Answer:
Salt
Step-by-step explanation:
At its peak, Ghana was chiefly bartering gold, ivory, and slaves for salt from Arabs and horses, cloth, swords, and books from North Africans and Europeans. As salt was worth its weight in gold, and gold was so abundant in the kingdom, Ghana achieved much of its wealth through trade with the Arabs.

2(x/8 + 3) = 7 + 1/4x what is x
Answer:
x1 = 2 -[tex]\sqrt{5}[/tex]
x2= 2 +[tex]\sqrt{5}[/tex]
Step-by-step explanation:
x/4 + 6 = 7 + 1/4x
(x^2 - 1)/4x = 1
x^2 - 1 = 4x
x^2 - 4x -1 = 0
x= (4+[tex]\sqrt{20}[/tex])/2 = 2 -[tex]\sqrt{5}[/tex]
x= 2 +[tex]\sqrt{5}[/tex]

if a system of linear equation has an infinite number of solutions, what do you know about the graph of the system?
a. the lines intersect at one point
b. the lines are parallel
c. the lines are the same
d. the lines cannot he graphed
Answer:
c. the lines are the same
Step-by-step explanation:
A system of linear equations has an infinite number of solutions because the lines are the same. The correct answer would be an option (C).
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
If a system of linear equations has an infinite number of solutions, it means that the equations are equivalent and represent the same line in the coordinate plane.
Therefore, the graphs of the two equations will be the same line, meaning that the lines are coincident. They won't intersect at one point, nor will they be parallel, as the definition of an infinite number of solutions is that they are the same line. And they can be graphed, as they represent a single line in the coordinate plane.
Hence, the correct answer would be option (C).

Answer:
2.85
Step-by-step explanation:
Amount Saved = $2.85 (answer). In other words, a 5% discount for a item with original price of $57 is equal to $2.85 (Amount Saved).
Step-by-step explanation:
I dont like giving the answers to math questions, but the way in which your suppose to answer this is by finding the original price before the discount. To do this, turn the percent into a decimal (for five percent, 0.5) and divide the original price. This number should give you the discounted price! hope this helps you!
A function is defined as follows:
IN THE SCREENSHOT
For which x-values is f(x) = 4? Select all that apply.
-2
1
2
13
Answer:
f(x) = 4 for the values 2 and -2.
Step-by-step explanation:
Given
y = { x+6 x < -2
x² -2 ≤ x ≤ 3
3x+1 x > 3 }
To determine
For which x-values is f(x) = 4
It is clear that:
The portion of the function f(x) = x² has the interval -2 ≤ x ≤ 3
Now, if we enter x = 2 or x = -2 in f(x) = x² from the interval -2 ≤ x ≤ 3 we get the output 4.
i.e.
at x = -2,
f(-2) = (-2)² = 4
also
at x = 2,
f(2) = (2)² = 4
Therefore, f(x) = 4 for the values 2 and -2.

3.5(2.25 + x) = 14
x = ?
Answer: x= 1.75
Step-by-step explanation:
3.5(2.25+x)= 14 *distribute 3.5 into parentheses*
(7.875+ 3.5x)=14 *subtract 7.875 from both sides*
3.5x= 6.125 *divide*
Your answer is 1.75.
In the equation a and b represent the price per night for a room in hotel a and hotel b respectively w week s
Answer:
A = $80
Step-by-step explanation:
A = 240 - 20w
B = 320 - 30w
Equate both equations
240 - 20w = 320 - 30w
Collect like terms
240 - 320 = -30w + 20w
-80 = -10w
Divide both sides by -10
w = -80/-10
w = 8
Substitute w into equation A
A = 240 - 20w
= 240 - 20(8)
= 240 - 160
= 80
A = $80

6: REDUCE to simplest term. 4/1 + 15/2
Answer:
[tex]\frac{4}{15}+\:\frac{1}{2}[/tex] in the simplest term is:
[tex]\frac{4}{15}+\frac{1}{2}=\frac{23}{30}[/tex]
Step-by-step explanation:
Given the expression
[tex]\frac{4}{15}+\:\frac{1}{2}[/tex]
Thus, solving to reduce to the simplest term
[tex]\frac{4}{15}+\frac{1}{2}[/tex]
LCM of 15, 2: 30
Adjusting fraction based on the LCM
so the expression becomes
[tex]\frac{4}{15}+\:\frac{1}{2}=\frac{8}{30}+\frac{15}{30}[/tex]
Apply the fraction rule: [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]
[tex]=\frac{8+15}{30}[/tex]
Add the numbers: 8+15 = 23
[tex]=\frac{23}{30}[/tex]
Therefore, [tex]\frac{4}{15}+\:\frac{1}{2}[/tex] in the simplest term is:
[tex]\frac{4}{15}+\frac{1}{2}=\frac{23}{30}[/tex]
