A because you have to subtract 8 and 5 and you get 3 and don’t change the bottom so it’s 3/14

Answer:

3/13

Step-by-step explanation:

8/13 subtract by 5/13. If the denominator is the same, you keep it, don't change it. Just subtract the numerator.

Make sure to simplify, if it is already simplified that will be the answer.

-2x-2+x^2+x+180+-2x-2=180
Dominik [7]

Answer:

x= 4, -1

Step-by-step explanation:

-2x - 2 + x^2 + x + 180 - 2x - 2 = 180

add like terms and put in descending order

x^2 - 3x + 176 = 180

subtract 180 from both sides

x^2 - 3x - 4 = 0

factor out the equation

(x-4)(x+1)=0

solve for x

x-4=0        x+1=0

x=4            x=-1

7 red, 8 yellow, 9 white......total = 24 roses

probability first pick is white : 9/24 
probability second pick is yellow : 8/23

probability of both : 9/24 * 8/23 = 72/552 reduces  3/23 <====

Is 100 in greater than 3yd 1ft
wolverine [178]
1 yard = 36 inches

3 * 36 = 108

1 foot = 12 inches

108 + 12 = 120

So 3 yards and 1 foot is equal to 120 inches.

120 is greater than 100 so 3 yards and 1 foot is greater than 100 inches.

Describe the transformation in the figure below
Keith_Richards [23]

Answer:

A) Reflection.

Step-by-step explanation:

From the figure shown, we can see that the blue triangle is flipped about the x-axis to form the red triangle.

When an object is flipped about a line, then this transformation is called reflection about that line.

Thus, we can say that reflection is taking place in the figure shown in which the x-axis is acting like a mirror. The blue triangle is the pre-image and the red triangle is the image after reflection.

The reflection about x-axis is given by:

Pre-image(x,y)\rightarrow Image(x,-y)

We can check the co-ordinates of the triangles and confirm the the transformation occurring

Points of pre-image triangle:

(0,2),(4,5),(6,2)

Points of image triangle

(0,-2),(4,-5),(6,-2)

Thus, the transformation is reflection.
