Step-by-step explanation:

Answer:

2) -3x+10

4) -4x+10+x

Step-by-step explanation:

Use the distributive property to get rid of the parentheses.

(2 × -2x) + (2 × 5) + x

-4x + 10 +x is correct, but the x's can be combined.

(-4x + x) + 10 = -3x + 10

The perimeter of the triangle is 188.1 m

The perimeter of a triangle can be determined by adding the three lengths of the triangle.

From the image, the coordinates of vertices of the triangle are:

(-3, 3), (-3, -2) and (3, 3)

distance between (-3, 3) and (-3, -2) is:

3-(-2) = 5  (we use y coordinates only because x are the same)

       = 50 m  (Each unit on the map represents 10 meters)

distance between (-3, 3) and (3, 3) is:

3-(-3) = 6    (we use x coordinates only because y are the same)

       = 60 m

distance between (3, 3) and (-3, -2) is:

= √(50² + 60²)     (Pythagoras)

= 78. 1 m

Perimeter = 50 + 60 + 78.1 = 188.1 m

Answer:

50 Nickels, 90 pennys, 100 dimes

Step-by-step explanation:

x = Nickels

x+40+x+x2=240

Add similar elements x+2x+x=4x

4x+40=240

Subtract 40 both sides

4x+40-40=240-40

4x =200

Divide Both sides by 4

4x/4 = 200/4

x=50

Answer:

-112.5

Step-by-step explanation:

2x - 50 = -275

2x = -225

x = - 112.5

Answer:

x = -225/2 (or) -112.5

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

The equation is,

→ -275 = 2x - 50

Then the value of x will be,

→ -275 = 2x - 50

→ 2x - 50 = -275

→ 2x = -275 + 50

→ 2x = -225

→ x = -225/2

→ [ x = -112.5 ]

Hence, value of x is -112.5.

Answer: [tex]\dfrac{7}{15}[/tex]

Step-by-step explanation:

Given

There are 16 girls and 14 boys

The favorable chances that a boy name comes up are 14

Probability is given by the ratio of favorable chances to the total chances

So, the probability that a boy's  name will be pulled is

[tex]\Rightarrow P=\dfrac{14}{14+16}\\\\\Rightarrow P=\dfrac{14}{30}\\\\\Rightarrow P=\dfrac{7}{15}[/tex]

Answer:

X= 2y/49 - 19/49

Answer:

because (x; 83) is a solution to the equation

2y=1/2(98x+38)

=> 2.83 = 1/2(98x + 38)

<=> 4.83 = 98x + 38

<=> 332 = 98x + 38

<=> 98x = 294

<=> x = 3

Answer:

12+n

Step-by-step explanation:

Hi!

8+n-4 = n+4

n+4 = n+4 (Can not be simplified).

(8+n)-4 = n+4

12+n = 12+n (Can not be simplified).

(8-4)+n = n+4

So the answer would be 12+n because it does not equal n+4.

Answer:

of the 36 possible outcomes, only 3 sum to 11 or 12.

Answer:

12 times

Step-by-step explanation:

becuase 60×2÷10=12

Answer:

50 times

Step-by-step explanation:

Total number of faces = total possible outcomes = 8

Number of 2 or 3 on spinner = required outcome = 2

Probability of obtaining a 2 or 3 = required outcome / Total possible outcomes

P(2 or 3) = 2 / 8 = 1/ 4

From 200 ; prediction for the number of 2 or 3

1/4 * 200

= 50 times

Step-by-step explanation:

she gave 5 oranges to her husband .

A statement that links two expressions with an equal sign is called an Equation.

It is given that

Aunt Mansah bought 100 oranges

she bought 4 oranges for 20p

1 is bought at 5p

Let x be the number of oranges she gave to her husband

The remaining oranges were sold at 5 for 40p

1 is sold at 8p

Profit = £2.60

The given data can be used to form equation and solving them will give desired answers

1 pound = 100 pence

( 100 - x) * 8 - ( 100) * 5 = 2.60 * 100

800 - 8x -500 = 260

-8x +300 = 260

8x = 40

x = 5

Therefore she gave 5 oranges to her husband .

4.

Step-by-step explanation:

Step 1: Formula.

[tex]IQR=Q3-Q1[/tex]

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 2: Explain/define.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 3: Order/arrange.

In order to find the median, you must first put the numbers in numerical order.

19, 21, 18, 17, 18, 22, 46

               ↓

17, 18, 18, 19, 21, 22, 46

The lower half of the data set, not including the median of the whole data set, is 17, 18, and 18.

The upper half of the data set is 21, 22, and 46.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 4: Solve.

Next, we find the medians of both sets.

The median of the lower half is 18 (Q1).

The median of the upper half is 22 (Q3).

Lastly, we subtract Q3 from Q1.

[tex]22-18=4.[/tex]

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Step 5: Conclude.

I, therefore, believe the interquartile range of this data set is 4.

Answer:

The answer is below

Step-by-step explanation:

From the image attached, the measurement of the roof is 5 m by 9 m on  both sides. Hence:

Area of roof = 2 (5 * 9) = 90 m²

Since solar panels cost $4.00 per square meter, therefore:

Cost of solar panels = $4.00 per square meter * 90 m² = $360

The area of the front wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) - (4 m * 4 m) = 52 m²

The area of the back wall of the barn = (8 m * 7 m) + (1/2 * 8 m * 3 m) = 68 m²

Area of each side wall of barn = 9 m * 7 m = 63 m²

Total area of wall = 52 m² + 68 m² + (2 * 63 m²) = 246 m²

Cost of shingles = $2.50 for each square meter * 246 m² = $615

Total cost of project = $615 + $360 = $975
