which of the pairs of expressions are equivalent
(k * 18) * 0.5 and k * (18 * 0.5)
(y - 9) - 8 and y - ( 9 -8)
(d devided by 8) devide by 4 and d divide by (8 devided by 4)
x * (5 plus 2) and (x * 5) plus 2
The pairs of expressions that are equivalent are:
1. (k * 18) * 0.5 and k * (18 * 0.5)
Both expressions would give the same result when simplified.
2. (y - 9) - 8 and y - (9 - 8)
Both expressions would give the same result when simplified.
3. (d divided by 8) divided by 4 and d divide by (8 divided by 4)
Both expressions would give the same result when simplified.
The expressions "x * (5 plus 2)" and "(x * 5) plus 2" are not equivalent.
