(40 - x) represents A. the number of undamaged cards

Step-by-step explanation:

Step 1; Maria has a total of 40 cards out of which x number of cards are damaged so 40 - x cards are undamaged. The value of an undamaged card is 5 dollars whereas every damaged card has a value of 3 dollars.

Step 2; We need to determine what each term in equation 5(40−x)+3x represents. The equation will give us how much total value Maria's card collection has.

The first term 5 (40 - x) signifies the total value of the undamaged cards in the deck where (40 - x) equals the total number of undamaged cards.

The second term represents the total value of the undamaged cards.

So the second factor of the first term i.e (40 - x) represents the amount of undamaged cards in her collection.

What is the length of AB
Anettt [7]

Answer:

\boxed{\boxed{\overline{AB}=16}}

Step-by-step explanation:

In the triangle ABC, m∠ABC=90°. Hence, it is right angle triangle.

\tan \theta=\dfrac{p}{b}=\dfrac{AB}{64}  --------1

In the triangle ABD, m∠ABD=90°. Hence, it is right angle triangle.

\cot (90-\theta)=\dfrac{b}{p}=\dfrac{4}{AB}

As \cot (90-\theta)=\tan \theta, so

\tan \theta=\dfrac{b}{p}=\dfrac{4}{AB}  ---------2

From equation 1 and 2,

\Rightarrow \dfrac{AB}{64}=\dfrac{4}{AB}

\Rightarrow AB^2=64\times 4

\Rightarrow AB^2=256

\Rightarrow AB=\sqrt{256}

\Rightarrow AB=16

1) Simplify the following:
aivan3 [116]

Step-by-step explanation:

ok so for number 1 you first have to group the like terms therefore you will now have:

9r-4r+8-6

and now you calculate:

9r-4r=5r

8-6=2

so that means 5r-2 is simplied version for no.1

for number you 2 you first multiply why is inside the brackets by what is in the outside:

2(x+3y)

2x+6y (simplified version)

hope this helps! no problem
