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

Adding cheese to a McDonald's Quarter Pounder increases the fat content from 21 g to 30 g. What percent does the fat content increase
Answer: 42.9%
Step-by-step explanation:
The percentage increase of the fat content will be calculated as:
= Fat increase / Previous fat content × 100
= (30 - 21) / 21 × 100.
= 9/21 × 100
= 42.9%

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.
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.
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]
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]

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.

Jeremy lost his dog, and wants to make some signs to put up in the neighborhood. The cost to make 8 paper signs and 2 laminated signs is $12.00. The cost to make 10 paper signs and 10 laminated signs is $30.00. What is the cost of 1 laminated sign?
Answer:
cost to make paper signs = $1
cost to make laminated signs = $2
Step-by-step explanation:
Let
x = cost to make paper signs
y = cost to make laminated signs
8x + 2y = 12 (1)
10x + 10y = 30 (2)
Multiply (1) by 5
40x + 10y = 60 (3)
10x + 10y = 30 (2)
Subtract (2) from (3) to solve for x
40x - 10x = 60 - 30
30x = 30
x = 30/30
x = $1
Substitute x = 1 into (1)
8x + 2y = 12
8(1) + 2y = 12
8 + 2y = 12
2y = 12 - 8
2y = 4
y = 4/2
y = $2
cost to make paper signs = $1
cost to make laminated signs = $2

Answer:
x = 4
Step-by-step explanation:
4x + 2 = 5x -6
4x -5x = 6-2
-x = 4
x = 4
Answer:
x=8
Step-by-step explanation:
4x+2=5x-6 subtract both sides by 4x
2=5x-4x-6 simplify
2=x-6 add 6 to both sides
6+2=x simplify
8=x
