Noah planned a parallelogram-shaped sidewalk to lead from the street to the front door of his house. He realized the walkway was
too short and he needs to change the length to 72 feet. He wrote a ratio to find the change in the scale factor. 24 ft 72 ft = The change in the scale factor is . The change of scale means that 1 inch represented feet, but now 1 inch represents feet.

Hey there!
Let's write this as a ratio/proportion.
The sum of this basic ratio is 4.25.
To figure out how much of each we have for 34, we divide this 34 by 4.25, our sum of the two ingredients. This will give us a factor we can multiply our two ingredient measurements by.
34/4.25=8
Now, we multiply our two ingredients by eight.
2.75(8)=22
1.5(8)=12
Note that these two add up to make 34 tablespoons.
Therefore, we have...
22 tablespoons of olive oil and 12 tablespoons of balsamic vinegar were used in the 34 tablespoons of bread dip.
I hope this helps! Have a great day! :)
