Answer:

x = 5 unit

NM = 20 unit

OL = 20 unit

Step-by-step explanation:

Given:

LMNO is parallelogram

NM = x + 15

OL = 3x + 5

Find:

x and NM and OL

So,

NM = OL

x + 15 = 3x + 5

2x = 10

x = 5

So,

NM = x + 15 = 5 + 15 = 20

OL = 3x + 5 =3(5)+5 = 20

Answer:

Linear equation : y = 2.50h + 5

Step-by-step explanation:

Given that:

Fee for renting roller blades = $5

Per hour charges = $2.50

Let,

h be the number of hours roller blades were rented

y be the total amount

Total amount = Per hour charges * Number of hours + Flat fee

y = 2.50h + 5

Hence,

Linear equation : y = 2.50h + 5

Answer:

9·x² - 36·x = 4·y² + 24·y + 36 in standard form is;

(x - 2)²/2² - (y + 3)²/3² = 1

Step-by-step explanation:

The standard form of a hyperbola is given as follows;

(x - h)²/a² - (y - k)²/b² = 1 or (y - k)²/b² - (x - h)²/a² = 1

The given equation is presented as follows;

9·x² - 36·x = 4·y² + 24·y + 36

By completing the square, we get;

(3·x - 6)·(3·x - 6) - 36 = (2·y + 6)·(2·y + 6)

(3·x - 6)² - 36 = (2·y + 6)²

(3·x - 6)² - (2·y + 6)² = 36

(3·x - 6)²/36 - (2·y + 6)²/36 = 36/36 = 1

(3·x - 6)²/6² - (2·y + 6)²/6² = 1

3²·(x - 2)²/6² - 2²·(y + 3)²/6² = 1

(x - 2)²/2² - (y + 3)²/3² = 1

The equation of the hyperbola  is (x - 2)²/2² - (y + 3)²/3² = 1.

Answer:

Ml is 30 ft beco it help in pi

Answer:

m = 28

Step-by-step explanation:

The given expression is :

0.1(0.5m+6)=2

Step 1.

Use distributive property:

0.1(0.5m) +0.1(6) = 2

0.05 m+ 0.6 = 2

Step 2.

Subtract 0.6 both sides

0.05 m+ 0.6 -0.6= 2 -0.6

0.05 m = 1.4

or

0.5 m = 14

Step 3.

Divide both sides by 0.5

[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]

Gabi's third step is not correct. It should be m = 28 instead of m = 7.

Answer:

12 pounds

Step-by-step explanation:

We know that the candy costs $4 per pound

We also know that he will only spend up to $48

We can represent this as an equation:

4x = 48

Where as x = number of pounds

Solve the equation to find how many pounds he can buy.

4x = 48

Divide both sides by 4

x = 12

This means that Kareem can buy 12 pounds

The Mean Value of a Data Set

The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:

[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]

Where xi is the value of each data and n is the total number of values.

We are given the average weight of n=5 marathon runners:

[tex]\bar x=92[/tex]

Multiplying the formula by n and expanding the sum:

[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]

We are given the weighs of four of the runners:

[tex]5*92=89+95+90+90+x_5[/tex]

[tex]460=364+x_5[/tex]

Solving for x5:

[tex]x_5 = 460-364=96[/tex]

Jordin weighs 96 pounds

Answer:

-9 1/4

Step-by-step explanation:

So what I did was that I put it this for which was -((5+3)+(3/4+1/2)

which then you would get -(8+(3/4+1/2)) which gives you -(8+5/4) because you would convert the 1/2 into 2/4 making it to get 5/4. So then you add the -(8+5/4) which gives you -9 1/4.

Hope this helped!

Answer:

the percent of people that end up coming as error is 12%

Chase made a miscalculation of 52.08% percent.

The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.

Given that, Chase anticipated that just 23 people would attend the event; however, 48 individuals showed up.

The general formula for percentage error:

Percentage Error(%e) = ((Estimated Number – Actual Number)/ Actual number) x 100.

Hence,

Percentage error done by chase = (23 - 48) * 100/48

Percentage error done by chase = -52.08%

Therefore, the Percentage error done by chase is 52.08%
