Answer:

Step-by-step explanation:

If we take the number as 7 so 3 times 7 is

3 x 7 = 21

Subtracted by 6 = 21 - 6= 15

So the number is 7

Answer:

7

Step-by-step explanation

Add the subtracted value to the other given value

15+6=21

Since we know it is 3 times the number, divide by 3 to get the number

21/3=7

Check:

21=3x7

21=21

Answer:

256/39 or 6 22/39

We know the price of parking and we know what they paid in total. There are 5 members with the unknown price.

Answer:

B

Step-by-step explanation:

You're trying to find how much a ticket, which is t. you need 5 tickets for the family, plus the twelve dollar fee which is there anyways for the car, and it add up to 132. subtract 12 from 132 and you get 120. 120 divided by 5 is 24. so 24 dollars for a ticket, but the equation you would need is 5t+12=132

Answer:

S'(-3, 7)

Step-by-step explanation:

The coordinate of point S' will be (-5, 1).

A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.

The rules for finding the reflection of a point in y-axis are:

(i) Change the sign of abscissa, i.e. x-coordinate.

(ii) Retain the ordinate i.e., y-coordinate.

Therefore, when a point is reflected in the y-axis, the sign of its abscissa changes.

According to the given question.

We have a triangle QRS.

The coordinates of points Q, R, and S are (4, 2), (5, 1) and (3, 7) respectively.

Since, the triangle QRS is reflected across the y-axis .

Therefore, the coordinate of S' is given by

The sign of abscissa or x-coordinate of (5, 1) changes so, 5 changes to -5.

And the ordinate i.e. 1 will remain same.

Therefore, the coordinate of point S' will be (-5, 1).

Option D (6)

Step-by-step explanation:

6-4 is equal to 2

Answer:

in 4 years

Step-by-step explanation:

because you should find the 20% of 150

150×20=3000

3000÷100= 30

so 20% of 150 is 30

then you keep adding 30 to the results till you reach 300

The equation is 150+30x=300 and it takes 3 years for the company to earn $300.

Given that, a small business begins with $150 and grows by 20% each year.

We need to find when will the company's income by $300.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Now, 20% of 150=30

Let x be the number of years.

So, f(x)=150+30x

⇒150+30x=300

⇒30x=150

⇒x=3

The equation is 150+30x=300 and it takes 3 years for the company to earn $300.

Answer:

Using Pyhagoras theoram,

(H)^2 = (B)^2 + (P)^2

B = 13 in

P = 5 in

[tex](h)^{2} = (13)^{2} + {(5)}^{2} \\ = > (h)^{2} = 169 + 25 \\ = > (h)^{2} = 194 \\ = > h = \sqrt{194} \\ = > h = 13.92[/tex]

Hence, the missing side is 13.92 inhes.

Answer:

13.93

Step-by-step explanation:

[tex]5^{2} + 13^{2} = c^{2}[/tex]

[tex]25 + 169 = 194 = c^{2}[/tex]

[tex]\sqrt{194} = c^{2}[/tex]

[tex]13.92838827718 = c[/tex]

Answer:

width of given rectangle = 6 cm

length of given rectangle =  4 cm

Step-by-step explanation:

Let the breadth be x cm

given that

The length of a rectangle is eight centimeters less than twice its width

length of rectangle in terms of x =  2(breadth ) - 8 =  2x - 8

we know perimeter of rectangle is given = 2(l + b)

thus, perimeter of given rectangle is = 2 ( x +  2x - 8) = 6x - 16

also given perimeter of the rectangle is 20 centimeters

thus,

6x - 16 = 20

6x = 20 + 16 = 36

x = 36/6 = 6

Thus,

width of given rectangle = 6 cm

length of given rectangle = 2*6 - 8 = 4 cm

Answer:

23.55

Step-by-step explanation:

To calculate the area I did the following equation

area = 3.14 (r) (r)

area = 3.14 (3) (3)

area = 28.26

The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.

The equation for 5/6 out of 28.26 is

28.26 (5/6) = 23.55

So the final answer is (a.) 23.55 sq. ft.
