Lily received $55 for her birthday. She used some of the money to buy 4 pencils priced at m dollars each. Write an expression to show how much money Lily would have left.

55 - 4m = x

Step-by-step explanation:

This expression shows how much money Lily has left.

This is because, if Lily received $55 for her birthday, and she used some of her money to buy 4 pencils that cost m each, 5 minus 4 multiplied by the amount of money each one costed equals the amount that she has left.

Therefore, the correct expression is 55 - 4m = x.

Hope this helps! :D

i would say c is the best answer, hope it's right!

good luck! =)

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.
