At Phones-R-Us, Xavier is paid $15 for every cell phone plan his customers purchase. Write an equation to represent, d, the total Xavier is paid for selling c cell phone plans.

d = 15c

Step-by-step explanation:

Amount Xavier is paid per cell phone plan purchased = $15

d = Total amount Xavier is paid

c = number of cell phone plan he sells

The equation:

Total amount Xavier is paid = Amount Xavier is paid per cell phone plan purchased * number of cell phone plan he sells

d = 15 * c

d = 15c

For instance, If Xavier sell 4 cell phone plan

d = 15c

d = 15(4)

d = 60

Total amount Xavier is paid for selling 4 cell phone plans = $60

∠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.

1/800 is the right answer
