1. (1/3)s + 7/9 = (4/3)s
  [4/3 - 1/3]s = 7/9
    s = 7/9
-------------------------
 
2.In 2010 world grain supply will be 1.8 trillion metric tons and the supply will be only  3/4 of world grain demand. What will world grain demand be in 2010? 
1.8 = (3/4)(world demand)
world demand = (4/3)1.8) = 2.4 trillion metric tons
----------------------
3. Water boils at 212 F 
a) Use the accompanying graph to determine the Celsius temperature at which water boils. 
Comment: I don&#39;t see your graph but I know the boiling temperature of water
is 100 degrees Celsius
-----------------------
b) Find the Farenheit temperature of hot tap water at 70 C by solving the equation
70=(5/9)(F-32)
F-32 = (9/5)70
F-32 = 9*14
F = 126+32 = 160 degrees
---------------------------
 
4. 9-2m/7=19
-2m/7 = 28
-2m = 196
 m = - 98
