A mixture of nuts contains 1 cup of walnuts for every 3 cups of peanuts write a linear equation that represents the relationships between penuts, x, and walnuts, y,

y=3x

Step-by-step explanation:

A mixture of nuts contains 1 cup of walnuts for every 3 cups of peanuts.

Let the number of cups of peanuts=x

Let the number of cups of Walnuts=y

For every 1 cup of walnut, there are 3 cups of peanuts.

For every 2 cup of walnut, there are 3(2) cups of peanuts.

Therefore, For every x cup of walnut, there are 3x cups of peanuts.

The linear equation that represents the relationship between y and x is therefore given as:

y=3x

answer are

step-by-step explanation:

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
