Answer:
c
Step-by-step explanation:
1 rod or long is a column of 10 unit cubes.
10 longs placed side by side, form a flat (with dimensions 10×10)
10 flats, placed on top of each other form a large cube, with dimensions 10×10×10 = 1000 cubes.
-------------------------------------------------------------------------------------------------
each small cube (unit cube) represents the number 1.
thus each long represents 10
each flat represents 100
and each large cube represents 1,000
The number 13,450 can be written as
1*10,000+3*1000+4*100+5*10 using the expanded form.
This means that there are 13 large cubes, 4 flats and 5 longs needed to model the number.
Answer: 13 large cubes, 4 flats, 5 longs
9514 1404 393
Answer:
no solution (parallel lines)
Step-by-step explanation:
You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...
The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
So what you will need to do is subtract 2x - 3x = -x, then subtract three from both sides 8 - 3 and the answer will be -x + 5
