Evaluate the expression to find the total number of muffins and bagels joan sells in 5 days

Total  no. of muffins and bagels sold in 5 days = 5x + 5y

Step-by-step explanation:

Let the no. of muffins sold in a day = x

The no. of muffins sold in 5 days  = 5*x = 5x

Let the no. of bagels sold in a day = y

The no. of bagels sold in 5 days      = 5 * y = 5y

Total  no. of muffins and bagels sold in 5 days = 5x + 5y

x=30

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
