I dont know sorry,hope you find someone that helps tho!!
I took the quiz the answer is A,B,D,E
Hope I Helped!
<span>Step 1: Simplify both sides of the equation.
</span>1/2 (6−z) = <span>z
</span><span>
(1/2) (6) + (1/2) (-z) = z (distribute)
3 + -1/2z = z
-1/2z + 3 = z
</span><span>Step 2: Subtract z from both sides.
</span><span>
-1/2z + 3 - z = z - z
-3/2z + 3 = 0
</span><span>Step 3: Subtract 3 from both sides.
</span><span>
-3/2z + 3 - 3 = 0 - 3
-3/2z = -3
</span><span>Step 4: Multiply both sides by 2/(-3).
</span><span>
(2/-3) * (-3/2z) = (2/-3) * (-3)
z = 2
Answer: z = 2
I hope this helps you!:) Sorry it took me so long!

Answer:
2.99x + 12.99y = 43.92
Step-by-step explanation:
socks cost 2.99 and she bought x
2.99x
blouses cost 12.99 and she bought y
12.99y
The total is
2.99x + 12.99y
The total cost was 43.92
2.99x + 12.99y = 43.92
Answer:
(- 2, - 4 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 2 → (1)
5x - 5y = 10 → (2)
Multiply (1) by 5 and (2) by - 3, then add to eliminate x
15x - 10y = 10 → (3)
- 15x + 15y = - 30 → (4)
Add (3) and (4) term by term to eliminate x , that is
5y = - 20 ( divide both sides by 5 )
y = - 4
Substitute y = - 4 into either of the 2 equations and solve for x
Substituting into (1)
3x - 2(- 4) = 2
3x + 8 = 2 ( subtract 8 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
Solution is (- 2, - 4 )
