145% of what number is 870 is 870/1.45=600
Answer=600
<em>Exterior angle of the triangle is equal to the sum of the opposite angles.</em>
9x = 5x + 9 + x
<em>Combine like terms:</em>
9x = 6x + 9
<em>Take away 6x from both sides:</em>
3x = 9
<em>Divide by 3 on both sides:</em>
x = 3
Answer: x = 3
Answer:
2nd option because the number next to the x is the slope (3) and the added number is your intercept (4)

Answer:
The height of the tower = 24 units.
Explanation:
In the question above, we are given the following variables.
The total number of blocks used = 312 blocks
The bottom layer( base of the tower) = 13 blocks
We are to find how tall the tower is = height of the tower = unknown.
The total number of blocks used = Volume of the tower = 312 cubic units(blocks)
Area of the base = number of the blocks used in the bottoms layer = 13 square units( block).
Because blocks are used, we assume that this is a Rectangular based prism
The Volume of a Rectangular based prism = Area of the base × h
312 = 13 × h
h = 312 cubic units ÷ 13 square units.
h = 24 units.
There fore, the height of the tower = 24 units
