Solving for a gives us: 
Step-by-step explanation:
Solving an equation for a variable means that we have to isolate the variable in the equation
Given equation is:

For isolating a, subtracting c from both sides

Subtracting b from both sides

Hence,
Solving for a gives us:

14 kg because 2/5 equals 0.4 and 0.1 equals about 1 kg so I add 0.6 which equals 6 kg so i add 8 kg to 6 kg and get 14 kg
900 × 126= 116,100. Hoped this helped.
The perpendicular bisector of the segment passes through the midpoint of this segment. Thus, we will initially find the midpoint P:

Now, we will calculate the slope of the segment support line (r). After this, we will use the fact that the perpendicular bisector (p) is perpendicular to r:


We can calculate the equation of
p by using its slope and its point P:
Answer:
c. The solution to a system of equations is the point or points where they intersect
