Albert bought a jacket for $33.96, a pillow for $10.75, and a glove for $15.25. He paid $40 and the rest he borrowed from his friend. If albert got $0.04 in change from the cashier, how much did he borrow from his friend to pay all the items
Answers
he paid $40 so 59,96 - 40 = $19,96
the cashier gave him $0,04 so he actually gave $60 to the cashier which means that his friend gave him $19,96

Antonio has 150 baseball cards. He decided to give you 32% of his cards to you. How many cards did he give you?
Answers
Answer:
He gave you 48 cards.
Step-by-step explanation:
150 * 32% (which is also 0.32) is equal to 48.
Divide the percentage by 100.
32 / 100 = 0.32.
You then multiply 0.32 by 150 to get the part.
0.32 x 150 = 48.
32% of 150 is 48.
Your answer is 48 cards.

Can you help me with the problem listed in the pictures below? Please and thank you. Will mark BRAINLIEST!!! :)
Answers
Answer:
14 books
Step-by-step explanation:
Let b = number of books at the beginning
She sold 1/2 of the books
b - 1/2 b
This is how many she had left
Then she bought 7
b - 1/2 b + 7
this equals 14
b - 1/2 b + 7 = 14
Combine like terms
1/2 b + 7 = 14
Subtract 7 from each side
1/2 b = 14-7
1/2 b = 7
Multiply each side by 2
1/2 b * 2 = 7*2
b = 14
She started with 14 books
What two integers have the product of 28 and the sum of -11 ? a -2 and -14 b 4 and 7 c -4 and -7 d 2 and 14
Answers
Hey there! I'm happy to help!
Let's look at the factors of 28.
1,28
2,14
4,7
We see that 4 and 7 add to make 11, but not -11. Well, we can just make both of them negative and then it will be -11 and their product will still be 28. Our numbers are -4 and -7.

If one side of a square measures (3x − 8) ft. , find the area of the square. Show work.
Answers
Answer:
[tex]\huge\boxed{A=(9x^2-48x+64)ft^2}[/tex]
Step-by-step explanation:
The formula of an area of a square:
[tex]A=s^2[/tex]
[tex]s[/tex] - side of a square
We have [tex]s=(3x-8)ft[/tex]
Substitute:
[tex]A=(3x-8)^2[/tex]
METHOD 1:
Use [tex](a-b)^2=a^2-2ab+b^2[/tex]
[tex]A=(3x)^2-2(3x)(8)+8^2=9x^2-48x+64[/tex]
METHOD 2:
Use FOIL: [tex](a+b)(c+d)=ac+ad+bc+bd[/tex]
[tex]A=(3x-8)(3x-8)=(3x)(3x)+(3x)(-8)+(-8)(3x)+(-8)(-8)\\\\=9x^2-24x-24x+64=9x^2-48x+64[/tex]
Answer:
9x^2-48x+64 ft^2
Step-by-step explanation:
(3x − 8) (3x − 8)
Multiply 3x by (3x − 8)
3x(3x − 8)
9x^2-24x
Multiply - 8 by (3x − 8)
- 8(3x − 8)=-24x+64
Combine 9x^2-24x and -24x+64
9x^2-48x+64 ft^2

What is dilation?Dilation is a transformation, which is used to resize the object. Dilation is used to make the objects larger or smaller. This transformation produces an image that is the same as the original shape. But there is a difference in the size of the shape.
According to the information
The congruency can't be obtain after dilation.
Also, to make transformation rotation should be done.

The length of a rectangle is six times its width. If the perimeter of the rectangle is 140 yd, find its length and width.
Answers
Answer:
[tex] \boxed{ \sf{length \: of \: a \: rectangle = 60 \: yd}}[/tex]
[tex] \boxed{ \sf{width \: of \: a \: rectangle = 10 \: yd}}[/tex]
Step-by-step explanation:
Let the width of a rectangle be 'w'
Length of a rectangle ( l ) = 6w
Perimeter of a rectangle ( P ) = 140 yd
Finding the width of a rectangle
[tex] \boxed{ \sf{perimeter \: of \: rectangle= 2(length + breadth)}}[/tex]
[tex] \dashrightarrow{ \sf{140 = 2(6w + w)}}[/tex]
[tex] \dashrightarrow{ \sf{140 = 2 \times 7w}}[/tex]
[tex] \dashrightarrow{ \sf{140 = 14w}}[/tex]
[tex] \dashrightarrow{ \sf{14w = 140}}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{14w}{14} = \frac{140}{14}}} [/tex]
[tex] \dashrightarrow{ \sf{w = 10}}[/tex]
Width of a rectangle = 10 yd
Now, replacing / substituting the value of w in 6w in order to find the length of a rectangle
[tex] \dashrightarrow{ \sf{length = 6 \times x = 6 \times 10 = 60 \: yd}}[/tex]
Length of a rectangle = 60 yd

Solve by elimination.
5x - 6y = 27
7x + 6y = 9
Show work pls
Answers
Answer:
x = 3y = - 2Step-by-step explanation:
5x - 6y = 27 .......... Equation 1
7x + 6y = 9 ………… Equation 2
To solve using elimination add the second equation to the first one to eliminate y
That's
5x - 6y + 7x + 6y = 27 + 9
12x + 6y - 6y = 36
12x = 36
Divide both sides by 12
x = 3
Substitute it into any of the equations
Using equation 2
That's
7(3) + 6y = 9
21 + 6y = 9
6y = - 12
Divide both sides by 6
y = - 2
The solutions are
x = 3
y = - 2

What is the length of BC in the right triangle below?
A. ^234
B. 234
c. ^216
D. 216
Answers
We can use the pythagorean theorem to solve this
The pythagorean theorem = a^2 + b^2 = c^2, while
a = one leg
b = the second leg
c = the hypotenuse
In this problem,
a = 3
b = 15
c = ?
Let's plug our values into the pythagorean theorem
(3)^2 + (15)^2 = c^2
9 + 225 = c^2
Add together the left side
234 = c^2
Take the sqrt of both sides
sqrt(234) = c
The length of BC = sqrt(234)
