If you would like to know in which step did the student first make an error and what is the correct step, you can calculate this using the following steps:
3(2x - 4) = 8 + 2x + 6
6x - 12 = 8 + 2x + 6
6x - 12 = 14 + 2x ... Step 2
6x - 2x = 14 + 12
4x = 26
x = 26/4 = 13/2
The correct result would be Step 2; <span>6x - 12 = 14 + 2x.</span>
An empty cubical carton of side 7cm has the volume:
7 x 7 x 7 = 343cm³
A cube of side 1cm has the volume:
1 x 1 x 1 = 1cm³
From this, we can see that a 1000 cubes of side 1cm has the volume:
1000 x 1cm³ = 1000cm³
But we know that the cubical carton of side 7cm only has a volume of 343cm³.
Since 1000cm³ > 343cm³,
you cant fill 1000 cubes of side 1cm in such a carton.
TL;DR
No

Answer:
y = 38
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Consider the angles in the large outer triangle, then
x + 46 + 78 = 180
x + 124 = 180 ( subtract 124 from both sides )
x = 56
Consider the 3 angles in the smaller inner triangle, then
y + x + 86 = 180 , that is
y + 56 + 86 = 180
y + 142 = 180 ( subtract 142 from both sides )
y = 38
