Billy was folding laundry. She folded 40 shirts from 7:20 to 7:40. When she finishes folding all the shirts, she was done. (a) If she started folding shirts at 7:15 and ended at 7:39, estimate how many shirts she would have folded in all. Explain your reasoning.

(b) Write an equation to represent how many shirts Billy has left to fold if she started at 7:15. Explain your reasoning.

(This isn't a question you can pick A or B, you have to answer both)

Examine the paragraph proof. which theorem does it offer proof for? prove jnm – nmi according to the given information in the image. jk | hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality alternate interior angles theorem gorresponding angle theorem vertical angle theorem o same side interior angles theorem
