] ≡ [5 . (3 . 12)]
[5 . (3 . 12)] shows an equivalent expression to [(5 . 3) . 12] if only the associative property was used to transform the expression
