Answer:

$138

Step-by-step explanation:

Let the money with Raymond be $y

Let the cost of 1 tshirt be $x

then cost of 8 tshirt = cost of 1 t-shirt*8 = 8x

Raymond wanted to buy 8 t-shirt but he was short of $8.10

It means that 8x is equal to money he had plus $8.10

thus,

y + 8.10 = 8x

y = 8x - 8.10

Next situation

cost of 5 t-shirt = 5x

. instead he bought 5 T-shirt and had $12.60 left,

it means cost of 5 T-shirt plus $12.60 = total money Raymond had

y = 5x + 12.60

comparing y in both the equation

y = 8x - 8.10 and y = 8x - 8.10

5x + 12.60 =  8x - 8.10

=> 8x-5x = 12.60+8.10

=> 3x = 20.70

=> x = 20.70/3 = 6.9

Thus, cost of 1 T-shirt = $6.9

cost of 20 T-shirt = 20*$6.9 = $138  (Answer)

kupik [55]
From Matt's formula:
I=P×r×t
P=principle amount (amount invested)
r=rate
t=time
From the information given:
P=$550
r=0.03
t=1
therefore
I=550*0.03*1
I=$16.5

How do you describe a sequence of rigid motions?
Burka [1]

See the explanation

<h2>Explanation:</h2>

Rigid motions are transformations we perform on a figure in order to move it without changing the size or shape of it. They are also called <em>congruence transformations </em>because we can map one figure onto other figure so they will maintain every condition in order to be congruent.

Rigid motions are the following:

  • Reflections: Here we reflect the figure across a line
  • Translations: Here we move the figure either horizontally or vertically
  • Rotations: Here we turn the figure either counterclockwise or clockwise.

So sequence of rigid motions could be any combination we get from the mentioned transformations. For instance:

Perform the transformation of triangle ΔABC following this sequence:

1. Translate the figure 2 units right and 4 units down

2. Reflect the figure across the x-axis

3. Rotate the figure 90 degrees in clockwise direction
