Let x = cost of one t-shirt

Let y = cost of one sweatshirt

Jayden: 9x + 3y = $420

Carson: x + 6y = $296. Multiply Jayden's equation by -2

Jayden: -18x - 6y = $-840

Carson: x + 6y = $296. Add the equations together to eliminate variable y.

New equation: -17x = $-544. Divide each side by -17.

x = $32. Plug this value into one of the original equations.

32 + 6y = $296. Subtract 32 from each side.

6y = 264. Divide each side by 6.

y = 44.

Plug both your x and y value into one of the equations to ensure they're correct.

9(32) + 3(44) = 420

420 = 420.

x = 32

y = 44.

Find the value of x in the triangle shown below
olga nikolaevna [1]

Answer:

102

Step-by-step explanation:

it is an isosceles triangle as two sides are equal i.e 3.3 so angles opposite to equal sides are also equal so 39 plus 39 plus x = 180°

78 plus x =180

x=180-78

x=102°

hope it helps

The area of a rectangle is 256.5m.  If the length is 18m what is the perimeter of the rectangle?
irga5000 [103]
The area of a rectangle equals length times height. (A=LH)

A=256.5 L=18

Plugging in the numbers into the equation, you get 256.5=18H. (like I substituted the numbers in)

next if you divided both sides by 18, it will cancel out the 18 in the 18H side of the equation.

So, it is 256.5/18 equaling H

256.5 divided by 18 is... 14.25

That means the height is 14.25 an the length is 18.

the perimeter is all of the sides added together. in a rectangle, the sides opposite each other are the same.

So you have two sides that are 14.25 and two that are 18 meters long.

14.25+14.25+18+18 equals the perimeter then.

So the answer would be... 64.5!

ella [17]

Answer: if you have infinity points, which i will asume are the events, they cant have the same probability because then the probability will not be normalized, because in graph of prob vs variable, you will se infinite area under the curve if the probability is constant.

And yes, can all points have positive probability of occurring, but besides you medium value (the bell for example) you will see an asintotic decrease to the zero.
