Answer:

Step-by-step explanation:

Attached is a copy of the figure with some of the clutter removed. The congruent angles marked with a single arc, and the parallel lines are given.

The angles marked with a double arc are congruent because they are alternate interior angles where transversal XZ crosses parallel lines XW and YZ. Of course, side XZ is congruent to itself.

Hence we have two angles and a side not between them that are congruent. We can declare ∆XWZ ≅ ∆ZYX by the AAS postulate. (choice A)

Natalie baked 20 cupcakes for a fundraising event at school. On the way to the event she dropped 35% of the cupcakes on the floo

FinnZ [79.3K]

Answer:

The total number of cupcakes that Natalie dropped is 7.

Step-by-step explanation:

This question can be solved using a rule of three.

The amount of cupcakes that she has, which is 20, is 100% = 1. How many cupcakes is 35% = 0.35?

20 cupcakes - 1

x cupcakes - 0.35

x = 20*0.35 = 7

The total number of cupcakes that Natalie dropped is 7.

G(n-7) if g(x) =x^2-5/3x

Leno4ka [110]

Instead of x, we write n - 7 in the function equation

$g(x)=x^2-\dfrac{5}{3}x\\\\g(n-7)=(n-7)^2-\dfrac{5}{3}(n-7)\\\\\text{use} (a-b)^2=a^2-2ab+b^2\\\text{and distributive property}\\\\=n^2-2(n)(7)+7^2+\left(-\dfrac{5}{3}\right)(n)+\left(-\dfrac{5}{3}\right)(-7)\\\\=n^2-14n+49-\dfrac{5}{3}n+\dfrac{35}{3}\\\\\text{combine like terms}\\\\=n^2+\left(-14n-1\dfrac{2}{3}n\right)+\left(49+11\dfrac{2}{3}\right)\\\\=n^2-15\dfrac{2}{3}n+60\dfrac{2}{3}$
