Store A sells boxes of rice for $2.50 each.
Store B sells rice by the pound for $2.50 per pound.
The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.
The domain of c(n) = 2.5n is all the real numbers.
For each store, drag the restriction needed on values of n for c(n) to model each situation.

When a number is decreased by 54%, the result is 28. What is the original number to the nearest tenth?
Answers
Answer:
x=60.9
Step-by-step explanation:
Let x represent the number
x - 54%x = 28
x - 0.54x = 28
0.46x = 28
Divide both sides by 0.46
x = 28/0.46
x = 60.86
x = 60.9

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
In the figure, lines a and b are parallel.
Now, By definition of alternate and corresponding angles, we get;
⇒ m ∠1 = m ∠ 5
⇒ m ∠6 = 75°
And, By definition of linear pair of parallel lines,
⇒ m ∠2 + m ∠5 = 180°
Thus, All the correct statements that are true,
⇒ m ∠1 = m ∠ 5
⇒ m ∠2 + m ∠5 = 180°
⇒ m ∠6 = 75°

Write and solve an equation that can be used to find x, in the figure below:
Answers
Answer: x=40
Step-by-step explanation:
so you would add the two angles you already know.
30+63=93
The sum of the angles of a triangle is always 180°. Knowing this, you can do
180-93=87
so you know the third angle is 87°
plug this into the equation: 2x+7
2x+7=87
subtract both sides by 7
2x=80
divide by two
x=40
1. Add the 2 angles you already know.
30 + 63 = 93
2. The sum of all angles in a triangle is always 180°
180 - 93 = 87
3. third angle is 87°
2x + 7 = 87
4. Subtract BOTH sides by 7
2x = 80
5. Divide by 2
X = 40

Answer:
25. y=2x+1
26. $13
Step-by-step explanation:
25. 2x is the cost each day or the x, and the 1 is the initial fee, I found this because it said one day costs $3 and if I know that one days fee is $2 then I know that the y intercept or the price it starts at also known as a fee is $1. This is also backed up in the 4 day statement saying that 4 days is 9 dollars. I can do 9-1 to take away the fee and 8/2=4 so it is correct.
26. Since I already have the equation I can just plug in the vales and solve. y=2x+1, x=2 or the daily cost so 12+ (the fee) 12+1=13 so $13.
good luck, and have a great day. :)

Answers
Answer:5. is 500%
Step-by-step explanation:
Explanation:
For #4, the coin is equal to $2 1/2, or $2.50. Since the question is asking the worth of each coin as a percentage of $1, $2.50 will be a percentage greater than 100%. $2.50 is 2.5x $1, so if $1 is seen as 100% in this problem, we can do 100 x 2.5. This is how you get the answer of 250%
You use the same method for question 5, except $5 is 5x $1, so we can do 100 x 5 to get 500%

the points (z,0) and (4,6) fall on a line with a slope of 6. What is the value of z?
If its not right im gonna report you
Answers
Answer:
z = 3
Step-by-step explanation:
First we want to find out how they found the slope of the line. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)
Plug in these values:
(6 - 0)/ (4 - z)
Simplify the parentheses.
= (6) / (4 - z)
Simplify the fraction.
= 6/(4 - z)
it is given that 6 is your slope. So let's add 6 to the left side of the equal sign.
6 = 6 / (4 - z)
To solve for z, we need to multiply both sides by (4 - z)
(4 - z)6 = 6
Now, divide both sides by 6 to isolate the expression of (4 - z)
4 - z = 1
Add z to both sides so it becomes positive.
4 = z + 1
Subtract 1 from both sides to isolate z.
3 = z
This is your answer.
Let's check it by plugging it back into the slope formula.
(6 - 0)/ (4 - z)
(6 - 0)/ (4 - 3)
= 6/1
= 6
Your answer is correct.
Hope this helps!
