Step-by-step explanation:
Disagree.
If each shirt is originally x dollars, then the new price is 0.8x. So the total cost is 1.6x, down from the original 2x.
So the discount is (2x − 1.6x) / 2x × 100% = 20%.

Answer:
the three vertices are (1, 1), (2, 0), (-1, -3).
The vertices of the triangles are the coordinates of the point of
intersection of the graph of the equation of the three lines.
Correct response:
The coordinates of the three vertices of the triangles are;
E. [tex]\underline{(2, 0), \ (1, -1), \ and \ (-1, -3)}[/tex]
How are the coordinates of the vertices obtained?The equation of the given lines are;
y = -x + 2, y = 2·x - 1, y = x - 2
The point of the intersection of the two lines, gives the vertices, and are
the solution of the two linear equations of the lines.
At the points where the lines intersect, we have;
-x + 2 = 2·x - 1
Which gives;
3·x = 3
x = 1
y = -1 + 2 = -1
A vertex is at the point (1, -1)
The coordinate of the second vertex is given as follows;
2·x - 1 = x - 2
2·x - x = -2 + 1 = -1
x = -1
y = -1 - 2 = -3
The second vertex is; (-1, -3)
The coordinates of the third vertex is given as follows;
-x + 2 = x - 2
2·x = 4
x = 2
y = 2 - 2 = 0
Which gives the point; (2, 0)
The three vertices are; E. (2, 0), (1, -1), and (-1, -3)Learn more about linear equations here:

A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 3 cups of ingredient A. How many cups of ingredient B do you need?
Answer:
8.4cups
Step-by-step explanation:
Given:
recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B.
By using the ratio of both ingredients
Let X= amount of ingredient A in cups
Let Y= amount of ingredient B in cups
We can interpret like this
(X/Y) = (1/2 cup)/(1 2/5 cups)
1 2/5 cups = 7/5 cups
(X/Y) = (1/2)/(7/5)
(7/5)X= (1/2)Y
We can find the value of Y
Y= 2*(7/5)X
Y = (14/5)X
You use 3 cups of ingredient A. Then X= 3cups, then Y=
Y = (14/5)× 3
Y=8.4cups
There are 8.4cups cups of ingredient B do you needed

Hernando ate StartFraction 2 Over 8 EndFraction of a pizza for a dinner. He gave his 6 friends the rest of the pizza and told them to share it equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below. StartFraction 6 Over 8 EndFraction divided by 6 = StartFraction (6 divided by 6) Over 8 EndFraction = one-eighth He concluded that each person received One-eighth of the whole pizza. Are Hernando's calculations correct? Explain why or why not. Yes, they are correct. Hernando divided 6 by 6. Yes, they are correct. Hernando divided Two-eighths by 6. No, they are not correct. Hernando should have multiplied by 6, not divided by 6. No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer:
Step-by-step explanation:
Hernando = 2/8
His 6 friends = 6/8
Total pizza = 2/8 + 6/8
= 8/8
Hernando's calculation
6/8 ÷ 6
= (6÷6) / 8
= 1/8
Correct calculation
6/8 ÷ 6
= 6 / 8 × 1/6
= (6 × 1) / (8*6)
= 6/48
= 1/8.
Therefore, Yes, they are correct. Hernando divided 6 by 6.

A truck can be rented from Company A for $130 a day plus $0.60 per mile. Company B charges $70 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
200 miles
Step-by-step explanation:
Let's say that our variable is x, where x equals the amount of miles
Company A: a(x)=0.6x+130
Company B: b(x)=0.9x+70
For the first equation, you are charged 130 dollars, in addition to the 0.60 cents that you are charged per mile.
For the second equation, you are charged 70 dollars, in addition to the 0.90 cents that you are charged per mile.
You want to find how many miles it takes to make the two equations equal:
0.6x+130 = 0.9x+70 (Set them equal to each other because you are trying to find when the miles are equal and the cost is equal)
130=0.3x+70 (Subtract 0.6x from both sides)
60=0.3x (Subtract 70 from both sides)
x=200 (Divide both sides by 0.3 to find x)
Remember that x is the amount of miles, so, Company A and B would charge the same if you drove 200 miles.
Answer:I believe it’s 200 miles
Step-by-step explanation: let x represent the mileage you are trying to find and set the two equations equal to one another to find the mileage and which the rental cost would be the same.
130 + 0.60x = 70 + 0.90x
130-70 = 0.90x - 0.60x
60 = 0.30x
X= 60/0.03
X= 200 miles
-0.64x+0.44x=5.8 solve for x
Answer:
x=-29
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−0.64x+0.44x=5.8
(−0.64x+0.44x)=5.8(Combine Like Terms)
−0.2x=5.8
−0.2x=5.8
Step 2: Divide both sides by -0.2.
-0.2x/-0.2=5.8/-0.2
x=-29

Mike is on vacation and decides to rent a bike for part of the week. The rental cost is represented by the function c(d) = 25+20d, where is the number of days of use and c(d) is the total cost for d days of use. How much does the bike cost Mike if he uses it for 4 days?
Answer:
Cost for 4 days is 105
Step-by-step explanation:
To get the cost for 4 days, we simply substitute 4 for the value of d in the equation
Thus, we have
c(4) = 25 + 4(20)
C(4) = 25 + 80
C(4) = 105
