If the first step in the solution of the equation 2x - 8 = 5x + 3 is "subtract 2x," then in the form of a paragraph, explain in
complete sentences the next steps necessary to completely solve the equation for x. Include the final answer in your
explanation. Complete your work in the space provided or upload a file that can display math symbols if your work
requires it
Answer:
step by step below.
Step-by-step explanation:
after subtracting the 2x, youd have 3x on the right side. and they you would want to get the numbers on one side, so subract the 3 to the left side. and then you would have -11.
[tex]2x -8= 5x +3 \\-2x = -2x \\-8=3x+3 \\-3= -3 \\-11=3x \\[/tex]
solve for x if necessary
Kelli buys a new backpack for $35. There is a 20% discount and a 7% tax. What will be the final cost of the backpack?
Answer:
29.96
Step-by-step explanation:
First find the discount
35 * 20 %
35*.2
7
Subtract the discount from the price
35-7
28
Now find the tax on the new price
28* 7%
28 *.07
1.96
Add the tax to the new price
28+1.96
29.96
(5x-23)
(7x-1)*
Help me please
Answer:
(5x-23)° + (7x-1)° = 180°
5x-23 + 7x-1 = 180
12x - 24 = 180
12x = 204
x = 17
.°. (5x-23)° = 62°
& (7x-1)° = 118°

Eugene has to buy cupcakes for a picnic. He needs to make sure that there are more than 8 cupcakes so each of his friends gets at least one cupcake. If Eugene buys y boxes that each contain 4 cupcakes, which inequality represents this situation?
A.
y < 8
B.
y > 8
C.
4y > 8
D.
4y < 8
Answer:
C
Step-by-step explanation:
4xy=4y
since each friend must get at least a cupcake, 4y must be larger than 8

(Help fast plz!)Which statement is true regarding the graphed functions
Given:
The graphs of two functions f(x) and g(x).
To find:
The correct statement about the functions.
Solution:
In the given graph blue line represents the graph of f(x) and the red line represents the graph of g(x).
From the given graphs it is clear that the graphs of the functions interest each other at point (-2,4). It means,
[tex]f(-2)=4[/tex]
[tex]g(-2)=4[/tex]
So, we conclude that
[tex]f(-2)=g(-2)[/tex]
Thus the option D is correct.
We can check other options.
[tex]f(4)=-14[/tex]
[tex]g(4)=10[/tex]
[tex]f(4)\neq g(4)[/tex]
So, option A is incorrect.
[tex]g(-2)=4[/tex]
[tex]f(4)\neq g(-2)[/tex]
So, option B is incorrect.
[tex]f(2)=-8[/tex]
[tex]f(2)\neq g(-2)[/tex]
So, option C is incorrect.
Therefore, the correct option is D.

Jackie is making flower arrangements. She has 2 roses and 4 daisies. If Jackie wants to make all the arrangements identical and have no flowers left over, what is the greatest number of flower arrangements she can make?
help<3
Let's explore possible case scenarios.
---------------------
Case A) Each person gets a rose and a daisy (2 flowers per person)
In this case, Jackie can make 2 such arrangements because she has 2 roses. We have 2 left over daisies.
---------------------
Case B) Each person gets a rose only (1 flower per person)
Only two arrangements are possible for the same reason as case A. In this situation, we have 4 left over daisies.
----------------------
Case C) Each person gets a daisy only (1 flower per person)
We have 4 arrangements possible because we have 4 daisies. The left over flowers are the 2 roses.
-----------------------
Case D) Each person gets 2 roses
Only one such arrangement is possible, so this only applies to one person really. You can say that 2/2 = 1. We have 4 left over daisies in this case.
-----------------------
Case E) Each person gets 2 daisies
Since 4/2 = 2, this means we can make 2 arrangements. There are 2 left over roses.
------------------------
Case F) Each person gets 2 daisies and 1 rose
We can see that 4/2 = 2 and 2/2 = 1, meaning that we can make at most 2 arrangements here. There are no leftovers. In contrast, the other cases do have leftovers of some kind.
------------------------
In short, you can do trial and error to see which case works to fit the conditions your teacher set. Case F is what we go for to have each flower bouquet consist of 2 daisies and 1 rose. We'll get 2 bouquets possible. Notice how cases A through E have at least one left over flower (either of one kind or both types), while case F has no leftovers.
please show me how you do this question
Answer:
Use the formula SA=2×length×width+2 length× height+2×height×width. With this I believe your answer should be 13.5. Sorry if it's wrong since the answer choices don't line up but thats the only way it makes sense for me.
If -10x – 9y = -7 is a true equation, what would be the value of
-30x – 27y?
Answer:
-30x-27y = -21
Step-by-step explanation:
We know that;
-30x-27y = 3(-10x-9y)
Recall, -10x-9y = -7
Thus; -30x-27y = 3(-7) = -21

Which of the equations below represents a line perpendicular to the x-axis?
A. X=3
B. X=3y
C. X=y
D. X=-3y
Answer: A. x = 3
This is a vertical line that goes through 3 on the x axis. Two points on this line are (3,0) and (3,1). Any vertical line is perpendicular to the x axis.
Can someone help me? It's urgent and thank you!
Answer:
d = 6
Step-by-step explanation:
Since the line is horizontal then the distance from B to C is the distance between the x- coordinates.
d = | - 3 - 3 | = | - 6 | = | 6 | = 6
Answer:
option C
Step-by-step explanation:
[tex]distance, d = \sqrt{(x_B- x_C)^2 + (y_B - y_C)^2}[/tex]
[tex]=\sqrt{(-3 -3)^2 + (6 - 6)^2 }\\\\=\sqrt{(-6)^2 + 0 }\\\\=\sqrt{36}\\\\= 6[/tex]
If a+b=13, and ab-40, then find a3+b3
Answer:
[tex]637[/tex]
Step-by-step explanation:
Step 1: Set Up System of Equations
[tex]a + b = 13[/tex]
[tex]ab = 40[/tex]
Solve for a in the first equation
[tex]a = 13 - b[/tex]
Subsitur that in for the 2nd equation
[tex](1 3 - b)(b) = 40[/tex]
[tex] - b {}^{2} + 13b = 40[/tex]
[tex] - {b}^{2} + 13b - 40[/tex]
[tex] - (b - 5)(b - 8)[/tex]
Set each monomial to zero
Think of a number that adds to 13 and multiply to 40.
Th
[tex]b = 5[/tex]
[tex]b = 8[/tex]
So the answer is 5 and 8. Remember factos are interchangeable so a and b can be either 8 or 5.
Cubed both 5 and 8.

A rectangular prism with a volume of 222 cubic units is filled with cubes with side lengths of \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction unit.
How many \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction unit cubes does it take to fill the prism?
Answer: 128 cubes
Step-by-step explanation:The dimension of the rectangular prism is not given, assumed not important.
Find the volume of 1 cube:
Volume = 1/4 x 1/4 x 1/4
Volume = 1/64 units³
Find the number of cubes that can go into the prism:
Number of cubes = 2 ÷ 1/64
Number of cubes = 128
What of the angle is the vertex?
Answer:
Vertex: The common end point at which the two rays meet to form an angle is called the vertex. Here, the point O is the vertex of ∠AOB. We can find angles in various things around us, such as in a pair of scissors, a hockey stick, a chair.
