Answer:

The number is 20

Step-by-step explanation:

Let the number be x

5(x - 9) = 2x + 15

5x - 45 = 2x + 15

5x - 2x = 15 + 45

3x = 60

x = 60/3

x = 20

Answer:

The number is 20

Step-by-step explanation:

Five times the difference of a number and 9

5(x-9)

is equal to twice the number plus 15.

=2x+15

5(x-9)=2x+15

Distribute

5x-45 = 2x+15

Subtract 2x from each side

5x-45-2x = 2x+15-2x

3x-45 = 15

Add 45 to each side

3x-45+45 =15+45

3x = 60

Divide by 3

3x/3 = 60/3

x =20

Answer:

12. -11

13. 2

Step-by-step explanation:

12. First recall the order of operations (BEDMAS): Brackets, Exponents, Division, Multiplication, Addition, Subtraction

For question 12 there is a division and its priority is before other operations in the equation so you must divide 16/-2 first which gives you -8.

From there because addition and subtraction is on the same level of order, you would do the question straight as it is shown (but replace 16/-2 with -8.

Your new equation is -10-8+7 = -11

13. follow the same as above using BEDMAS. It may help to look at it with additional brackets: ((-68)/(-4)) + ((5 x (-3))

Division and multiplication is on the same level in BEDMAS so first divide -68/-4 = 17

Second multiply 5 x -3 = -15

Now you can combine the two answers using addition: 17 + (-15) = 2

The range of the function y = x2 is all real numbers, y, such that y ≥ 0.

Answer:

I wish I could but I think its c

    Function defining the cost of buying and shipping will be represented by,

C(x) = ax + b

Here, a = price of one jar, b = shipping charges and x is the price of jar preserve

     Function representing the cost C for buying and shipping 'x' jars of preserves will be,

C = $(9.15x + 3.75)

  It's given in the question,

Let the number of jars purchased = x

Therefore, charges for 'x' jars = $8.50x

So the shipping and handling charges for shipping 'x' jars = $(3.75 + 0.65x)

Therefore, total charges for shipping and preserving 'x' jars = $(3.75 + 0.65x) + $8.50x

        Therefore, function representing the cost C for buying and shipping 'x' jars of preserves will be,

C = $(3.75 + 0.65x) + $8.50x

C = $(9.15x + 3.75)

Answer:

Vertical angles are nonadjacent angles.

Step-by-step explanation:

got it right on a test

The correct answer is vertical angles are nonadjacent angles.

Vertical angles are angles that are opposite of each other when two lines cross. Vertical angles are. congruent, meaning that they have the same angle measure.

When two lines cross, the angles oppose each other. They're constantly on the same level. A° and b° are vertical angles in this example. NOT up/down, "vertical" refers to the vertex (where they cross). Vertically opposed angles is another name for them.Vertical angles are nonadjacent angles.

Answer:

7

Step-by-step explanation:

There are a few different methods of which you can solve this problem:

Method #1

Lets break this shape into 3 parts, First the large square, then the rectangle and then the triangle. First we can find the area of the square by multiplying 2 by 2 which will be 4,

Now lets work on the rectangle, Since we cut the square out of this shape, We are left with a rectangle of which the sides are 2 and 1, now you can multiply and get 2.

We are left with the triangle, This triangle has a side of 1, and 2 , which is 2, but we have to divide by 2, which is one.

Now add all of them together 4+2+1 = 7.

Method #2

You can multiply 4 by 2 then subtract the area of the triangle.

Alright, 2X4 is 8, now the are of a triangle is BH/2 lets substitute  Base = 2,

Height = 1, 2*1/2 = 2/2 = 1

8-1 = 7

     We can solve this problem by using the fact that speed of typing is defined as the words typed in unit time.

Dana will type [tex]2.6\times 10^5[/tex] words in 48.15 hours.

It's given in the question,

Since, 1 minute = [tex]\frac{1}{60}[/tex] hours

Therefore, number of words she can type = [tex]\frac{90}{\frac{1}{60}}[/tex]

                                                                      = 90×60

                                                                      = 5400 words per hour

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= [tex]5400\times x[/tex]

Therefore, [tex]5400\times x =2.6\times 10^5[/tex]

[tex]5400x=260000[/tex]

[tex]x=\frac{260000}{5400}[/tex]

[tex]x=48.15[/tex] hours

               Therefore, Dana types [tex]2.6\times 10^5[/tex] words in 48.15 hours.
