Answer:
3500 tons
Step-by-step explanation:
The Greenpoint factory produced 2/5 of the bricks that the Consolidate Brick Company produced in 1991.
Let the amount of bricks produced by the Greenpoint factory be g and the amount of bricks produced by the Consolidated brick company be c.
Therefore:
g = 2/5 * c = 2c/5
That year, the Greenpoint factory produced 1400 tons of bricks. This implies that:
1400 = 2c/5
To find the amount that the Consolidated Brick Company produced, solve for c:
1400 = 2c/5
1400 * 5 = 2c
7000 = 2c
c = 7000 / 2 = 3500 tons
The Consolidated Brick Company had a total production output of 3500 tons in 1991.
 
        
             
        
        
        
Answer:
1 pear = $0.75; 1 orange = $0.65
Step-by-step explanation:
(1)               3P +  4O = 4.85
(2)              3P + 10O = 8.75                 Eqn (2) - Eqn (1)
3P + 10O – 3P – 4O = 8.75 – 4.85     Combine like terms
                            6O = 3.90                 Divide each side by 6
                              O = $0.65              Substitute into Eqn (1)
            3P + 4×0.65 = 4.85
                3P + 2.60 = 4.85                 Subtract 2.60 from each side
                            3P = 2.25                Divide each side by 3
                             P = $0.75
Oranges cost $0.65 each and pears are $0.75 each
