Really need this jovan needs to buy a package of ham for $5, a package of cheese for $3, and a loaf of bread for $4 to make lunch. jovan has a coupon that gives him x percent off on a package of cheese. he has a second coupon that gives him y percent off on a loaf of bread. he has a third coupon that gives him z percent off on his total purchase. jovan cannot combine the coupon for the total purchase with the other two coupons. these expressions give both possibilities for the total cost of jovan's purchase after the coupons are applied. the variables represent percentages as decimals. (1−x)3+(1−y)4+5 (1−z)(3+4+5) which part of the expression represents the price of the ham, the cheese, and the bread before the total discount is applied? answer choice: 3+4+5: : (1-x): : 4(1--y): : (1 - z)

∠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.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
