Answer:
A linear equation can be written in several forms. "Standard Form" is #ax+by=c# where #a#, #b# and #c# are constants (numbers).
We want to make two equations that
(i) have this form,
(ii) do not have all the same solutions (the equations are not equivalent), and
(iii) #(4, -3)# is a solution to both.
#ax+by=c#. We want #a#, #b# and #c# so that
#a(4)+b(-3)=c# (This will make (i) and (iii) true.)

Answer:
It helps distinguish it from other means, such as the geometric mean and the harmonic mean. When someone asks for the average of a group of numbers, they’re most likely asking for the arithmetic mean. An arithmetic mean is calculated by adding several quantities together and dividing the sum by the number of quantities.

Rachel's speed is 38 m/s.
Equations are mathematical statements with twoalgebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
D = -38t + 220
So, t = 1
D = -38t + 220
D = -38(1) + 220
D = -38+ 200
D = 182 m
So, v = / t
v = ( 220- 182) /1
v = 38 m/s
Hence, Rachel's speed is 38 m/s.
