Answer:
Option D is correct.
Value of z =5
Step-by-step explanation:
Given the equation: ![2(3z-2)+8=34](https://tex.z-dn.net/?f=2%283z-2%29%2B8%3D34)
Using distributive property: ![a\cdot (b+c) = a\cdot b+ a\cdot c](https://tex.z-dn.net/?f=a%5Ccdot%20%28b%2Bc%29%20%3D%20a%5Ccdot%20b%2B%20a%5Ccdot%20c)
Apply distributive property in the given equation we have;
![6z - 4 + 8 = 34](https://tex.z-dn.net/?f=6z%20-%204%20%2B%208%20%3D%2034)
⇒![6z +4 =34](https://tex.z-dn.net/?f=6z%20%2B4%20%3D34)
Subtract 4 from both sides we get;
6z + 4 -4 = 34-4
Simplify:
6z = 30
Divide by 6 to both sides of an equation, we get;
z = 5
Therefore, the value of z is, 5
Answer:
137.5 lbs.
Step-by-step explanation:
Arthur = 54 + x
Lily = x
Arthur + Lily = 6x - 280
(54 + x) + x = 6x - 280
54 + x + x = 6x - 280
54 + 2x = 6x - 280
54 = 4x - 280
334 = 4x
83.5 = x
Arthur = 54 + x
Arthur = 54 + 83.5
Arthur = 137.5
45.967 rounded to the nearest 10th is 46
3(3/5) = n
