Answer:
25
Step-by-step explanation:
19 *100/76
Number into 100 by percentage
By asking the question this way, you can create an equation from the question:
19 is 76% of what number?
19 = 0.76 • x
And to solve this equation, you divide both sides by 0.76 to find
25 = x
Yes, it’s the same answer someone else provided. Approaching the percentage problems by setting up the format
A is P percent of B
can help you have a consistent approach to solving.

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

Oh(x) = 22x + 3
X E all real numbers
Oh(x) = 22x – 3 x € all real numbers
Answers
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.
What is a function?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)

The sum of 4 times a number and - 7, added to 9 times the number
Answers
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.
What is an expression?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.

A nut store normally sells cashews for $4.00 per pound and peanuts for $1.50 per pound. But at the end of the month the peanuts had not sold well, so, in order to sell 80 pounds of peanuts, the manager decided to mix the 80 pounds of peanuts with some cashews and sell the mixture for $2.00 per pound. How many pounds of cashews should be mixed with the peanuts to ensure no change in the revenue?
The manager should mix _ pounds of cashews with the peanuts.
Answers
9514 1404 393
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.

The Hayes family and the Butler family each used their sprinklers last summer. The water output rate for the
Hayes family's sprinkler was 20 L per hour. The water output rate for the Butler family's sprinkler was 15 L
per hour. The families used their sprinklers for a combined total of 50 hours, resulting in a total water output
of 825 L. How long was each sprinkler used?
Answers
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

Find the length of PQ if PQ = QR
Answers
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).

Mike can bind 109 flowers per hour, John can bind 116 flowers
per hour. If they work together for 5 hours, how many flowers
can they bind?
flowers
Answers
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
Write an equation for each sentence then solve. The sum of two consecutive even numbers is thirty-four. What are the numbers? I just need to know the equation
Answers
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 ...!
Verefication :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]
