Answer:

13+n

Step-by-step explanation:

Answer:

13 + n

Step-by-step explanation:

This is because the known number is 13 times more than n so if the value of n is found, _+ 13_ will give you the final answer.

Answer:

[-0.25 1.25]

[ ]

[-0.75 2.75]

If not satisfied than..

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.

4

And than subtract..

And you will get the inverse matrix

If the answer comes same than that's the answer for inverse matrix

Thank you.

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:

1860 yards

300 feet = 100 yards

1760 + 100 = 1860 yards

Answer:

The answer is –2

Step-by-step explanation:

The reason its –2 is because on a number line

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

Answer: f(10) = 290

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

Given expression

f(x) = 3x² - x

Substitute values into the expression

f(10) = 3(10)² - (10)

Simplify exponents

f(10) = 3(100) - (10)

Simplify by multiplication

f(10) = 300 - 10

Simplify by subtraction

f(10) = [tex]\boxed{290}[/tex]

Answer:

SELLING PRICE OF CYCLE = 2250RS

LOSS MAN SUFFERED = 50RS

Step-by-step explanation:

COST PRICE = SP + LOSS

CP = 2250 + 50

CP = 2300 RS

FORMULA OF PROFIT = SP - CP

TO MAKE PROFIT OF 80 RS

80 = SP - 2300

 SP = 2380 RS

HE SHOULD SELL THE CYCLE AT 2380 TO MAKE PROFIT OF 80 Rs

Answer:

rs 2380

Step-by-step explanation:

→ Add rs 50 to the selling price to not make a profit or loss

2250 + 50 = 2300

Answer:

Step-by-step explanation:

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.

working hours a day = 5 hours 30 minute

total working hours = 5 days × 5.5 hours

= 27 hours 30 minute

pay per hour = $12

total gross pay a week = 27.5 × $12

The required percentage of the 30 intermediate-level questions is 20%.

Given that,
Practice questions for a textbook are marked with difficulty levels of easy, Intermediate, and difficult. 30 of the 149 practice questions are rated as intermediate, approximately what percentage of the questions are intermediate level is to be determined.

the percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
the required percentage of the intermediate difficult question,
= 30 / 149 * 100
≈ 0.20 * 100
≈ 20%

Thus, the required percentage of the 30 intermediate level question is 20%.

Here, we need to subtract the quantity of tin from the quantity of iron in order to find how much more iron Trista has than tin

The quantity of iron Trista has more than tin is 7.17 mg

Quantity of iron = 8 mg

Quantity of tin = 0.83 mg

Quantity of iron Trista has more than tin = Quantity of iron - Quantity of tin

= 8 mg - 0.83 mg

= 7.17 mg
