Answer: y=2
Step-by-step explanation:
Distribute the numbers -2 and 3...
6y-2y-2=3y-6+6
The -6 and 6 cancel each other out...
6y-2y-2=3y
Combine like terms....
4y-2=3y
Move 4y over....
-2=-y
Multiply both sides by -1.....
2=y
That’s your solution! Hope this helps!

Which Property of equality accurately completes Reason B?
A). Addition Property of Equality
B). Divison Property of Equality
C). Substitution Property of Equality
D). Subtraction Property of Equality
Answer:
D Subtraction Property of Equality
Step-by-step explanation:
Whenever we subtract the same number of expression from both sides of the equation, the equality remains the same.
Reason A. - Consecutive Interior Angles
Reason B. - Substitution Property of Equality
Reason C. - Subtraction Property of Equality
The Property of equality that accurately completes Reason B in the figure and flowchart proof is the Addition Property of Equality (A).
Explanation:The property of equality that accurately completes Reason B in the figure and flowchart proof is the Addition Property of Equality (A).
The Addition Property of Equality states that if you add the same number to both sides of an equation, the equality is still preserved. In other words, if A + B = B + A, you can add the same number to both sides to obtain A + B + C = B + A + C, where C is any number.
In the given figure and flowchart proof, the equation A + B = B + A represents the Addition Property of Equality, and by applying this property, we can conclude that Reason B should be completed with the Addition Property of Equality (A).

If f(x) = 7 + 4x and g(x) = 2x, what is the value of 8 (5)?
A)11/2
B)27/10
C)160
D)270
If the functions f(x) = 7 + 4x and g(x) =1/2x then the value of (f/g)(5) is 270, option D is correct.
What is a function?A relation is a function if it has only One y-value for each x-value.
The given functions are f(x) = 7 + 4x and g(x) =1/2x
We have to find the value of (f/g)(5)
We know that from properties of functions
(f/g)(a)=f(a)/g(a)
So let us find f(5) and g(5)
f(5)=27
g(5)=1/10
(f/g)(5)=27/(1/10)
=27×10
=270
Hence, if the functions f(x) = 7 + 4x and g(x) =1/2x then the value of (f/g)(5) is 270, option D is correct.

The sum of the interior triangles in a triangle is 180, so if we add all the angle measures together, we should get 180. Therefore, we can make an equation like this,
[tex]110-2x+x+50+5x-40=180[/tex]
Simplify this.
[tex]4x+120=180[/tex]
[tex]4x=60[/tex]
[tex]x=15[/tex]
Now we can find each angle measure.
[tex]110-2x[/tex]
[tex]110-2(15)[/tex]
[tex]110-30[/tex]
[tex]80[/tex]

Which is an equivalent form of the compound inequality −44 > −2x − 8 ≥ −8?
Answer:
22 and 0
Step-by-step explanation:
−44 > −2x − 8 ≥ −8?
/-2 - 44 > -2x / . -2 -8 ≥ -8
= 22 +8 =0
Answer:
An equivalent form of the compound inequality is the pair of single inequalities:
-2x - 8 < - 44, and −2x − 8 ≥ −8Explanation:
You can split the compound inequality into two equivalent inequalities by taking each side from the variable.
The compound inequality −44 > −2x − 8 ≥ −8 means that two conditions must be satisfied:
1. From the left side: - 44 > - 2x - 8
2. From the right side: −2x − 8 ≥ −8
Then, as a first approach you can tell that an equivalent form of the compound inequality is the pair of single inequalities:
-44 > -2x - 8, and −2x − 8 ≥ −8You should put the variable on the left sides, which will yield the best form of an equivalent pair of inequalitis.
- 2x - 8 < -44, and- 2x - 8 ≥ - 8That is the best choice of an equivalent form, and from there you can solve the inequalities which will permit to obtain the solution. Of course, you can manipulate the variable and find many other equivalent forms.
Notice, that both inequalities must be satisfied simultaneously.
This is how you solve that system
- 2x - 8 < -44nAdd 8 to both sides: - 2x < -36
Divide both sides by - 2 (you have to change the sign): x > 18
- 2x - 8 ≥ - 8-
Add 8 to both sides: - 2x ≥ 0
Divide by - 2 (again, you must change the sign): x ≤ 0
Then, the solution set is:
x > 18 and x ≤ 0 and that is an empty set, since x cannot be at the same time greater than 18 and less or equal to 0.This is, you conclude that the compound inequality is false, because there is not a value of x which is a solution.

Which is a reasonable first step that can be used to solve the equation
Answer:
Use distributive property:
2x + 12 = 3x - 12 + 5
Step-by-step explanation:
This can allow for combining like terms later on, and eventually isolating x as a variable.
For this case we have the following equation:
[tex]2 (x + 6) = 3 (x-4) +5[/tex]
The first step we must follow to solve the equation is to apply distributive property to the terms within the parenthesis:
[tex]a (b + c) = ab + ac[/tex]
Then, the equation is:
[tex]2x + 12 = 3x-12 + 5[/tex]
Answer:
The first step is to apply distributive property to the terms within parentheses.

If one share of XYZ stock cost $34.18 at the start of business on Monday morning, what is the price of the one share of XYZ stock at the close of business on Tuesday evening?
Answer:
1. $(x+0.03) - $x
2. $ 34.21
Step-by-step explanation:
Let the price of XYZ inc's share to be = $ x
On Monday, the price drops by $ 0.02 = $ x- $ 0.02 = $ (x-0.02)
New price of shares on Monday is = $ (x- 0.02)
On Tuesday the price goes up by $0.05 = $ (x-0.02) + $ 0.05 = $(x-0.02+0.05)
New price on Tuesday = $( x+ 0.03)..............................................(a)
Change in price of one share of XYZ's stock= Price on Tuesday - price of share

Basketball court has a perimeter of 278 feet the basketball court is 38 feet longer than it is wide find the length and the width of the garden justify your answer
ANSWER
[tex]w = 50.5[/tex]
[tex]l = 88.5[/tex]
EXPLANATION
The basketball court has a rectangular shape.
The perimeter of this court is calculated using the formula
[tex]P=2(l + w)[/tex]
It is given that,the court has a perimeter of 278ft. Let the width of the court be 'w' units, then the length is "w+38"
The perimeter then becomes:
[tex]2(w + 38+ w) = 278[/tex]
[tex]2w + 38= 139[/tex]
[tex]2w = 139 - 38[/tex]
[tex]2w = 101[/tex]
[tex]w = 50.5[/tex]
[tex]l = 50.5 + 38 = 88.5[/tex]
Check
[tex]P = 2(88.5 + 50.5)[/tex]
[tex]P = 2(139) = 278[/tex]
The surface area of a rectangular prism is increased by a factor of 16.
By what factor is the volume of the figure increased?
Answer:
The factor of the volume of the figure increased is 64
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its surface areas is equal to the scale factor squared and the ratio of its volumes is equal to the scale factor elevated to the cube
step 1
Find the scale factor
Let
z ----> the scale factor
z²=16
z=4 -----> scale factor
so
z³=4³=64
The factor of the volume of the figure increased is 64
Answer:
The volume of the rectangular prism will increase by a factor of 64.
Step-by-step explanation:
Surface area = [tex]length\times length[/tex]
or [tex]\sqrt{surface area} =length[/tex]
Therefore, the increase in the length of the sides will be = [tex]\sqrt{16}=4[/tex]
We know the volume is =[tex]length\times width\times height[/tex]
When there is increase in length of sides by 4 times, then volume will increase by [tex]4^{3}[/tex]
And [tex]4^{3}[/tex] = [tex]4\times4\times4=64[/tex]
Hence, the volume of the rectangular prism will increase by a factor of 64.
How is finding the fourth vertex of a parallelogram that is not a rectangle or a square the same as it is for a rectangle or square? How is it different?
well, the only difference from a parallelogram that is a square or a rectangle and one that isn't, is that the interior angles are 90° in the square and rectangle, however for other ones, like the one in the picture below, they are not 90°.
however, getting to any vertex, is just a matter of moving horizontally and vertically the same distances, as you see those arrows on the picture, since both pair of sides are parallel, one moves the same distance horizontall and vertically to get to the next vertex, so on that, is the same as for a square or rectangle as well.
is only different in that you're not moving alongside the segment, in a rectangle or a square, the lines are only vertical or horizontal, so you simply move straight to get the next vertex, on other parallelograms like the one below, you do move the same but is not alongside the segments.
