Lia brought 21 shirts and plants. Her total was $357. Pants cost $25 each, and shirts cost $14.50 each. How many of each item did she buy? Show your work
Will give points
Answer:
x=5 and y=16
Step-by-step explanation:
x = number of pants
y = number of shirts
Set up equations:
25x + 14.5y = 357x + y = 21Set the equations up as a system:
25x+14.5y=357
x+y=21
Steps:
Solve the system by substitution.
(You can also solve this system by elimination.)
25x + 14.5y= 357
x + y = 21
Step 1: Solve x+y=21 for x:
(x + y) − y = (21) − y(Subtract y from both sides)
x = −y + 21
Step 2: Substitute −y + 21 for x in 25x + 14.5y = 357:
25x + 14.5y = 357
25(−y + 21) + 14.5y = 357
−10.5y + 525 = 357 (Simplify both sides of the equation)
(−10.5y + 525) − 525 = (357) − 525(Subtract 525 to both sides)
−10.5y = −168
−10.5y / −10.5 = −168 / −10.5 (Divide both sides by -10.5)
y = 16
Step 3: Substitute 16 for y in x = −y + 21:
x = −y + 21
x = −16 + 21
x = 5 (Simplify both sides of the equation)
Answer:
x=5 and y=16

lara chooses a number less then 20 she divides it by 2 and then adds 6 she then divides whis result by 3 her answer is 4.5 what was the number she started with
Answer:
Lara started with the number 15.
Step-by-step explanation:
In order to solve this problem, you can write an equation representing the situation. You can do this by applying the described actions to a variable; I'll use n for this:
(n ÷ 2 + 6) ÷ 3 = 4.5
Now, you can just solve this equation for n:
(n ÷ 2 + 6) ÷ 3 = 4.5 (given)
n ÷ 2 + 6 = 13.5 (multiply both sides by 3)
n ÷ 2 = 7.5 (subtract 6 from both sides)
n = 15 (multiply both sides by 2)
So, now you know that Lara's starting number was 15.

The equation of an ellipse is x2/16 + y2/36= 1 , and the ellipse is centered at the origin. Find the vertices of the major axis and determine whether the ellipse has a horizontal or vertical major axis.
Answer:
steps below
Step-by-step explanation:
x²/16 + y²/36= 1
x²/4² + y²/6²= 1
Eclipse center ed origin: standard formula
²/radius of minor axis + y²/ radius of major axis =1
Vertices of major axis: (6 , 0) and (-6 , 0) ... horizontal
vertices of minor axis: (0 , 2) and (0 , -2) ... vertical

The circle has center O. Its radius is 6 cm, and the central angle measures 40. What is the area of the shaded region? Give the exact answer in terms of π, and be sure to include the correct unit in your answer.
Answer:
= 4π
Step-by-step explanation:
Area of the shaded region
Sector area = (central angle)/360° x area of circle
= (central angle)/360° x πr²
= 40°/360° x π6²
= 1/9 x 36π
= 36π/9
= 4π

Answer:
(4, 8) where =(x, y)
Step-by-step explanation:
x + 4(-x + 12) = 36
x -4x + 48 = 36
-3x = -12
x = 4
4 + 4y = 36
4y = 32
y = 8
There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy. Alia keeps all the cards down on a table with the pictures hidden and mixes them up. She then turns over one card and finds the picture of a rose on it. She removes this card from the table and turns over another card without looking. What is the probability that the card that Alia turns over has a rose on it? (1 point)
Group of answer choices
4 over 5
5 over 7
4 over 7
5 over 8
Answer:
P = 4/7
Step-by-step explanation:
There are 5 cards with a picture of a rose and 3 cards with a picture of a daisy.
Then we have a total of 8 cards.
Now Alia turns over one card, and this card has a picture of a rose, then she removes it.
This means that now there are 4 cards with a picture of a rose and 3 cards with a picture of a daisy, so now we have a total of 7 cards.
We want to find the probability that the next turned card has also a rose on it.
This will be equal to the quotient between the number of cards with a rose on it (4 cards) and the total number of cards (7)
Then the probability is:
P = 4/7
