That would first be a conversion factor is a number used to change one set of units to another, by multiplying or dividing. when a conversion is necessasry
Additive indentity
n = 1
a variable is always a number itself remember 7+n
5+2 = 7
5.7t < 420 divide both sides by 5.7
5.7 5.7
t < 73.68
So F(6) means 6 on the x axis then look to see where the graph is on the Y axis,
in this case on x 6 y=4
Answer:
(p+e)/(r-n) = x
Step-by-step explanation:
p + nx=rx-e
Add e to each side
p +e+ nx=rx-e+e
p +e+ nx=rx
Subtract nx from each side
p +e+ nx - nx=rx-nx
p+e = rx -nx
Factor out x
p+e = x(r-n)
Divide each side by (r-n)
(p+e)/(r-n) = x(r-n)/(r-n)
(p+e)/(r-n) = x
