Answer:

25%

Step-by-step explanation:

125.00x = 93.75

x = 93.75 / 125 = 0.75

meaning that 93.75 is 75% of 125

and, therefore, the item was discounted 100 - 75 % = 25%

Answer:

8 and 32

Step-by-step explanation:

let daughter's age be x then Meena's age is 4x

2 years ago daughter's age was x- 2 and Meena's age was 4x - 2

Meena was 5 times her daughter's age then , so

4x - 2 = 5(x - 2)

4x - 2 = 5x - 10 ( subtract 4x from both sides )

- 2 = x - 10 ( add 10 to both sides )

8 = x

Thus

daughter is 8 years and Meena is 4 × 8 = 32 years

The Equation is 25x-47500 as a function of the number of years since 1990.

To find equation for the number of students .

Statement that the values of two mathematical expressions are equal.

Given that:

The number of students in high school has been increasing linearly since 1990.

In 1997, 1125 students and in 2000, there were 1200 students.

Increase the number of students in 1997-2000

=1200-1125=75

In 3 years 75 student increased

In 1st years 25 student increased

number of students that will  increasing  in 1990=25

Equation=(x-1900)*25

Equation=25x-47500

where x is date/year

So, the Equation is 25x-47500 as a function of the number of years since 1990.

Answer:

x = 2

Step-by-step explanation:

Given

[tex]\frac{3(6x+8)}{4}[/tex] = 15 ( multiply both sides by 4 to clear the fraction )

3(6x + 8) = 60 ( divide both sides by 3 )

6x + 8 = 20 ( subtract 8 from both sides )

6x = 12 ( divide both sides by 6 )

x = 2

The value of x in the equation is 2

The equation given :

3(6x + 8) / 4 = 15

Multiply both sides by 4

3(6x + 8) = 15 × 4

3(6x + 8) = 60

Open the bracket

18x + 24 = 60

18x = 60 - 24

18x = 36

x = 36/18

x = 2

The value of x in the equation is 2

Answer:

97

Step-by-step explanation:

388 (number of tickets) / 4 (number of groups (adults, and the 3 times as many kids))

If the number of student tickets sold was three times the number of adult tickets sold, 97 adult tickets were sold.

Let's assume the number of adult tickets sold is 'x.'

According to the information given, the number of student tickets sold was three times the number of adult tickets sold. So, the number of student tickets sold is 3x.

The total number of tickets sold is the sum of the adult and student tickets, which is 388:

x + 3x = 388

Now, combine like terms:

4x = 388

To find the value of 'x,' divide both sides of the equation by 4:

x = 388 / 4

x = 97

To verify the result, let's find the number of student tickets:

Number of student tickets = 3 * 97 = 291

Now, let's add the adult and student tickets:

97 (adult) + 291 (student) = 388

The result checks out, and we have 97 adult tickets and 291 student tickets, which together sum up to the total of 388 tickets sold for the school play.

Answer:

hope this helps you

have a great day

Step-by-step explanation:

Since the integers are consecutive,

let the smaller one be x

then the larger will be x+1

Now their sum is -15

x+x+1=-15

2x=-15-1

2x=-16

x=-8

Therefore the smaller is -8 and the larger is -7

Now when one is added to the smaller integer it becomes -8+1=-7

If 2 is subtracted from the larger one it becomes -7-2=-9

their product therefore becomes -9×-7=63

You can write it in other way as show in step by step

Step-by-step explanation:

Step 1:

First of all find the determinate.

Cross multiply the number 11 ✖ -1

= -11 ---eq1

And now cross multiply the number 3 ✖ - 5

= -15 ---eq2

Now we use eq 1 and 2

detA = (-11)-(-15)

Minus cancels minus

So it becomes

detA = -11 + 15

= 4

Step 2:

We find adjacent of the given.

[11 -5]

adjA= [ ]

[3 -1 ]

We change the places. The number 11 goes to in place of -1. -1 goes in place of 11.

And we change the signs of -5 and 3. -5 becomes 5 and 3 becomes -3.

We get

[-1 5]

adjA = [ ]

[-3 11]

Step 3:

Now we use the following formula

1

A^-1 = -------- adjA

detA

1 [-1 5]

A^-1 = ------- [ ]

4 [-3 11]

And now multiply

1

---- with each number of adjA.

Answer:

F:53cm by 102cm

Step-by-step explanation:

The perimeter of a rectangle can be seen as 2l + 2w, with the length being l, and the width being d. If the ratio is 3:2, then 3+2= 5 parts would be the sum of the length and the width, This is half of the perimeter 2(l+w), so 510÷2 = 255. One part would be 255÷5=51.

If you put it into the ratio, effectively it is:

Length:Width

3×51:2×51

153  :102

Therefore the dimensions are 153cm by 102cm, which is F.

Answer:

-7

Step-by-step explanation:

Check (optional):

2(-7) - 4 = -18

-14 - 4 = -18

-18 = -18 so this is correct

Answer: WX = 4

Concept:

Here, we need to know the idea of segment addition postulate.

The Segment Addition Postulate states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.

Solve:

Given information

VX = 18

VW = 14

Given expression deducted from the segment addition postulate

WX = VX - VW

Substitute values into the expression

WX = 18 - 14

Simplify by subtraction

WX = 4
