Question

ollie is making salad dressing.He mixes 1 part vinegar to 2 parts oil.Ollie makes 450mls of salad dressing.how much oul does he use​

Answer 1

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

Answer 2

The amount of oil used by Ollie is 300ml.

What is linear equation in one variable?

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.
