Answer: -5z + 5

Step-by-step explanation:

23 + 2z ✖️2 - 9z -18

multiply the numbers: 2✖️2=4

= 23 + 4z -9z - 18

add similar elements: 4z - 9z = -5z

= 23 - 5z - 18

group like terms

= -5z + 5

Add/subtract the numbers: 23 - 18 = 5

= -5z + 5

hope this helps ;w;

x^2 - 0.25x - 0.75 = 0
</span><span>x^2 - 0.25x = 0.75
</span>x^2 - 1/4 x + 1/64 =3/4 + 1/64
(x-1/8)^2 = 49/64

16 divided by 1/8 minus 1
elena-s [515]
16 divided by 1/8 - 1

first, you would make 16 into a fraction, making the new equation 16/1 divided by 1/8 -1. you'd then flip 1/8 to 8/1 making the new equation 16 divided by 8 - 1. 16 divided by 8 is 2, and 2 - 1 = 1.

the answer is 1.
