Which property is illustrated by the equation
3x – 6y = 3(x - 2y)?
1. associative
2.Commutative
3.distributive
4.closure
Answer: 3. Distributive
Step-by-step explanation:
3(x -2y) = 3x - 6y To get from left to rigth, you have to multiply them which is the same as distribitue.
3(x) - 3(2y) = 3x - 6y
lisa purchased almonds for 3.50 per round. she spent a total of 24.50, how many pounds of almonds did she purchase?
Answer:
7 pounds
Step-by-step explanation:
In order to find the answer to this question add the cost of a pound worth of almonds to the total amount of money she spent altogether in till you cannot add anymore.
[tex]3.50+3.50=7.00[/tex]
[tex]7.00+3.50=10.50[/tex]
[tex]10.50+3.50=14.00[/tex]
[tex]14.00+3.50=17.50[/tex]
[tex]17.50+3.50=21.00[/tex]
[tex]21.00+3.50=24.50[/tex]
=[tex]7lb[/tex]
Check work:
[tex]3.50\times7=24.50[/tex]
Hope this helps
Answer:
Step-by-step explanation:
3.50 per pound
Let each pound represent x
Total of almonds bought is 24.50
therefore 3.50x = 24.50
x = 24.50 ÷3.50
x= 7
What is the slope of any line that is perpendicular to the line that contains the points (8, 8) and (12, 12)?
Answer:
slope(m)=-1
Step-by-step explanation:
let the point (8,8) and (12,12) be ([tex]x_{1}[/tex],[tex]y_{1}[/tex]) and ([tex]x_{2} , y_{2}[/tex])
slope of point([tex]m_{1}[/tex])=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
=(12-8)/(12-8)
=1
let the slope of perpendicular line to given point be [tex]m_{2}[/tex]
now ,
[tex]m_{1} m_{2}[/tex]=-1
so [tex]m_{2}[/tex]=-1
Find the area of quadrilateral ABCD and RST.
Answer:
ABCD is 6 units 2×3=6
im not really sure about RST but i think it would be 4 or 5 units because it just looks like there is about that many inside.
We can see here that the area of quadrilateral ABCD = 12 units².
While the area for triangle RST = 5 units².
What is quadrilateral ?A quadrilateral is a polygon with four sides, four vertices, and four angles. The word "quadrilateral" is derived from the Latin words "quadri" (meaning "four") and "latus" (meaning "side"). Quadrilaterals are classified based on the lengths of their sides, the measures of their angles, and other specific properties.
Area of the parallelogram ABCD = B × H = 3 units × 4 units = 12 units².
Area of the triangle RST = 1/2bh = 1/2 × 5 units × 2 units = 1/2 × 10 units = 10/2 units = 5 units².

slope of (-4,13) and (6,-2)
Answer:
-3/2
Step-by-step explanation:
You can do this using slope formula, y2-y1/x2-x1.
We first substitute in the numbers--> -2 - 13/ 6 - (-4)
Then we simplify to get--> -15/10 = -3/2
You could also graph the points and find the rise over run.

Help plz. I’ve been stuck for almost a hour
Answer: x=10 and y=25
Step-by-step explanation:
ok, so since we know straight angles=180 degrees, so since one part=100, the other smaller angle=80. This means that 11x-30=80 and 5y-25=100. 11*10=110, and 110-30=80, so x=10. 5*25=125, and 125-25=100, so y=25. And lol. me too. When I used to do these problems, I was stuck for a very, very long time. Just try to use logic most of the time.
Answer:
y = 25 and x = 10
Step-by-step explanation:
the angles on top and on bottom are equal so...
5y - 25 = 100
5y - 25 + 25 = 100 + 25
5y = 125
5y/5 = 125/5
y = 25
Every line is 180 degrees so we know that if the top and bottom angles are 100 then the other angles need to equal 80
11x - 30 = 80
11x - 30 + 30 = 80 + 30
11x = 110
11x/11 = 110/11
x = 10

Answer:
∠ACB = 72
Step-by-step explanation:
OAD is straight line.
∠DAB + ∠OAB = 180
142 + ∠OAB = 180
∠OAB = 180 - 142
∠OAB = 38
ΔAOB is isosceles triangle. OA = OB = radius
∠OAB = ∠OBA = 38 {angles opposite to equal sides or equal}
In ΔAOB ,
∠OAB + ∠OBA + ∠AOB = 180 {Anlge sum property of triangle}
38 + 38 + ∠AOB = 180
76 + ∠AOB = 180
∠AOB = 180 - 76
∠AOB = 104
THe angle subtended by an arc of a circle at the center is double the angle subtended by it at any point on the remaining part of the circle
∠AOB = 2*∠ACB
∠ACB = ∠AOB/2
= 104/2
∠ACB = 72

the sum of two numbers is 18 their difference is 8
Answer:
13 and 5
Step-by-step explanation:
x+y=18
x-y=8
_____
2x=26
x=13
So the first number must be 13
13+y=18
y=5
And the second number must be 5
When we write out the system of equations, we will get:
x+y=18
x-y=8
We can then use elimination to get just one variable.
x+y=18
+x-y= 8
Which gives us: 2x=26
We then divide by 2 and get: x=13
We next plug that into one of the two equations and solve for the other variable: (13)+y=18
We subtract 13 from both sides and get: y=5
So the two numbers are 13 and 5.

Hans is sitting in a movie theater, 19 meters from the screen. The angle of elevation from his line of sight to the top of the screen is 15°, and the angle of depression from his line of sight to the bottom of the screen is 22°. Find the height of the entire screen. Do not round any intermediate computations. Round your answer to the nearest tenth.
Answer:
12.8 m
Step-by-step explanation:
From the diagram :
Height PR = 19m
Using Pythagoras :
From triangle PQR:
QR = x
Tan θ = opposite / Adjacent
Tan 22° = x / 19
x = tan 22° * 19
x = 0.4040262 * 19
x = 7.6764982 m
From triangle PRS:
SR = y
Tan θ = opposite / Adjacent
Tan 15° = y / 19
y = tan 15° * 19
y = 0.2679491 * 19
y = 5.0910346
Height of entire screen :
(7.6764982 + 5.0910346) m
= 12.7675328 m
= 12.8 m
