It is an easier and faster way to write an equation for the slope of a line if you already have its points and slope.
487 + 310 ≈ 500 + 300 ≈ 800
Let
x-------> Leila 's profit
y------> Jo's profit
we know that
----------> equation 
For 
<u>Find the value of x</u>
Substitute the value of y in the equation 



therefore
<u>the answer is</u>
Leila make
in profit
Answer:
4% of 175,000 is 7,000
7,000x 5=35,000
175,000-42,000 equals 140,000 the value of the house
Answer:
Force= Mass×Accelaraion
F=m×a
But as The unit of accelaration is given miles per hour and the SI is meters per second sqaure we have to convert 10mph to m/s²
Thus, we have 10mph = 4.47 meters per second square. (i converted using scientific calculator)
So now we have,
2000N= m×4.47m/s²
= 2000/4.47m/s²=m
= 447.42
Thus the mass of the object is 447.42 (i am not sure of units)
