When you simpilfy a fraction you make it smaller. When you divide a number you make it smaller.
Ex: 5 /5 1
_ = _
10 /5 2
by triangle angle addition law
a + b + c = 180
3x +1 + 2x-1 +40 = 180
5x +40 = 180
5x = 180 - 40 = 140
x = 140/5 = 28
so
b = 2x -1 = 2×28-1= 56-1 = 55
A^2 + 3^2 = 5^2
a^2 + 9 = 25
a^2 = 16
a^2 = (square root)16
a = 4
Answer:
The expression 35 - m is used to determine the number of gallons left in the tank after m minutes.Solution:Given that a tank containing 35 gallons of water is leaking at a rate of gallon per minute. Let "m" represent the number of minutes spent Number of gallons left in the tank = initial amount of water present – leaked amount of water
Number of gallons of water left = 35 gallons – number of minutes spent rate of leakage.
Number of gallons of water left = 35 gallons – m minutes 1 gallons per minute Hence, the required expression is 35 – m
