Complete question :
Merlin wants to make more money selling fake beards this month than he did last month. All black beards in his shop cost the same amount of money, and all red beards in his shop cost $25. Let B represent the number of black beards and R represent the number of red beards that Merlin can sell to make more money than he made last month. 20B+25R > 350 According to the inequality, how much money did Merlin make last month, and how much does each black beard cost?
Answer:
1.) > 350
2.) $20
Step-by-step explanation:
Number of black beard = B
Number red beard = R
Cost of red beard = 25
Last month inequality :
20B+25R > 350
Amount Merlin made last month :
Revenue from both red and black Bearf, Hence amount realized last year greater than 350
Cost per black beard is the Coefficient of B which is 20

y - 200+ 0.50x
y = 50 + 0.30x
Consider the data shown on the graph.
• The y-intercept represents the base price of $ drag and drop answer here for airfare from NYC
• The slope represent a cost of drag and drop answer here cents per mile traveled.
• If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be drag and drop answer here
• If the cost per mile changed to 50 cents, the new equation would be drag and drop answer here
Answer:
Step-by-step explanation:
THE ANSWER IS 200 , 30, Y=50+0.30X, Y=200+ 0.50X
The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
EXPLANATION
The equation given can be express as
y = 0.25x + 50
y = 0.30x + 40
Since, both equations are functions
Equate the two functions together
0.25x + 50 = 0.30x + 40
Collect the like terms
0.25x - 0.30x = 40 - 50
x(0.25 - 0.30) =-10
x(-0.5) = -10
-0.5x = -10
Divide both sides by -0.5
-0.5x / -0.5 = -10/-0.5
x = 10/0.5
x = 20
When collecting the like terms, we isolate values with the same variables from values with a different variables.
If a positive sign crosses an equality sign it automatically becomes a negative sign and if a negative sign crosses an equality operator it automatically becomes a positive sign.
Hence, The solution is, x = 20, is the solution of Y=0.25x +50=0.30x+ 40.

Ann and Betty shared a sum of money in the ratio 2:3. If Ann received $120,what was the amount of money shared?
Answer:
$420
Step-by-step explanation:
Given data
GIven ratio= 2:3
The total ratio= 2+5= 7
Ann's share= $120
Let us apply the part to all approach
let the total amount be x
so for Ann
2/7= 120/x
cross multiply
2x= 120*7
2x= 840
divide both sides by 2
x= 840/2
x= 420
Hence the amount shared is $420
A recent survey asked 100 randomly selected adult Americans if they thought that women should be allowed to go into combat situations. Here are the results: Gender Yes No Male 32 18 Female 16 34 Here are the results: the probability that a randomly selected subject in the study is male or answered "no" is
Answer:
26/25
Step-by-step explanation:
total number of men/ total sample + total number of people that answered no / total sample
total male = 32 + 18 = 50
total sample = 100
total no 18 + 34 = 52
50/ 100 + 52/100 = 102/100 = 52/50 = 26/25
The perimeter of an equilateral triangle is 63 inches. If the length of each side is (4x-3), find the value of x. Equilateral means all sides are equal.
Answer:
Step-by-step explanation:
3*(4x - 3) = 63 Divide both sides by 3
4x - 3 = 63/3
4x - 3 = 21 Add 3 to both sides
4x = 21 + 3
4x = 24 Divide by 4 on both sides
4x/4 = 24/4
x = 6
Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)

Write the number in 2 equivalent forms as a fraction, decimal, or percent.0.40
Answer:
2/5 or 40%
Step-by-step explanation:
.40 is 40 hundredths or 40/100
40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5
Percentages are fractions out of 100 so 40/100 would be 40%.
