Answer:

$820

Step-by-step explanation:

D= Diamond Ring

S= Silver Ring

2D + 4S = 1880

D + S = 880

D = 880 - S

4S + 2(880 - S) = 1880

4S + 1760 - 2S = 1880

2S + 1760 = 1880

2S =  120

S = 60

880 - 60 = 820.

ohaa [14]

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.
