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? a. 3 + 4 + 5 b. (1−z) c. (1−x) d. 4(1−y)

I’m pretty sure it’s A.

3 would represent the price of the cheese, 4 would represent the price of the loaf of bread and 5 would represent the ham

Hope this helps

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
