Answer 1

Answer:

1. D

2. A

3. C

Step-by-step explanation:

1. Given

$6-\dfrac{1}{2}z=\dfrac{2}{3}$

Multiply the equation by 6:

$6\cdot 6-6\cdot \dfrac{1}{2}z=6\cdot\dfrac{2}{3}\\ \\36-3z=4$

Hence,

$-3z=4-36\\ \\-3z=-32\\ \\3z=32\\ \\x=\dfrac{32}{3}$

2. Given

$\dfrac{3y}{2}+\dfrac{ky}{4}=6$

Multiply the equation by 4:

$\dfrac{3y}{2}\cdot 4+\dfrac{ky}{4}\cdot 4=6\cdot 4\\ \\6y+ky=24$

Use distributive property:

$y(6+k)=24\\ \\y=\dfrac{24}{6+k}$

3. Given

$3-(w+2)>4+2w$

Open the brackets using distributive property:

$3-w-2>4+2w\\ \\1-w>4+2w$

Hence,

$1-w>4+2w$
