A recipe used 2/3 of sugar for every 2 teaspoons of vanilla.how much sugar was used per teaspoon of vanilla.
mrs_skeptik [129]
Hi there,

The answer is 1/3 cup per teaspoon. Here’s how...


All you have to do is divided 2/3 by 2.

We have to put a 1 under the 2 to at least represent it as a fraction.

2/3 / 2/1

Next we flip 2/1 into 1/2.

2/3 / 1/2

Now we are going to multiply.

2x1=2

3x2=6

We get 2/6, simplifying that we get 1/3 cup per teaspoon.

Can some help thanks
AleksAgata [21]

The answer would be 30 because the two given angles are proportionate to each other so if you find the side on the triangle with both lengths given you will see there is a scale factor of 5 so the corresponding segment on the other triangle is 6. Multiply by 5 then you will have 30 for x.

The number of question on an exam varies with the number
alekssr [168]

Answer:

t=5x

Step-by-step explanation:

So the number of questions in an exam varies with the number of minutes to take the exam.

For each question there are 5 minutes allotted.

Lets say that there are 'x' number of questions in the exam and 't' is the total time taken to finish the exam, in minutes. So the time taken to complete the exam would be

5 \times x=5x

Therefore, the equation relating the time taken to complete the exam and the number of questions is given by:

t=5x

So there are two variables in the equation, 't', and 'x':

t - time taken to complete the exam

x - number of questions on the exam
