POSSIBLE POINTS. 7 Two clothing stores are having a sale on all their dress shirts. Store A is charging $15 for each dress shirt. Store B is $18 for each shirt but giving customers a coupon for a $9 discount when they check out. Which of the following statements are true? There can be more than one correct answer.
Answer:
The statements are not provided, so i will answer in a general way.
Let's define the variable x as the number of dress shirts brought for some person.
In store A, each one costs $15.
Then the cost of x dress shirts will be:
A(x) = $15*x.
In store B, each one costs $18, but there is a coupon of $9, then we can write the cost in store B as:
B(x) = $18*x - $9.
Now we can find wich store will be cheaper for a given number x, by calculating the difference between A(x) and B(x).
D = A(x) - B(x)
If D is positive, means that B(x) is cheaper.
If D is negative, means that A(x) is cheaper.
If D is equal to zero, means that the cost is the same in both stores.
D = A(x) - B(x) = $15*x - $18*x + $9 = (-$3*x) + $9.
First, let's find for what value of x we have the same cost in both stores:
0 = (-$3*x) + $9.
$9/$3 = 3 = x.
Then for 3 dress shirts, the cost will be the same in each store.
Now, as the coefficient that multiplies x is negative, if we have x > 3, then D will be negative, and if x < 3, D will be positive.
then:
For x = 3, the cost is the same in both stores.
for x > 3, Store A is cheaper.
For x < 2, Store B is cheaper.

The length of a rectangle is 6 centimeters less than twice its width. The perimeter of the rectangle is 48 cm. What are the
of the rectangle?
Answer:
the length is 12 and the width is 9.
Step-by-step explanation:
The first step is always to assign letters to the variables. We can call length L and width W.
Since all units are in cm, unit conversion is unnecessary.
Next, set up some equations. L=2W-6 because of the first sentence of the problem. Length times width equals area, so L*W=108.
Now that there are two equations and two variables, the next step is to solve the system. I'm going to solve it by plugging in the right side of the first equation in for L in the second equation. This gives me (2W-6)*W=108. Distributing the W gives me 2W^2-6W=108, or W^2-3W-54=0. Using the quadratic formula, I get that W=9. Using the first equation, L=2*9-6=12. So the length is 12 and the width is 9.

Lin and her brother each created a scale drawling of their backyard, but a different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard Express the Lin's scale for the drawling without units. Type your answer in the format: 3:4 With no spaces
Answer:
1:12
Step-by-step explanation:
Give the following :
Lin's scale = 1 inch to 1 foot
Brother's scale = 1 inch to 1 yard
Lin's scale for the drawing without units :
To obtain this, convert foot to inch:
1 foot = 12 inches
Hence,
1 inch is equivalent to 12 inches
Hence, rewriting Lin's scale without units :
