Step-by-step explanation:
The area of a triangle is base * height / 2, or in the case of a right triangle (like this), the legs multiplied by each oehter then halved is the area.
(10 * 10.5) / 2 = 52.5

Answer:
18
Step-by-step explanation:
The answer is 18.
As half of 36 is 18
The first thing we must do for this case is to define a variable:
x: number of years
y: total salary
We have then:
For first company:
y = 1500x + 31000
For second company:
y = 2000x + 28500
Equaling both equations we have:
1500x + 31000 = 2000x + 28500
Clearing x:
2000x - 1500x = 31000 - 28500
500x = 2500
x = 2500/500
x = 5
Answer:
It will take for the salaries to be the same about:
x = 5 years
The equation y=4x is already in y=mx+b format.
m=4
b=0
so you can write as:
y=4x+0
