Answer: A
Step-by-step explanation:
Focus on what it is saying. It is saying that 5x IS LESS THAN OR EQUAL TO 15.
So we are looking for smaller numbers, that is, values of x, in order to make this statement true.
So on a number line we are looking for the left part shaded in.
Furthermore... notice that the sign has "or equal to". Thus the circle is going to be shaded in. The circle is not going to be open and empty. Through this we have eliminated answers B and C.
So the answer is A because— remember— the left side of the number line is shaded. It encompasses negative numbers. A negative number times 5 will definitely be less than 15.
Answer: 3
Step-by-step explanation:
Given
The dimension of the small block is

The Volume of the cube having unit length is

The number of blocks that can be in the unit cube is the division of the volume of the unit cube and block.

Plus 10 from both sides
5=-5x
X = -1
