One number was divided by 15, followed by this quotient being multiplied by 2. Next, the product was added to 9. The total sum was 7, so what was the first divisor?

Answer:

question 5) 43

question 6) 38

question 3) 107

question 4) 82

Step-by-step explanation:

question 5 and 6 add up to 90 so 90-47=43

and questions 3 and 4 add up to 180 so, 180-73=107

qnd 52+46 =98 so 180-98=82

Answer:

350:75?

fraction form: 350/70  

Step-by-step explanation:

9514 1404 393

Answer:

  4 feet

Step-by-step explanation:

Desmos is useful for finding the answer to this. The problem statement tells you the angle with the x-axis is 75°. If we put the ladder in the first quadrant, the slope will be -tan(75°). We can raise its end to the 15 ft level by making the y-intercept be 15. Then the x-intercept answers the question: 4 ft.

_____

Additional comment

The angle mode needs to be set to Degrees in the Desmos settings for this equation to produce the correct graph.

Answer:

[tex]-1.5x - 3.5y =- 31.5[/tex]

Step-by-step explanation:

Given

AB: [tex]-7x + 3y = -21.5[/tex]

[tex]PQ(x_1,y_1) = (7,6)[/tex]

Required

Determine the equation of PQ

First, we calculate the slope of AB:

[tex]-7x + 3y = -21.5[/tex]

Make 3y the subject

[tex]3y = 7x - 21.5[/tex]

Make y the subject

[tex]y = \frac{7}{3}x - \frac{21.5}{3}[/tex]

An equation has the general form:

[tex]y = mx + b[/tex]

Where m = slope

So:

[tex]m = \frac{7}{3}[/tex] -- Slope of AB

From the attached diagram, we can see that PQ is perpendicular to AB.

This means that, the relationship between their slope is:

[tex]m_2 = -\frac{1}{m_1}[/tex]

Substitute 7/3 for m1

[tex]m_2 = -\frac{1}{7/3}[/tex]

[tex]m_2 = -\frac{3}{7}[/tex]

The equation of PQ is then calculated as:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = m_2 = -\frac{3}{7}[/tex]

and

[tex]PQ(x_1,y_1) = (7,6)[/tex]

So, we have:

[tex]y - 6 = -\frac{3}{7}(x - 7)[/tex]

Multiply both sides by 7

[tex]7(y - 6) = -\frac{3}{7}(x - 7)*7[/tex]

[tex]7y - 42 = -3(x-7)[/tex]

Open bracket

[tex]7y - 42 = -3x + 21[/tex]

Collect Like Terms

[tex]3x + 7y = 42 + 21[/tex]

[tex]3x + 7y = 63[/tex]

Divide through by -1/2

[tex]-\frac{1}{2}(3x + 7y) = -\frac{1}{2}*63[/tex]

[tex]-1.5x - 3.5y =- 31.5[/tex]

The equation of PQ is: [tex]-1.5x - 3.5y =- 31.5[/tex]

Answer:

B. -1.5x − 3.5y = -31.5

Answer:

Mean:8

Median:8.5

Mode:9,4

Step-by-step explanation:

Mean Steps:

mean(5,9,7,12,6,4,10,8,14,9,4)

To find the mean of the set 5,9,7,12,6,4,10,8,14,9,4 first add the members together.

5+9+7+12+6+4+10+8+14+9+4=88

The mean (average) of the set 5,9,7,12,6,4,10,8,14,9,4 is found by dividing the sum of its members by the number of the members, in this case 11.

88/11 = 8

Mode Steps:

Mode(5,9,7,12,4,10,8,14,9,4)

The mode of a set is the value that appears most often. The mode can have more than one value if two or more values appear the same number of times and more times than any other values in the set.

mode(5,9,7,12,4,10,8,14,9,4)

Putting the numbers in order can make it easier to find the mode because values that appear more than once will be next to each other.

4,4,5,7,8,9,9,10,12,14

In this case the mode has more than one value because 9 and 4 both appear 2 times, more often than any other values.

mode(4,4,5,7,8,9,9,10,12,14)=9,4

m=s(q_2-q_1)

m/s=q_2-q_1

q_2=m/s  +  q_1

[tex] \tt \dashrightarrow m = s(q_2 - q_1) [/tex]

[tex] \tt \dashrightarrow \dfrac{m}{s} = q_2 - q_1[/tex]

[tex] \tt \dashrightarrow \dfrac{m}{s} + q_1= q_2[/tex]

[tex] \tt \dashrightarrow q_2 = \dfrac{m}{s} + q_1[/tex]

[tex] \large \underline{\boxed{\bf{q_2 = \dfrac{m}{s} + q_1}}}[/tex]

Hence, value of [tex] \tt q_2 = \dfrac{m}{s} + q_1[/tex]

Answer:  Equation that represents this situation is 5(x+17) = 1495,

Price of one ticket is 282

Step-by-step explanation:

Here x represents the price of one ticket,

Also, a person bought travel insurance that costs $17 per ticket.

Hence, the total cost of a person = x + 17

⇒ The total cost of 5 person = 5 ( x + 17 )

But, According to the question,

5 ( x + 17 ) = 1495

⇒ x + 17 = 299

⇒ x = 299 - 17

⇒ x = 282

Hence, the price of one ticket = $ 282

Answer:

Step-by-step explanation:

the answer is

[tex]x = \sqrt{3} [/tex]

Answer:

C) x = -2 ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

3x² + 12x - 9 = 0

divide through by 3

x² + 4x - 3 = 0

add 3 to each side

x² + 4x = 3

divide 4 in half and square it; add it to each side of equation

x² + 4x + 4 = 3 + 4

(x + 2)² = 7

x + 2 = [tex]\sqrt{7}[/tex]

x = -2 ± [tex]\sqrt{7}[/tex]

Answer:

The cost of the t-shirt would be $19.20 with a 20% discount and the amount discounted is $4.80

Step-by-step explanation:

24*0.8 = $19.20

Answer:

Step-by-step explanation:

The discount is:

price × discount

We can substitute the discount of 20% for 0.2 and multiply to find the amount of money taken away which gives us the remaining amount or the amount you pay.

$19.20

So, to find area of triangle we have a formula :

[tex] \large \underline{\boxed{\bf{Area_{(triangle)} = \dfrac{1}{2} \times b \times h}}}[/tex]

[tex] \tt : \implies Area = \dfrac{1}{2} \times 8 \: cm \times 4 \: cm[/tex]

[tex] \tt : \implies Area = \dfrac{1}{2} \times 32 \: cm^2[/tex]

[tex] \tt : \implies Area = \cancel{\dfrac{32}{2}} \: cm^2[/tex]

[tex] \tt : \implies Area = 16 \: cm^2[/tex]

Hence, area of given triangle is 16 cm².

Answer:

(2x+2y+7)(x+y+7)

Step-by-step explanation:

I suspect this is what you are expected to do.

Define z=x+y
