Jayden and Carson are selling T-Shirts and sweatshirts with the school logo. Jayden sells 9 T-Shirts and 3 sweatshirts for 288$. Carson sells 1 T-Shirt and 6 sweatshirts for 270$. Find the selling prices of each item
Answer: cost of T-shirts = $18
cost of sweatshirt = $42
Step-by-step explanation:
Let the cost of T-shirts be x
Let the cost of sweatshirt be y
The information given in the question can be used to form an equation that'll be:
9x + 3y = 288 ...... i
1x + 6y = 270 ........ ii
Multiply equation i by 1
Multiply equation ii by 9
9x + 3y = 288 ....... iii
9x + 54y = 2430 ..... iv
Subtract iii from iv
51y = 2142
y = 2142 / 51
y = 42
The cost of a sweatshirt is $42
Since Carson sells 1 T-Shirt and 6 sweatshirts for 270$. The cost of a t-shirt will be:
= 270 - 6(42)
= 270 - 252
= $18

now we khow that
slope (m) =y2-y1/x2-x1
= 15-6/5-9

1) a^-8/5
2) (9b^4)^2/3
3) (8x^5)5/7
PLEASE I NEED HELP!!!!!!
Answer:
1/a^8/5 for the first, 9b^8/3 for the second, and 8x^25/7 for the third
Step-by-step explanation:
1) With neg exponents, you can just take it and flip it, and make the exp pos i.e. 1/a^8/5
2) When there is an exponent outside of parenthesis of a number with an exponent, you multiply the exponents together i.e. 9b^8/3
3) The same applies to this as the 2nd, we just multiply to get 8x^25/7

A- $312
B- $449
C- $3291
D- $4189
Answer:D
Step-by-step explanation:
The total earn in commission by Tamika for January is $449.
What is percentage?A portion per hundred is what the percentage denotes. Percentage refers to one in a hundred. The sign "%" is used to denote it. Indicative percentages include: A fraction of ten percent is one tenth.
To find the percentage of a number between two numbers, number with the other and then multiply the result by 100.
Calculate the commission earned:
Tamika is paid a 12% commission on her sales.
In January her sales total was $3740.
12% of 3740 is,
=> (12×3740)/100 = 448.8
= 449
Therefore, the commission earned by Tamika for January is $449.

Define the variables for the situation. Then enter an equation.
The pencils were divided into 8 groups of 2.
p = (select)
Enter an equation:
=
8
Answer:
p = 16/8 = 2
Step-by-step explanation:
We know that the pencils were divided into 8 groups of 2.
Then the total number of pencils is equal to 8 (the number of groups) times 2 (the number of pencils in each group)
8*2 = 16
The total number of pencils is 16.
Then the operation of dividing 16 pencils into 8 groups is written as:
16/8
And we know that this is equal to 2, then the operation is:
16/8 = 2.
Then the equation is:
p = 16/8 = 2
where p represents the number of pencils in each group.

Answer:

6 y = 6-5 1 (6, 1)
0 y = 0-5 -5 (0, -5)
5 y = 5-5 0 (5, 0)
-2 y = -2-5 -7 (-2, -7)
The graph of the line y = x-5 is attached below.
Step-by-step explanation:
Given the function
y = x-5
substitute x = 6 in the function
y = 6-5 = 1
so
y = 1
(x, y) = (6, 1)
substitute x = 0 in the function
y = x-5
y = 0-5 = -5
so
y = -5
(x, y) = (0, -5)
substitute x = 5 in the function
y = x-5
y = 5-5 = 0
so
y = 0
(x, y) = (5, 0)
substitute x = -2 in the function
y = x-5
y = -2-5 = -7
so
y = -7
(x, y) = (-2, -7)
Hence, the table becomes
x y = x-5 y (x, y)
6 y = 6-5 1 (6, 1)
0 y = 0-5 -5 (0, -5)
5 y = 5-5 0 (5, 0)
-2 y = -2-5 -7 (-2, -7)
The graph of the line y = x-5 is attached below.

The length of a rectangle is 2m longer than its width.
If the perimeter of the rectangle is 24m , find its area.
Answer:
35m
Step-by-step explanation:
length = 2+w
width = w
Perimeter = 2(length)+2(width)
24 = 2(2+w)+2(w) = 4+2w+2w = 4+4w
24=4+4w
4w=20
w=5
width =5
length = 2+5 = 7
Area = (length)(width) = 5(7) = 35m
solve for x with 9x+1 and 88? i don’t know how to and i really need it. attachment has the picture.
Answer:
x = 5
Step-by-step explanation:
We know that adding up all the degrees in a triangle will give you 180. So, subtracting the given angle from 180 will give us the sum of the missing angles: 180 - 88 = 92.
Since the diagram shows us that the triangle is isoscles, we know that the missing two angles are the same and equivalent. So, in order to get the value of one angle, we divide the sum of angles by 2: 92/2 = 46.
Now that we've found the value of one angle, we set it equal to the equation given to find the value of x: 9x + 1 = 46.
Last but not least, solve for x: 9x = 45 --> x = 5

An electrician charges $40 for each hour plus a $25 surcharge. The electrician raises the charges for each hour by $5. Write an equation that represents the new cost c of a job that take h hours
Answer:
c = 45h + 25
Step-by-step explanation:
The only difference between what the electrician used to charge and what he/she charges now is an increase of $5. Therefore, instead of charging $40 he is now charging $45. Using this new information we can create the following equation to calculate the total cost of a job. We do this by multiplying the cost per hour ($45) by the total number of hours (h) and then adding the surcharge.
c = 45h + 25
Write an equation in point-slope form of the line that passes though the given points. Then, write the equation in slope intercept form.
(-1,-2) and (2,4)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
(-1, -2)(2, 4)Finding the slope between (-1, -2) and (2, 4)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-1,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:4\right)[/tex]
[tex]m=\frac{4-\left(-2\right)}{2-\left(-1\right)}[/tex]
[tex]m=2[/tex]
Using the point-slope form
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where m is the slope of the line and (x₁, y₁) is the point
substituting the values m = 2 and the point (-1, -2)
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y -(-2) = 2(x-(-1)[/tex]
Thus, the point-slope form of the line equation is
[tex]y -(-2) = 2(x-(-1)[/tex]
now, write the slope-intercept form of the line equation y = mx+b
[tex]y-\left(-2\right)=2\left(x-\left(-1\right)\right)[/tex]
[tex]y+2=2\left(x+1\right)[/tex]
subtract 2 from both sides
[tex]y+2-2=2\left(x+1\right)-2[/tex]
Simplify
[tex]y=2x+0[/tex]
[tex]y = 2x[/tex]
Therefore, the equation in slope-intercept form is:
[tex]y = 2x[/tex]can anyone help me on the bottom question?
