4 1/5 + b = 9 3/5
4 1/5 - 4 1/5 + b = 9 3/5 - 4 1/5
(taking the same amount from each side to keep it balanced)
0 + b = 5 2/5
(subtracting 4 1/5 from each side)
b = 5 2/5
P=25r-12500
p=125000 and r=?
125000=25r-12500
+12500 +12500
25r= 137500
r=137500/25
r= 5,500
Therefore the answer is B) 5,500
Answer: 
Step-by-step explanation:
Given:
To make 
the subject of the formula means that we want to make to stand alone , the first thing to do is to multiply through by 1/4a , that is
take the square of both sides:
Answer:
Step-by-step explanation:
The given expression is
Factor the first two and the last two.
Apply difference of two squares to the leftmost factor.
Dist. travelled for the first 2 days
= 22 + 28
= 50
Dist. travelled for the remaining 83 days
= 1378 - 50
= 1328
Dist. travelled for EACH of the 83 days
= 1328 ÷ 83
= 16
