Let h equal the length of the party in hours

200.66 + 30.53h = 322.78

now just solve for h :)
30.53h = 122.12
h = 4

so the party was 4 hours long

4 hours because you have to first subtract 322.78 and 200.66 then whatever you get you divide that by 30.53

segment R prime S prime = three segment RS

Step-by-step explanation:

we know that

A dilation is a non rigid transformation, that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

The scale factor is 3

Applying proportion

therefore

segment R prime S prime = three segment RS
