Answer:
Step-by-step explanation:
5 + x - 12 = x- 7 (Add the 5 and -12 to simplify)
x - 7 = x - 7 (notice its the same on both sides of equal sign. Add 7 to both sides)
x = x
solution is all real numbers
Part B
5 - 4 - 12 = -4 - 7
-11 = -11
5 + 0 - 12 = 0 - 7
-7 = -7
5 + 5 - 12 = 5 - 7
-2 = -2

The area of the triangular base is: 19
square units
How to calculate the base area
The given parameters are:
Volume = 27.36 cubic units
Height = 2.88 unit
The volume of a triangular prism is:
V = 0.5 * B *h
Where B represents the base area.
So, we have:
27.36 = 0.5 * B * 2.88
27.36 B * 1.44 -
Solve for B
B = 19
Hence, the area of the triangular base is: 19 square units
The answer is 60 degrees as well
Answer:
7.75%
Step-by-step explanation:
7
%
7.75%
Let x be the number of miles EXCLUDING the first
Amount of money paid (excluding the first : $(0.1).x
Total money paid (INCLUDING the 1st mile):
0.90 + (0.1)x = $3.2
0.1.x = 3.2 -0.90
0.1.x = 2.3
x = 2.3/0.1 = 23 miles
Now we have to add the 1st mile, then the total of miles = 23+1 = 24 Miles
