Let x be the age of Ben and y be the age of Ishaan.
x= 4y... Equation (1)
x= y + 6... Equation (2)
Subtract the 2 equations
(1) - (2) : x-x= 4y - (y+ 6)
0 = 4y - y - 6
0 = 3y - 6
3y = 6
y = 2
So Ishaan is 2 years old
Substitute y = 2 in equation (1)
x = 4(2)
x = 8
So Ben is 8 years old and Ishaan is 2 years old.
Write 2/625 and then multiply the result by 100%: 200%/625 can be re-written as 8% / 25 by dividing both 200 and 625 by 25.
8% / 25 can be thought of as "eight twenty-fifths of 1 percent. (ANSWER)
Using my calculator, I found that 2/625 is 0.0032. Mult. that by 100% results in 0.32. Note that 8/25 = 0.32.
The answer to this proportion would be X=4
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.
- 1/2, because -1/2 + 1/2 = 0
