Given parameters:
Cost per pound of Arabica coffee = $28 per pound
Cost of Robusta coffee = $8.75
Given number of pounds of Robusta Coffee = 3 pounds
Total cost of blend per pound = $15.50
Unknown:
Number of pounds of Arabica coffee = ?
Solution:
Let the number of pounds of Arabica coffee = A;
We have to interpret this problem algebraically and solve;
28A + 8.75(3) = 15.5(A + 3)
Now solve the expression above for A;
28A + 26.25 = 15.5A + 46.5
28A - 15.5A = 46.5 - 26.25
12.5A = 20.25
A = 1.62
Number of pounds of Arabica Coffee is 1.62 pound
Answer:
1.62 pound

What is the slope of the line that passes through the
points (-4, 10) and (2, 22).
Answer:
2
Step-by-step explanation:
slope= (y2-y1)/x2-x1)
= (22-10)/(2--4)
= 12/(2+4)
= 12/6

Reduce: -8/40 (pls answer)
Answer:
-1/5
Step-by-step explanation:
The first step you do is to find what are the numbers GCF which in this case it is 8
which now with the GCF you divide -8 by 8 and 40 by 8
which -8 divided by 8 is -1
and 40 divided by 8 is 5
so the fraction is -[tex]\frac{1}{5}[/tex]

Given that f(x)=2x+1 and g(x)=3x-1/2 find g(f(3))
1. 5
2. 7
3. 9
4. 10
Answer:
7
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
10
Step-by-step explanation:
You must substitute the 3 for the x in f(x) = 2x+1 first
f(x) = 7
Then substitute the 7 for the x in g(x) = (3x - 1)/2
g(x) = 10

The points on a section of an exam are given by the function f(x), where x is the number of questions answered correctly in that section. If [tex]f(12)=18[/tex], then a test-taker receives 18 points for answering _____ questions in the sections correctly.
Answer:
Step-by-step explanation:
X=5?
Answer:
The answer is 12
Step-by-step explanation:
In the beginning, it says f(x) where x is the number of questions answered correctly in that section. So whatever replaces x is your answer. In this case, it is 12.
Which of the following tables represents the rule, y equals seven less than four times a number?
Answer:
the second table.
Step-by-step explanation:
I used process of elimination to determine which one fits.
here's how I know I'm correct:the rule is, y = 4x - 7
if you put in the numbers from table 2
-3 = 4(1) - 7
-3 = 4-7
-3 = -3
13 = 4(5) - 7
13 = 20 - 7
13 = 13
How does the side length of the square relate to the square root?
Answer:
The sides can be found by taking the square root of the area. , where = side.
Step-by-step explanation:
Answer:
the area of any quadrilateral can be determined by multiplying the length of its Base by its height. since we know the shape here is square we know that all sides are of equal length. from this we can work backwards by taking the square root of the area to find the length of one side.
Express the statement "A rectangular field with an area of 120m' has it length 12mn longer than the width" as quadratic equation.
Answer:
The quadratic equation is x^2 -12x -120 = 0
where x represents the length of the field
Step-by-step explanation:
We want to make an expression in terms of a quadratic equation;
Let the length of the field be x mm , then the width will be (x-12) mm
Mathematically , the area of the field will be L * B
Thus;
x * (x-12) = 120
That gives;
x^2 -12x = 120
x^2 -12x -120 = 0

y= 3/2x -8
Step-by-step explanation:
y=mx+b
Mr. and Mrs. Wagner are getting ready to drive across the USA from Philadelphia, PA to Los Angeles, CA in five days. The distance is approximately 3,000 miles. The average price of gasoline is about $2.10 per gallon. They plan to stay in a hotel for four nights and budget the cost of meals be about $45 per day per person.
Answer:
(a) $ 84.
Step-by-step explanation:
Given that, the distance between the PA to CA = 3000 miles.
Time of travel, t = 5 days.
The average price of gasoline, r = $ 2.10/ gallon
Cost of meal for one person, c = $ 45/ day
Total number of persons, n = 2 (Mr. and Mrs. Wagner)
(a) The average of van = 75 mpg.
So, to cover 75 miles, the amount of gasoline required = 1 gallon
By using the elementary method, the amount of gasoline required to cover 1 mile = 1/75 gallons.
So, the amount of gasoline required to cover 3000 miles
= (1/75)x 3000= 40 gallons.
Now, cost for gasoline = 40 x 2.10=$84
Hence, the total cost of the gas for the trip is $84.
