Answer:
Option B) (-1,7,5) is correct.
The solution to the given system of equation is (-1,7,5)
Step-by-step explanation:
Given system of equations are
To find the solution of the given system of equations by using Elimination method:
Now adding equations (1) and (2)
_________________
________________
(since "-" getting cancelled)
Now adding equations (1) and (3)
_________________
________________
Now adding equations (4) and (5)
_________________
________________
Therefore y=7
Substituting y=7 in equation (4)
Therefore x=-1
Now substituting the values x=-1 and y=7 in equation (1) we get
Therefore z=5
Therefore the solution to the given system of equation is (-1,7,5)
Therefore Option B) (-1,7,5) is correct.
Tom started with 20 newspapers on the morning and returned with 8 newspaper.
<h3>Equation</h3>
Equation is an expression used to show the relationship between two or more variables and numbers
Let x represent the amount of newspaper Tom started with.
He Delivered 10 newspapers on Flinders Street, hence:
He Delivered 6 newspapers on Collins Street, hence:
He Picked up 20 newspapers from the newsagent and Delivered 15 newspapers on Lonsdale Street, hence:
- = x - 16 + 20 - 15 = x - 11
He returned home there were eight newspapers in his bag. Hence:
x - 11 = 8
x = 20
Tom started with 20 newspapers on the morning and returned with 8 newspaper.

Answer:
Step-by-step explanation:
Each block has two 20×1 faces, two 20×2 faces, and two 2×1 faces.
Surface area of one block = 2(20×1) + 2(20×2) + 2(2×1) = 124 sq in
Total surface area = 4(124) = 496 sq in.
Largest surface area: Assemble the blocks end-to-end into a block that is 80 by 2 by 1. Six of the 2 by 1 faces are hidden, so the surface area is 496 - 6(2×1) = 484 sq in.
Smallest surface area: Assemble the blocks into a block that is 20 by 4 by 2. Four of the 20 by 2 faces and four of the 20 by 1 faces are hidden, so the surface area is 496 - 4(20×2) - 4(20×1) = 256 sq in.
Difference in surface area = 484-256 = 228 sq in.
