180-47=133 bc straight angles measure 180
18+15y-10
=18-10+15y
=8+15y
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
