equation 2: -9x\2 + 27

equation 3: 4.5x + 16

equation 4: 4.5x - 16

Step-by-step explanation:

1) 3(1.5x+9) = 4.5x +27 =-9
4.5x+27=-9
4.5x=-36
x=-8

2) -9(1/2x-3) = -4.5x +27 =45
-4.5x+27=45
-4.5x=18
x=-4

3) 2(2.25x+8) = 4.5x+16=11.5
4.5x+16=11.5
4.5x=-4.5
x=-1

4) 8.5x - 2(2x+8) = 8.5x -4x -16 = 4.5x-16=11

The composite figure is made up of three simpler shapes. What is the area of the figure?

A. 80
B. 49
C. 68
D. 74

Answers

Answer: I’m pretty sure it’s 80

Step-by-step explanation:

Because the very top triangle is 4x3 which is 12 then the rectangle under it is 6x3 which is 18 then the triangle under that is 5x3 which is 15 and the triangle on the left is also 15 and the square in the middle is 4x5 which is 20 and add it all up 12+18+15+15+20=80 sry if that’s confusing.

Answer:

74 is the answer

Step-by-step explanation: You should find the area of each shape and add all the areas together to get the full area of the shape.

(base x height)+(length x breath)+(1/2 x base x height)
(10x5)+(6x3)+(1/2x3x4)

50+18+6

74 ← this is the full area of the shape

and, remember when finding the area of a triangle you should always multiply 1/2 too for example- ( 1/2 x base x height )

Ahat is the area of this quadrilateral?

A,B,C,D

Answers

Answer:

A. 12 square feet

Step-by-step explanation:

So it's easier to find the area when you split the shape into 2 parts, and they already did that for you. So basically you find the area of both triangles and add them together. The formula for a triangle is base x height divided by 2. You don't have to do that because there are 2 triangles with the same base and height so you don't have to divide it by 2. 3 x 4 = 12, so A. 12 square feet is your answer.

the answer is A.) 12 square feet

Renee hiked for 7 3/4 miles. After resting, Renee hiked back along the same route for 6 1/4 miles. How many more miles does Renee need to hike to return to the place where she started? Represent your answer as a simplified mixed number, if necessary.

Answers

Answer:

Renee will need to hike 1 1/2 more miles.

Step-by-step explanation:

If she hiked to her spot of 7 3/4 miles, she would need to hike another

7 3/4 more miles back. So, if she has hiked back 6 1/4 miles so far, you would subtract 7 3/4 - 6 1/4 to get 1 1/2 more miles!

The verticals of a triangle are (2,5) (1,2) (3,1) to see once reflect the triangle in the x-axis and then rotate the triangle 90 degrees counterclockwise about the origin. what are the coordinates of the image.

Answers

Answer:

(5,2) (2,1) (1,3)

Step-by-step explanation:

First, reflect the image over the x-axis. This affects the y of each point to become negative, and moves the triangle from quadrant I to quadrant IV. This changes the points to be (2,-5) (1,-2) (3,-1).

Next, when rotating the triangle counterclockwise about the origin, the easiest way to describe what this does to the points is that it switches the numbers for x and y, and makes all of them positive. This is because the rotation ends up moving the coordinates back into quadrant I, so they're positive. However, the rotation does switch up the points a bit. So now, the points are (5,2) (2,1) (1,3).

Answer: are (5,2) (2,1) (1,3).

The markup percentage regarding the sale of the good will be 136%.

How to calculate the percentage?

From the information given, the initial cost is $55.00 and the new price is $130.19. The increase in percentage will be:

= (130.19 - 55)/55 × 100

= 75.19/55 × 100

= 136%

Therefore, the markup percentage regarding the sale of the good will be 136%.
