Question

Simplify (8z - 10) ÷ (-2) + 5(z - 1).


z
z - 1
z - 2


I got b

Answer 1

i got z-1.5

Answer 2

÷ (-2) is like * (-1/2)
so (8z - 10) * (-1/2) + 5(z - 1) then use the order of operations PEMDAS
(-1/2)(8z) + (-1/2)(-10) + 5z + (5)(-1) then simplify
-4z + 5 + 5z - 5 then add/subtract like terms

Answer 3

so am i correct?

Answer 4

not quite :)
try adding like terms for -4z + 5 + 5z - 5

Answer 5

yeh so x-1

Answer 6

z*

Answer 7

-4z + 5z + 5 - 5
z ^0
so it would just be z

Answer 8

isnt -4 +5=1

Answer 9

-4z + 5z = z(-4 + 5) = (1)z = z
5 - 5 = 0
