Answer:
x = 48/7
Step-by-step explanation:
There's two good ways to do this problem.
Option 1:
Translate "x varies directly as y" into the equation y=kx
Then you have to find k. After you "reset" your y=kx equation, fill in k and then solve for x. See image.
Option 2:
Translate "varies directly" into a proportion, which is two fractions equal to each other:
x/y = x/y
Fill in the three numbers given and cross multiply and solve to find the fourth number. See image.
Answer:
4/5 ÷3/5
4/5×5/3(any time one is dividing a fraction, the dominator would go up while the numerator would come down).
=4/3
The statement 'of ' represents multiplication.
thus, baby = 1/40 * 120 = 3 tons.
1 ton is 2000 pounds.
Hence, 3 is 6000 pounds.
