-2x + 4y - 12
-x - 4

Answers

Answer 1

Answer:

-4x+4y+2

Step-by-step explanation:

You simplify the equation. So -x plus -2x plus -x = -4x. 4y=4y. 19 plus -12 plus -4 = 2.

What is inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

The sample of the red candies in the bag:

Red: 2 1 4 2 1 2 1 0 1 3 3 1

Total = 21 red candies in the bags.

There are only 3 green candies in the 1-pound bag.

So, 21 > 3.

Therefore, the number of red candies in the bag is greater.

find the areas of the trapezoid

Answers

Answer:

Formula for the area of a trapezoid;

A = 1/2 (b1 + b2) x h

Where b1 represents base one, and b2 is base two. And H displays as the height.

First, we must figure out our bases and then our height.

If we look at the trapezoid, we can see the bottom base(which will be our base 1) is 4. Our upper base is 2, which we will consider our base 2.

Our height is 4, because the distance between our bases is 4.

So now we plug these values into our formula;

A = 1/2 (b1 + b2) x h

A = 1/2 (4 + 2) x 4

Now solve:-

A = 1/2(6) x 4

A = 6/2 x 4

A = 3 x 4

A = 12

Answer:

48 inches

Step-by-step explanation:

It is going by 2 so when you look at the lines inside the shape going up and down you see 4 lines. 4 times 2=8( because it is going by 2). Then you see the lines in the shape going horizontal it states 2 lines is equal to 2 so then you do 2 times 2=4(because it is going by two). You then do 8 times 4=32 and 8 times 2=16 32+16=48.

For the school’s sports day, a group of students prepared, 21 1/2 liters of lemonade. At the end of the day, they had 258 liters left over. How many liters of lemonade were sold?

Answers

Answer:

83 (maybe)

Step-by-step explanation:

21 1/2 = (actual number) = 21,500

(left over = 258 ÷ 21,500 or 21,500 ÷ 258)

21,500 ÷ 258 = 83

So, the answer is 83.

I'm not entirely sure if my answer is correct.

Milan uses a probability simulator to roll a six-sided number cube 100 times and to flip a coin 100 times. The results of the experiment are shown below:


Number on the Cube Number of Times Rolled
1 10
2 8
3 33
4 29
5 11
6 9


Heads Tails
29 71


Using Milan's simulation, what is the probability of rolling a 5 on the number cube and the coin landing on tails?
fraction 11 over 10,000
fraction 71 over 10,000
fraction 82 over 10,000
fraction 781 over 10,000

Answers

Answer:

781/10000

Step-by-step explanation:

These are independent events so we can multiply the probabilities

P(5 on the coin ) = 11/100

P( tail on the coin) = 71/100

P( 5 and tails) = 11/100 * 71/100

                      = 781/10000

Answer:

the probability of rolling a 5 on the number cube and the coin landing on tails is 781 over 10,000

Step-by-step explanation:

T= 71 times

11= 5 rolled

71/100 * 11/100 = 781/10000

Solution:

To find the area of a composite shape, we need to break the composite shape into smaller "known" shapes.

⇒ Area of composite figure = Area of quarter circle + Area of all rectangles...

Step-1: Find the radius of the quarter circle

Radius of quarter circle = (8 + 4 + 4) - (9)Radius of quarter circle = (16) - (9)Radius of quarter circle = 7 meters

Step-2: Find the area of the quarter circle (Q)

Area of circle = πr²Area of quarter-circle = πr²/4Area of quarter-circle = (3.14)(7²)/4Area of quarter-circle = (0.785)(49)Area of quarter-circle = 38.465 m²

Step-3: Find the area of rectangle₁ (L)

Area of rectangle = LBArea of rectangle₁ = (21)(8)Area of rectangle₁ = 168 m²

Step-4: Find the area of rectangle₂ (M)

Area of rectangle = LBArea of rectangle₂ = (4 + 4)(21 - 18)Area of rectangle₂ = (8)(3)Area of rectangle₂ = 24 m²

Step-5: Find the area of rectangle₃ (S)

Area of rectangle = LBArea of rectangle₃ = (4)(8)Area of rectangle₃ = 32 m²

Step-6: Find the area of the composite figure.

Area of composite figure = Area of quarter circle + Area of all rectangles...Area of composite figure = 38.465 + (168 + 24 + 32)Area of composite figure = 262.465 m²
