Answer:

41.5

23.5

Step-by-step explanation:

Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:

x + y = 65

The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:

x - y = -18

Now solve equation B for x to get the revised equation B:

x = -18 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 65

-18+y+y=65

-18 + 2y = 65

2y = 83

y = 41.5

Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:

x + y = 65

x + 41.5= 65

X = 23.5

DIfference : 23.5 - 41.5 = 18

Sum: 41.5 +23.5 = 65

Hence, The two number are 23.5 and 41.5

Answer:

a) [tex]a_{n}[/tex] = 13.8 + 0.2n

Step-by-step explanation:

Given :-

a = 14

d = 0.2

To Find :

[tex]a_{n}[/tex]

Solving :-

[tex]a_{n}[/tex] = a + (n - 1)d

[tex]a_{n}[/tex] = 14 + 0.2n - 0.2

[tex]a_{n}[/tex] = 0.2n + 13.8

Solution :-

a) [tex]a_{n}[/tex] = 13.8 + 0.2n

Which ways?

The side lengths that make the area of rectangles as modelled are -

{ 1 } - (x + 2)

{ 2 } - (x - 5)

{ 3 } - (x + 3)

{ 4 } - (x - 1)

A function is a elation between a dependent and independent variable.

Given is to identify the correct side lengths of the figures.

We can write the side lengths as -

{ 1 } - (x + 2)

{ 2 } - (x - 5)

{ 3 } - (x + 3)

{ 4 } - (x - 1)

Therefore, the side lengths that make the area of rectangles as modelled are -

{ 1 } - (x + 2)

{ 2 } - (x - 5)

{ 3 } - (x + 3)

{ 4 } - (x - 1)

Answer:

The custodian will be able to repaint 7 bookcases with the amount of paint.

Step-by-step explanation:

The custodian  has  5 1/4 gallons of  paint, to find the number of bookcases the custodian will be able to repaint with this amount of paint if each bookcase requires 3/4 gallons, then we will simply divide 5 1/4 by 3/4 to give  us the number.

But first we need to change 5 1/4 to improper fraction,

thus; 5 1/4 =  

5 1/4 ÷3/4   =   ÷

(We will want to change the division sign to multiplication, to do that, we will have to take the inverse of 3/4 which is 4/3 hence;

                   = ×

4 will cancel out 4 hence;

                    =

                    = 7

Therefore the custodian will be able to repaint 7 bookcases with the amount of paint.

Given :

Marvelous Meals charges $700 plus $35 per person. Posh Parties charges $425 plus $50 per person.

To Find :

Which company will cost less.

Solution :

Let, after x people Marvelous Meals charge less than Posh Parties :

So, 700 + 35x < 425 + 50x

275 < 15x

x > 18.33 i.e x > 18

Therefore, after 18 people Marvelous Meals charge less than Posh Parties.

Hence, this is the required solution.

Answer:

Subtract 3

Step-by-step explanation:

The first operation that should be done first in the expression 5x + 3 = 28 is subtracting 3 from both sides.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, 5x + 3 = 28.

The first operation that should be done first is subtracting 3 to both the side of the equation to separate the variable x and the constant term.

∴ 5x + 3 - 3 = 28 - 3.

5x = 25.

x = 5.

Step-by-step explanation:

Let age of Carlos is x. It is mentioned that the sum of age of Carlos and his mother is 47 years old. Age of Carlos is 23.

We need to find the equation that represents the sum of Carlos' age with his mother.

x+23 = 47 is the required equation.

Also, we can find the age of Carlos as :

x = 47 - 23

= 24 years
