On the coordinate plane below, quadrilaterals TRAP and HELP are similar to each other.

The existing dimensions of TRAP are increased and as a result, the original area of the quadrilateral is doubled. Consider the changes in the area of TRAP and determine the new ratio of the areas of TRAP to HELP.
A. 4:1
B. 32:1
C. 16:1
C. 8:1

Answer:

x=15/4,y=-8.25

Step-by-step explanation:

Well to begin with it make both y's equal so multiply the first equation by 3 making it into: 6.6x+3y=-12. next subtract this new equation by the other one making it one equation as, 1.6x=-6, simplify to get: x=15/4, or 3.75 input that into one of the equations the secound one would be easier to make it 18.75+3y=-6 simplify again, 3y=-24.75 than you get y as y=-8.25

Step-by-step explanation:

- Area of rectangle = length * width

[tex]11 = 3\frac{2}{3} *w\\\\- rearrange and divide\\ 11 \\ by \\\\ 3\frac{2}{3}\\\\ = 3[/tex]

The side length of the rectangle is given by the equation L = 3 m

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the value of A is

A = 11 m²

Now , the width of the rectangle W = 3 2/3 m

Let the length of the rectangle be L

Now , Area of Rectangle = Length x Width

Substituting the values in the equation , we get

11 = L x ( 3 2/3 )

11 = L x ( 11/3 )

Divide by 11 on both sides of the equation , we get

L / 3 = 1

Multiply by 3 on both sides of the equation , we get

L = 3m

Therefore , the value of L is 3 m

Hence , the length of the rectangle is 3m

Answer:

x=50

Step-by-step explanation:

A= 30+2x

B= x

Supplementary angles are angles that always add up to 180 degrees.

therefore, A + B=180 degrees

30 + 2x + x = 180: Now we solve

30 + 3x =180

subtract 30 from both sides

3x=150

divide by 3

3x/3 = 150/3

x= 50

Answer:

It's going down 2 because it's -2

Step-by-step explanation:

y2 - y1

----------           This should be the formula

x2 - x1

However, you didn't give us two coordinates just a linear equation.

Rate of change finds you the slope and the slope is -2.

Answer:

B

Step-by-step explanation:

Multiply each ratio by the same number

4x3=12 7x3=21

The number of players on each team could be; B. 12 soccer players and 21 baseball players.

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b. Remember that the ratio should always be taken of quantities with the same unit of measurement. Also, the ratio is a unitless(no units) quantity.

We have been given that the ratio of soccer players to baseball players on two school teams is 4 to 7.

That is; 4: 7

Then Multiply each ratio by the same number.

4 x 3 = 12

7 x 3 = 21

Therefore, the number of players on each team could be; B. 12 soccer players and 21 baseball players.

Answer:

1/5 = 0.2 so, she can drink 0.1 of a gallon each day

to turn a fraction into a decimal you should do..

1/5 since 5 can't go into 1 you add a 0 to the 1 making it a 10 and move the decimal point, since 5 goes into 10, 2 times, we get 0.2

Answer:

True True False True

Step-by-step explanation:

You would substitute the value for x and the value for y into both equations and see if the sign holds true.

So for number 1:

x=3, y=-2;

y ≤ x -3        

-2 ≤ x - 3

-2 ≤ -1

y ≥ -x - 2

-2 ≥ -3 - 2

-2 ≥ -5

Number 1 is true because the equations are true ^^

Do this for every problem so it would be:

1. True

2. True

3. False

4. True

Answer:

Part 1: Number of extra round balloons that long balloons = 12 balloons

Part 2 : Leftover blown-up balloons = 247 balloons

Note: The question is incomplete. The complete question is given below:

A clown bought 5 bags of round balloons with 24 balloons in each bag. the clown also bought 3 bags of long balloons with 36 balloons in each bag.

Part 1

How many more round balloons than long balloons did the clown buy?

Part 2 out of 2

The clown also bought 3 bags of heart-shaped balloons with 14 balloons in each bag. when the clown blew up all of the round, long, and heart-shaped balloons, 23 balloons burst. How many blown-up balloons were left? explain your answer.

Step-by-step explanation:

Step 1 : Finding the total number of each balloon

Round balloon = 5 × 24 = 120 balloons

Long balloons = 3 × 36 = 108 balloons

Heart-shaped balloons = 3 × 14 = 42 balloons.

Part 1:

Number of extra round balloons that long balloons = 120 - 108

Number of extra round balloons that long balloons = 12 balloons

Part 2:

Total number of balloons = 120 + 108 + 42 = 270 balloons.

Number of burst balloons = 23

Leftover blown-up balloons = 270 - 23 Leftover blown-up balloons = 247 balloons

Answer:

26.25 minutes

Step-by-step explanation:

Given that :

Number of pages (p) read by Elias can be modeled by the function ;

p = 45m + 18

Where P = Number of pages ; m = number of minutes

Number of minutes it will take to read a total of 39 pages

p = 4/5m + 18

39 = 4/5m + 18

39 - 18 = 4/5m

21 = 4/5m

4m = 21 * 5

4m = 105

m = 105 / 4

m = 26.25

x = -7

Step-by-step explanation:

4x - 9 = 7x + 12

~Add 9 to both sides

4x = 7x + 21

~Subtract 7x to both sides

-3x = 21

~Divide -3 to both sides

x = -7

Best of Luck!

Answer:

x = -7

Step-by-step explanation:

Combine like terms: (Subtract 4x from both sides, and subtract 12 from both sides)

4x - 9 = 7x + 12

-9 - 12 = 7x - 4x

-21 = 3x

Divide by 3:

-21 = 3x

x = -21 / 3

x = -7

Plug in to check your answer:

4x - 9 = 4(-7) - 9 = -37

7x + 12 = 7(-7) + 12 = -37

Answer:

-3

Step-by-step explanation: Simplifying

2x + 6 = 0

Reorder the terms:

6 + 2x = 0

Solving

6 + 2x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6' to each side of the equation.

6 + -6 + 2x = 0 + -6

Combine like terms: 6 + -6 = 0

0 + 2x = 0 + -6

2x = 0 + -6

Combine like terms: 0 + -6 = -6

2x = -6

Divide each side by '2'.

x = -3

Simplifying

x = -3

Answer:

2x < 6

=> x < 6/2

=> x < 3
