Two numbers x and y are such that: a) The sum of 3 times x and 5 times y is 57 b) y is 1 more than twice the value of x What is the value of x + y?​

0.02040816326

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

answer4 to the second power is 16

and 4 to the third power is 64,

they go with it happens or they mite give a chance?
