Answer: (-3, -5)

<u>Step-by-step explanation:</u>

-6x +  y =  13  

<u> 6x + 3y</u> = <u>-33 </u>

         4y = -20

       <u> ÷4 </u>     <u>÷4 </u>

          y  =  -5

6x + 3y = -33

6x + 3(-5) = -33

6x - 15 = -33

6x        = -18

x         = -3

*********************************************************************************

Answer: (\frac{1}{3}, 2)

<u>Step-by-step explanation:</u>

9x +  y =  5   →    1(9x +  y =  5)   →    9x +  y =  5

3x - 3y = -5   →  -3(3x - 3y = -5)  →  <u> -9x + 9y</u> = <u>15 </u>

                                                                10y = 20

                                                              <u> ÷10  </u>  <u>÷10 </u>

                                                                   y = 2

9x +  y =  5

9x + (2) = 5

9x        = 3

 x         = \frac{1}{3}

The rectangles below have the same perimeter.
attashe74 [19]

Answer:

32 mm²

Step-by-step explanation:

perimeter of left rectangle = 2(9 mm + 3 mm) = 24 mm

length of right rectangle = L

perimeter of right rectangle = 2(L + 4 mm) = 2L + 8

perimeter of right rectangle = 24 mm

The perimeter of the right triangle is 2L + 8 and also 24, so 2L + 8 must equal 24. We can solve for L and find the length of the right rectangle.

2L + 8 = 24

2L = 16

L = 8

area of right triangle = length × width

area = 8 mm × 4 mm

area = 32 mm²

There are black, blue, and white marbles in a bag. The probability of choosing a black marble is 0.36. The probability of choosi
Gala2k [10]

Answer: c) 0.75

Step-by-step explanation:

Given : The probability of choosing a black marble is P(Black)= 0.36.

The probability of choosing a black and then a white marble is P( Black and white) = 0.27.

Then by conditional probability ,

The probability of the second marble being white if the first marble chosen is black = P(\text{white }|\text{Black})=\dfrac{\text{P( Black and white)}}{\text{P(Black}}

=\dfrac{0.27}{0.36}=\dfrac{27}{36}=0.75

Therefore , the probability of the second marble being white if the first marble chosen is black = 0.75
