At a sale this week, a suit is being sold for $274.40. This is a 72% discount from the original price.
Answer:
Your new total with the sale is 76.83 dollars
Step-by-step explanation:
A printing company sells small packages of personalized stationery for $7 each, medium
packages for $12 each, and large packages for $15 each. Yesterday, the company sold 9
packages of stationery, collecting a total of $86. Three times as many medium packages
were sold as large packages.
Can someone set up the question? I’m unsure of what the equations would be.
Step-by-step explanation:
what's the question ? it does not say.
I assume it is "how many packages of what size were sold ?"
x = number of small packages
y = number of medium packages sold
z = number of large packages sold
x + y + z = 9
7x + 12y + 15z = 86
y = 3z
these are the 3 equations we get out of the question.
we put the third equation into the other two :
x + 3z + z = x + 4z = 9
7x + 12×3z + 15z = 7x + 36z + 15z = 7x + 51z = 86
it of this first equation we get
x = -4z + 9
and putting that into the other equation :
7×(-4z + 9) + 51z = 86
-28z + 63 + 51z = 86
23z = 23
z = 1
y = 3z = 3×1 = 3
x = -4z + 9 = -4×1 + 9 = -4 + 9 = 5
so, 5 small, 3 medium and 1 large packages were sold.

-2x+9y=-41
-2x-5y=1
Process of elimination
-2x+9y=41.... equation 1
-2x-5y=1 ....equation 2
________________
14y=43
y=43/14
y=43/14 in equation 1
-2x+9(43/14)=41
-2x+387/14=41
-2x=41-387/14
-2x=187/14
x=187/-28
x=187/28 , y=43/14
if you want to check your answer
-2(187/28)+9(43/14)=41

Step-by-step explanation:
Answer:x^2-x-3
Step-by-step explanation:
step 1-find area of rectangular lawn
(2x+1)(x+1)=2x^2+3x+1
step 2-find area of garden
(x+2)(x+2)=x^2+4x+4
step 3- subtract the two
=x^2-x-3

These are already solved but can someone explain how we got them, steps please! I really need it..
Answer:
1A,) 5x 2 and 3x are unlike terms and 9x 3 and 2x 2 are also unlike term
* so you have to put the like terms together to solve the equation
*then you say 9x 3 first because it is the biggest number (I think)
* then you put 5x 2 and 2x 2 together and 3x and x together too
* then you will get : 9x 3+ (5x 2 + 2x 2) + (3x -x)
:9x 3 + 7x 2 +2x
Note:in algebra 3x -x is like saying 3-1 aka x is seen as 1 but the one is invisible
haha
and unlike terms are terms that do not have the same variables or powers while like terms are terms that have the same variables or powers

- 2/7 divided by - 8/21
I like to use the way flip the second fraction then cross cancel then multiply.
(-2/7)/(-8/21)
= (-2/7)(-21/8) (cross cancel) so 8 / 2 = 4 and 21 / 7 = 3. The 7 and 2 becomes 1.
= (-1/1)(-3/4)
= 3/4 or decimal 0.75
Answer:
3/4
Step-by-step explanation:
(-2/7) / (-8/21)
= (-2/7) * (-21/8)
=(-2*-21) / (7*8)
=42/56
= 3/4 -simplified

Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
The similarity ratio is the ratio of corresponding sides, image to original
ratio = [tex]\frac{LK}{FG}[/tex] = [tex]\frac{24}{20}[/tex] = [tex]\frac{6}{5}[/tex] ( = 1.2 )
Simply the expression 49^1/2
Answer:
7
Step-by-step explanation:
[tex]49^{1/2}[/tex]=[tex]\sqrt{49}[/tex]. so just find the square root of 49. luckily, 49=7^2 so the answer is 7
