Answer:
let one part =x
part of vinegar= x
part of oil =2x
part of oil +part of vinegar = 450ml
2x+x=450
3x=450
x=450/3
x=150
part of vinegar=150ml
part of oil= 300ml
The amount of oil used by Ollie is 300ml.
The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.
Suppose the vinegar is x ml.
So, the oil is 2x ml.
Ollie makes 450mls of salad dressing.
⇒ 2x + x = 450
Solve the above linear equation for x.
⇒ 3x = 450
⇒ x = 150ml
Therefore, amount of oil she used = 2 × 150ml = 300ml.
Hence, the amount of oil used by Ollie is 300ml.
