Which expressions are equivalent to 3x+3(x+y)3x+3(x+y)3, x, plus, 3, left parenthesis, x, plus, y, right parenthesis
The question is incomplete. The complete question is :
Which expressions are equivalent to 3x+3(x+y)3x+3(x+y)3, x, plus, 3, left parenthesis, x, plus, y, right parenthesis ? Choose all answers that apply:
(Choice A) A 6x+3y6x+3y6, x, plus, 3, y
(Choice B) B 3(x+x+y)3(x+x+y)3, left parenthesis, x, plus, x, plus, y, right parenthesis
(Choice C) C 3xy3xy
Solution :
The equation is given as follows :
3x + 3(x+y)
We can simplify the equation in order to determine the equivalent expression.
Now applying the distributive property,
[tex]$3x+(3)(x)+(y)(3)$[/tex]
[tex]$=3x+3x+3y$[/tex]
When we add the like terms we get :
3x+3x+3y = 6x + 3y
When we factor out the term 3, we get :
3x + 3x + 3y = 3(x + x + y)
So, the expressions in options (B) and (C) are equivalent to the expression 3x + 3(x + y).

Find the area of the triangle
Answer:
C) 17.1 square units
Step-by-step explanation:
Use Heron's formula to calculate the area of the triangle:
[tex]Area = \sqrt{s(s-a)(s-b)(s-c)}[/tex] where [tex]s=\frac{a+b+c}{2}[/tex] which represents the semi-perimeter of the triangle:
[tex]s=\frac{9.9+6.1+6}{2}=11[/tex]
Therefore:
[tex]Area = \sqrt{11(11-9.9)(11-6.1)(11-6)}\\[/tex]
[tex]Area = \sqrt{11(1.1)(4.9)(5)}\\[/tex]
[tex]Area = \sqrt{296.45}\\[/tex]
[tex]Area = 17.2[/tex]
Therefore, the closest answer choice is C) 17.1 square units

A 25-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is one inch more than five times the length of the first piece. Find the lengths of the pieces.
Answer:
3 inch 6 inch 16 inch 3+6+16 = 25
Step-by-step explanation:
First piesce = F
Second piece = 2F
third piece = 5F+1
F + (2F) + (5F+1) = 25
8F +1 = 25
subtract 1 om both sides
8F = 24
divide both sides by 8
F= 3
3X2= 6
3X5 +1 = 16

The straight line PQ with P(1,6) and Q(-6, 1). PQ is mapped onto P'Q' by a reflection in the line = 2. What are the coordinates of P
Answer:
[tex]P' = (1,-2)[/tex]
Step-by-step explanation:
Given
[tex]P = (1.6)[/tex]
[tex]Q = (-6,1)[/tex]
Reflection over: [tex]y = 2[/tex]
Required
Determine the coordinates of P'
From the given coordinates, the y coordinates of P is 6 and the line of reflection is at y = 2
Since we are to reflect over y = 2, only the y coordinate of P will be affected.
The idea behind reflecting a point over a line is to have an equal distance between [the original point & the line of reflection] and [the new point & the line of reflection]
So, what to do is:
First, calculate the difference between the y coordinates of P and the line of reflection.
The y coordinate of P is 6 and the line of reflection is at y = 2.
So, the difference is: 6 -2 = 4
Next, subtract the calculated difference from the line of reflection to get the y coordinate of P'
y coordinate of P' = 2 - 4 = -2
Hence, the coordinate of P' is: (1,-2)
Hadi randomly pulls a sock from a drawer with 3 patterned socks, 6 gym socks, 7 striped socks, and 4 red socks. What is
the probabilty that Hadi does not choose a red sock?
Answer:
Stepp-by-step explanation:
Answer: 80% or 4/5
Step-by-step explanation:
You have a total of 20 socks, and there are 4 red ones, so there's a 16/20 = 8/10 = 4/5 or 80% chance that you will not pull out a red sock.
Hope this helps!

Parallelogram Properties - Angles
Answer: x=30°
Step-by-step explanation:
A parallelogram always add up to 360°.
Opposite angles like F and H are always the same, so H=150°.
150+150=300 (what angles F and H add up to)
So we can do:
360-300=60
Now we know that the angle x and E have to add up to 60 but still be the same, so x will equal 30°.
We can check this by adding up all of the sides:
150+150+30+30=360°
Hope this helped :)
The number 18 is decreased to 16. What is the percentage by which the number was
decreased, to the nearest tenth of a percent?
Answer:
11.1 %
Step-by-step explanation:
2/18 = 11.1%
The percentage of the number decreased is 11.1%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Initial number = 18
Final number = 16
The change in the value of the number.
= 18 - 16
= 2
The percentage decreased.
= (Change in the number / Initial number) x 100
= 2/18 x 100
= 200/18
= 11.11%
= 11.1 %
Thus,
The percentage decreased is 11.1%.

Step-by-step explanation:
Finding the height:Greatest common factor (GCF) is the highest number that is a factor of 2 numbers. Not sure if that makes sense.
For example, GCF of 8 and 4 is 4, because 4 is the highest factor that fits into both numbers. 4x2=8 and 4x1=4.
In this case, the height is 7, because that's the GCF of 21 and 70. There's no bigger common factor than that. 7x3=21 and 7x10=70
Finding the length and area:Now that we know the "height", even though there's no such thing as height when calculating the area, we know the length.
The area of something is length x width. Your assignment calls it height for some reason so we'll use height x length.
Area of the 2 shapes is already given, which is 21n for the first shape. Length of the first shape is 3n because 3nx7=21n. Recall that 7 is what we found earlier.
As we can see, the "height" of the 2nd shape is the same as the first, therefore it should also be 7.
Since we are given the area of the 2nd shape, we now know its length. Length of 2nd shape is 10, because 7x10=70.
Suppose Lindsay’s mom invests $10,000, part at 3%, and the rest at 2.5%, in interest-bearing accounts.-10,00007.5 The totally yearly investment income (interest) is $283. How much did Lindsay’s mom invest at each rate?
Answer:
she invested 6600 at 3% and 3400 at 2.5%
Step-by-step explanation:
Simple interest = amount deposited x time x interest rate
Let the amount deposited in in the account bearing 3% interest by represented with a
Let the amount deposited in in the account bearing 2.5% interest by represented with (10,000 - a)
a x 0.03 + (10,000 - a) x 0.025 = 283
0.03a + 250 - 0,025a = 283
collect like terms
0.03a - 0.025a = 283 - 250
0.005a = 33
a = 6600
the amount deposited in the 2.5% account = 1000 - 6600 = 3400

1) Mark and Huong are selling flower bulbs for a school fundraiser. Customers can buy packages
tulip bulbs and packages of crocus bulbs. Mark sold 9 packages of tulip bulbs and 1 package of
crocus bulbs for a total of $127. Huong sold 6 packages of tulip bulbs and 6 packages of crocus
bulbs for a total of $186. Find the cost each of one package of tulips bulbs and one package of
crocus bulbs.
Answer:
Package of tulip bulbs = $12
Package of crocus = $19
Step-by-step explanation:
Let b = cost of a package of bulbs
c = cost of a crocus package
Mark: (1) 9b + c = 127 Huong: (2) 6b + 6c = 186
c = 127 - 9b 6b + 6(127 - 9b) = 186
6b + 762 - 54b = 186
- 48b = -576
b = 12
c = 127 -9(12)
c = 127 - 108 = 19
