Use distributive property: multiply the number outside the bracket by each number inside it
1. 14x+21=35 14x=14 x=1
2. -32x-24=40 -32x=64 x= -2
3. 16-10x=-44 -10x=-60 x=6
Answer:
Height of the building = 50.8 ft
Step-by-step explanation:
A person and a building are casting the shadows at the same time of the day.
Triangles formed by the person and his shadow and the building and its shadow will be similar.
Therefore, corresponding sides of the similar triangles will be proportional.
x = 
x = 50.75
x ≈ 50.8 ft
To approximate the number of chairs that can be set up in floor space, we just have to divide the total floor area by the area that each chair needs. That is,
n = (40 ft x 32 ft) / (4 ft x 5 ft)
n = 64
Therefore, there are 64 chairs that can be set up in the floor.

Answer:
A and E
Step-by-step explanation:
Given
Graphs A to E
Required
Which do not have solutions
When there are no point of intersection between lines and/or curves of a graph, then such graph has no solution.
Using the above description as a yard stick, the first (A) and the last (E) graph have no solution.
