Which expressions are equivalent to z ⋅ 3 1/3 select all that apply

3z+1/3
6z−2/3z−3z+z
z ⋅ 4−2/3
z(4−2/3)
z(1/3+3)

Options 2), 4 , and 5 are CORRECT

Step-by-step explanation:

Notice that z * 3  1/3 = z * (3 + 1/3) = z * (9/3 + 1/3) = z * 10/3 = 10/3 z

1)  The first option is not good'

2) 6 z - 2/3 z - 3 z + z = 4 z - 2/3 z = 12/3 z - 2/3 z = 10/3  z  So this option is CORRECT

3) z * 4 - 2/3 is not good since 2/3 is not multiplied by z

4) z ( 4 - 2/3) = z (12/3 - 2/3) = z * 10/3  so this one is CORRECT

5)  z (1 / 3 + 3) = z ( 1/3 + 9/3 ) = z (10/3)  So this one is also CORRECT

y + 11 = (1/4)(x + 16)

step-by-step explanation:

i would be happy to . most people on would also love to i'm sure. if you just want someone who has done algebra before and want a little more personal relationship than just begging strangers for , i can certainly be of service. i do have college myself so i might not be 24/7.
