6 (3+10)
15 + 33
-30/1
The expression ( 18^{\frac{1}{2}} ) represents the square root of 18. Therefore, the equivalent radical expression is ( \sqrt{18} ), which can also be simplified to ( 3\sqrt{2} ) since ( 18 = 9 \times 2 ).
No. It is equivalent to 18/20 or 27/30.
30 -5 =x
18:30 = 3:5
To determine if the expressions (-12x - 18) and (-6x - 9 - 3(3 - 2x)) are equivalent, we can simplify the second expression. Distributing the (-3) gives (-6x - 9 - 9 + 6x), which simplifies to (-18). Thus, the expression simplifies to (-18), while the first expression is (-12x - 18). Since the two expressions are not the same (the first has a variable term), they are not equivalent.
To simplify the expression ( 6(x + 3) - 5x ), first distribute the 6: ( 6x + 18 - 5x ). Combining like terms gives ( (6x - 5x) + 18 = x + 18 ). Therefore, the expression is equivalent to ( x + 18 ). Any choices that simplify to ( x + 18 ) would be equivalent.
18(2 + 3)
0.6
They are not equivalent.
To find the score of 18 out of 30 as a percentage, divide 18 by 30 and then multiply by 100. This calculation gives you 60%. Therefore, 18 out of 30 is equivalent to a score of 60%.
