Let the first even number be 'x' & the second even number be (x + 2)

According to the Question,

⇒x + (x + 2) = 34

⇒x + x + 2 = 34

⇒2x + 2 = 34

⇒2x = 34 - 2

⇒2x = 32

⇒x = 32/2

⇒x = 16

⇒First even number = x = 16

⇒Second even number = (x + 2) = 16 + 2 = 18

∴ The two consecutive even numbers are 16 & 18 ...!

As, In our Question it was given that "The sum of two consecutive even numbers is thirty-four". So, as we got our two consecutive even numbers as 16 & 18 ... By this, we can say that these both even numbers should be equals to 34, i.e., 16 + 18 = 34. Hence, The equation which we formed is correct ...!

The equation:

[tex]x + ( x+ 2) = 34[/tex]

The solution:

[tex]x + x + 2 = 34[/tex]

[tex]2x + 2 = 34[/tex]

[tex]2x = 34 - 2[/tex]

[tex]2x = 32[/tex]

[tex]x = \frac{32}{2} [/tex]

[tex]x = 16[/tex]

The numbers would be 16 and 18.

Answer:

  f(x) = 19.8x +1080.2

Step-by-step explanation:

The given values form an arithmetic sequence with first term (a1) = 1100 and common difference (d) = (1119.80-1100) = 19.80.

The generic term of an arithmetic sequence is ...

  an = a1 +d(n -1)

  an = 1100 +19.8(n -1) = 1080.2 +19.8n

Expressed as a function of x, this is ...

  f(x) = 19.8x +1080.2

Hello!

We know that mike can bind 109 flowers per hour.

Lets create an equation to remember this.

Mikes equation:

109x = y

<x is representing per hour in this math problem>

We know that John can bind 116 flowers per hour, here is his equation.

Johns equation:

116x = y

Question: If they work together for 5 hours, how many flowers  can they bind?

First, plug in the number five in both equations.

Second, solve the equation by multiplying.

Mikes:

109(5) = y

109 times 5 is 545

y = 545

Johns:

116(5) = y

116 times 5 is 580

y = 580

We want to know how many flowers can they bind if they work together.

This means we need to add the answers of the equations from both mike's and john's together.

545 + 580 = 1,125

The answer is 1,125

Answer:

3,200 sq ft

Step-by-step explanation:

20 X 2ft = 40ft

40 X 2ft = 80ft

40ft X 80ft = 3,200 sq ft

The number of square feet in the backyard will be 3,200 square feet

Since each step is being  about 2 feet, which means the length will be :

20 steps

Length=20×2

Length=40 feet

40 steps

Length=40×2

Length=80 feet

Now let calculate How many square feet is the backyard will

Square feet=40 feet×80 feet

Square feet=3,200 square feet

Inconclusion The number of square feet in the backyard will be 3,200 square feet

Answer: The Hayes family sprinkler was used 15 hrs and the Butler family sprinkler was used 35 hrs.

Step-by-step explanation:

Let the Hayes family sprinkler used = 50 - x hr.

Butler family sprinkler used = x hr.

20 (50 - x) + 15x = 825

1000 - 20x + 15x = 825

175 = 5x

5x = 175

x = 35

The Hayes family sprinkler was used 15 hrs and the Butler family sprinkler was used 35 hrs.

Answer:

13x – 7

Step-by-step explanation:

If "a number represents x", then:

The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.

(4x + -7) + 9x →

(4x + 9x) + -7 →

(13x) + -7 →

(13x) – 7 →

13x – 7.

The unknown number will be equal to 4.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that the sum of 4 times a number and - 7, added to 9 times the number is 45. The value of the unknown number will be calculated as below:-

The sum of 4 times a number and - 7, added to 9 times the number = (4x + -7) + 9x.

(4x + -7) + 9x = 45

(4x + 9x) + -7 = 45

(13x) + -7 = 45

(13x) – 7 = 45

13x – 7 = 45

13x = 45 + 7

13x = 52

x = 4

Therefore, the unknown number will be equal to 4.

The complete question is given below:-

The sum of 4 times a number and - 7, added to 9 times the number is 45. Calculate the value of an unknown number.

Answer: the answer is not C

Step-by-step explanation:

The function that represents the combined function is h(x) = 2x/(2x + 3).

where x ∈ all real numbers.

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 2x

g(x) = 2x + 3

Now,

h(x) = f(x) / g(x)

h(x) = 2x / (2x + 3)

Where x ∈ all real numbers

Thus,

The combined function is h(x) = 2x / (2x + 3)

Answer:

  20 pounds

Step-by-step explanation:

Often, mixture problems are worked by writing two equations: one for the total quantity of constituents in the mix, and one for the total price of the mix. When these equations are solved by substitution, the first step is to write one quantity in terms of the other.

You can save an equation and a step by using one variable for quantity. It usually works best to let the variable represent the highest-cost (or most concentrated) contributor. Here, that is the quantity the problem asks for, so ...

Let c represent the number of pounds of cashews needed to be mixed with the peanuts. Then the revenue from selling the mix is ...

  80($1.50) +c($4.00) = (80+c)($2.00)

  120 +4c = 160 +2c . . . . . divide by $, simplify

  2c = 40 . . . . . . . . . . . . . subtract 120+2c from both sides

  c = 20 . . . . . . . . . . . . . divide by 2

The manager should mix 20 pounds of cashews with the 80 pounds of peanuts.

Answer and Step-by-step explanation:

To find the length of PQ, we need to set the length of PQ equal to the length of QR (since in the question it tells us that PQ is equal to QR).

PQ = QR

x + 1 = 12

Solve for x.

Subtract 1 from both sides of the equation.

x + 1 - 1 = 12 - 1

x = 11

Now plug this number into the expression length for PQ.

11 + 1 = 12

The length of PQ is 12.

(you can also see that QR has a length of 12, so we can just say that PQ 12).
