Subsitute the x and y with the numbers

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:

23y-8

Step-by-step explanation:

First add together all of the terms that are next to a variable:

2y+10y+5y+6y=23y

Then add together all of the integers that are alone:

-9+10+(-7)+(-2)= -8

Add the two terms together and you get:

23y-8

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

Answer: 7.83

Step-by-step explanation:

83 over 100 is the same as 83 divided by 100. 83/100 = 0.83

7 + 0.83 = 7.83

Answer:

7.83

Step-by-step explanation:

7 is the whole number

83 is the number that goes to the right of the decimal point

the 100(denominator) shows which place value it should be in, in the decimals place.

    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:

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

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.

Referring to the figure, does the triangle shown have

a. yes

b. no

     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.
