Does 2/3x+3/4=8 and 8x=87 have the same solution ?

Answers

(2/3)x + (3/4) = 8
           -(3/4)   -(3/4)

(2/3)x = 7.25(3/2)
(3/2)

x = 10.875

8x = 87 Divide both sides by 8

x = 10.875

So yes both sides have the same solution 

Hope this helps :)

Which sentence fully illustrates that polygon ABCD is congruent to polygon PQRS?

Answers

Ans: Polygon ABCD maps to polygon PQRS through a reflection only.

Explanation:
As you can see in the figure that the polygon PQRS is the reflection of the polygon ABCD. If we reflect the polygon ABCD on the x-axis, we would get the polygon PQRS. Congruency means that both shapes have the same measure, which in this case, both these shapes have the same measure. Therefore, we can say that polygon ABCD maps to polygon PQRS through a reflection only in order to be congruent to each other.

Answer:

polygon ABCD maps to polygon PQRS through a reflection only.

From 12 prepared songs, a bandchooses 3 to perform on a TV show. One
song will be played at the beginning of
the show, one in the middle, and one at
the end. Tell how many different set lists
are possible. Then tell if the situation
involves permutations or combinations.

Answers

Answer:

1320 different set lists are possible

Step-by-step explanation:

We have a set of 12 elements (12 songs)

There can be NO songs repeatedly

The order of the songs is important because One song will be played at the beginning of the show, one in the middle, and one at the end.

So as the order of selection is important we must use permutations.

The formula for permutations is:

nPr=(n!)/((n-r)!)

where n is the number of items you can choose and choose r from them

In this case we know that:

n=12, r=3

Then:

12P3=(12!)/((12-3)!)

12P3=(12!)/(9!)

12P3=1320
