it's D since you're trying to find the slope/ cost per Issue you divide 63/18 which simplifies to 7/2 and as a decimal gives you 3.50 which is the number of dollars per issue.

Step-by-step explanation:

let the price be x before increased.

After it is increased then it becomes 1.03x

i.e. 1.03x= 720

x=699.03 which is the price after it is increased.

The question is an illustration of percentage increase, and the price before the increase is £699

The given parameters are:

Initial = x

Rate = 3%

New price = £720

The equation of the initial price is:

x * (1 + rate) = New price

So, we have:

x * (1 + 3%) = 720

Evaluate the sum

x * 1.03 = 720

Divide both sides by 1.03

x = 699

Hence, the price before the increase is £699

Add 4 to both sides

-104 + 4 = -2(1 + 7x)

Simplify -104 + 4 to -100

-100 = -2(1 + 7x)

Divide both sides by -2

-100/-2 = 1 + 7x

Two negatives make a positive

100/2 = 1 + 7x

Simplify 100/2 to 50

50 = 1 + 7x

Subtract 1 from both sides

50 - 1 = 7x

Simplify 50 - 1 to 49

49 = 7x

Divide both sides by 7

49/7 = x

Simplify 49/7 to 7

Switch sides

Answer: x = 7

Answer:

(-11, - 9)

Step-by-step explanation:

Given the 2 equations

a - 3b = 16 → (1)

a = b - 2 → (2)

Substitute a = b - 2 into (1)

b - 2 - 3b = 16

- 2b - 2 = 16 ( add 2 to both sides )

- 2b = 18 ( divide both sides by - 2 )

b = - 9

Substitute b = - 9 into (2) for the corresponding value of a

a = - 9 - 2 = - 11

Solution is (- 11, - 9)

Answer:

x = 12

Step-by-step explanation:

The 2 given angles form a straight angle and are supplementary, thus

10x - 20 + 6x + 8 = 180

16x - 12 = 180 ( add 12 to both sides )

16x = 192 ( divide both sides by 16 )

x = 12

Step-by-step explanation:

To get the answer just use the numbers from the table which you have stated and you are right, you do get a long decimal.

5.69*10^26 / 6.42 * 10^23 = 886.29

which rounds to 886

Answer:

y = 6

Step-by-step explanation:

⇒ 17 y + 2 = 5 y + 74

→ ( - 5 y from both sides )

⇒ 12 y + 2 = 74

→ ( -2 from both sides )

⇒ 12 y = 72

( ÷ by 12 on both sides )

⇒ y = 6

Answer:

y = 6

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    17*y+2-(5*y+74)=0

   Pull out like factors :

  12y - 72  =   12 • (y - 6)

Solve :    12   =  0

Add  6  to both sides of the equation :

                     y = 6

D. 18+36y

Step-by-step explanation:

Because you would simply multiply each of the numbers in the parenthesis by the number outside, to get D.

Answer:

D. 18 + 36y

Step-by-step explanation:

Distributive property

The multiplication of a number by a sum is equal to the sum of the multiplications of that number for each of the addends.

6(3 + 6y) = (6)(3) + (6)(6y)= 18 + 36y

Answer:

16

Step-by-step explanation:

to find the range, you have to subtract the smallest number from the biggest number.

In this case 7-(-9)

7-(-9)=16

range=16

Answer:

16

Step-by-step explanation:

The range is the difference between the greatest number and the least number.

The greatest number here is 7.

The least number here is -9

Now, Subtract the least number from the greatest number:

7 - (-9) = 16

Hence the range is 16.

Answer:

x = 8√5

Step-by-step explanation:

The large triangle is divided into two smaller ones.  The right one has one leg of length 8, one leg of length x/2, and hypotenuse of length √80.

Appling the Pythagorean Theorem, we can find x:

8² + (x/2)² = (√80)²,

or:                              x^2

64 + x^2/4 = 80, or  ------- = 80

                                    4

Then x^2 = 320 = 64*5.  Taking the square root of both sides, we get:

x = 8√5

Answer:

The values of y is -4 and 6

Step-by-step explanation:

Solve by factoring y^2 -2y=24

We need to factorize the term y^2 -2y=24.

Rearranging:

y^2 - 2y -24 =0

For factorizing we need to break the middle term such that their sum is equal to -2y and product is equal to -24y^2

We know, -6y*+4y = 24y^2 and -6y + 4y = -2y

y^2 -6y +4y -24 =0

y(y-6) +4(y-6) = 0

(y+4)(y-6)=0

Now, y+4 =0 and y-6 =0

Finding value of y,

y = -4 and y =6

So, the values of y is -4 and 6

Answer:

y = (-3/7)x + 9 ( -1.5x − 3.5y = -31.5)

Step-by-step explanation:

Normally, there's a list of possible answers associated to this question, and the answer is usually in the form of  -1.5x − 3.5y = -31.5 (equivalent to  y = (-3/7)x + 9)

You forgot to provide the reference image which is essential to answer the question, but I managed to find it... and attach it to my answer.

In the given equation for AB, if we place the y term on the left and x term on the right, we see the slope of that line is 7/3 (y = (7x - 21.5)/3 ==> 7/3x).

We see on the image that the line PQ is perpendicular to AB.  That means that its slope is -3/7.

So, we have a slope  of -3/7 and we know it passes through point P (7,6), let's see if we can find the missing term.

y = (-3/7) x + b

6 = (-3/7) 7 + b

6 = -3 + b

b = 9

So the equation of the line forming the street PQ is y = (-3/7)x + 9

Answer:

2/3

Step-by-step explanation:

To be able to find what the total fraction of bagels eaten, the fractions need to have common denominators. To do this, you multiply 1/4 by 3 in both the numerator and the denominator. Now that the two fractions have the same denominator, you can add the fraction's numerator to get the total fraction, 8/12. However, 8/12 can be simplified more, so you divide by 4 and end up with 2/3.

Since we are given with the three sides of the triangle and asked to determine the angle, we can use the cosine law.

                              b² = a² + c² - 2ac(cosB)

Substituting the known values,

                         (1.8)² = (2.4)² + (1.6)² - 2(2.4)(1.6)(cosB)

The value of B from the equation is 48.6°.

Answer:

B = 60.6 degree

Step-by-step explanation:

Side AB, c = 1.2 miles

Side BC, a = 1.8 miles

Side CA, b = 1.6 miles

Use Cosine rule to find the angle B.

[tex]Cos B = \frac{a^{2}+c^{2}-b^{2}}{2ac}[/tex]

Putting the values of a, b and c

[tex]Cos B = \frac{1.8^{2}+1.2^{2}-1.6^{2}}{2\times 1.8\times 1.2}[/tex]

[tex]Cos B = \frac{3.24+1.44-2.56}{4.32}[/tex]

[tex]Cos B = 0.491[/tex]

B = 60.6 degree

A triangle is equal to 180.

5²+6²=30²

25+36=900

61=900

No solution

Answer:

No; it cannot form a right triangle

Step-by-step explanation:

Use the Pythagorean theorem.

5 squared + 6 squared ≠ 30 squared

25 + 36 ≠ 90000

61 ≠ 90000

Also, note that that the sum of the two shorter lengths have to be greater than the longer length to form any kind of triangle.

Answer:

x = 6 and y =4

Step-by-step explanation:

It is given that,system of equations 3x+7y=46 and -3x-8x=-50

To find the solution

Let  3x + 7y = 46 --------(1)

-3x-8x=-50   -------(2)

eq(1) + eq(2)

3x + 7y = 46

-3x - 8x = -50

        -y = -4

y = 4

(1) ⇒  3x + 7y = 46

3x + 7*4 = 46

3x= 46 - 28

3x = 18

x = 18/3 =6

Therefore x = 6 and y = 4
