Answer:
x= -1/5
Step-by-step explanation:
1
Add 9x9x to both sides.
x+9x=-2x+9x=−2
2
Simplify x+9xx+9x to 10x10x.
10x=-210x=−2
3
Divide both sides by 1010.
x=-\frac{2}{10}x=−102
4
Simplify \frac{2}{10}102 to \frac{1}{5}51.
x=-\frac{1}{5}x=−51
The graph represents the relationship between the cost of renting a trailer y for x hours,, please help
Answer:
The relationship is not proportion because the value of [tex]\frac{y}{x}[/tex] is not equivalent for each point in the relationship ⇒ C
Step-by-step explanation:
The relationship between x and y are proportional if [tex]\frac{y}{x}[/tex] = k, where k is a constantThe proportional relation represented graphically by a line passes through the origin pointLet us use the information, above to solve the question
→ From the given graph
∵ The coordinates of the points are (1, 10), (2, 20), (4, 25), (6, 40)
∵ The equation of proportion is [tex]\frac{y}{x}[/tex] = k
→ Let us check if all the points satisfy the equation or not
∵ x = 1 and y = 10
∴ [tex]\frac{10}{1}[/tex] = k
∴ 10 = k
→ Check the other points if they give the same value of k or not
∵ x = 2 and y = 20
∴ [tex]\frac{20}{2}[/tex] = k
∴ 10 = k
∵ x = 4 and y = 25
∴ [tex]\frac{25}{4}[/tex] = k
∴ [tex]\frac{25}{4}[/tex] = k
∵ x = 6 and y = 40
∴ [tex]\frac{40}{6}[/tex] = k
∴ [tex]\frac{20}{3}[/tex] = k
∵ Not all points satisfy the same value of k
∴ The relation does not represent a proportional relation
The relationship is not proportion because the value of [tex]\frac{y}{x}[/tex] is not equivalent for each point in the relationship.

Rewrite in simplest terms: -3(-4g-6g-2)-8g
Answer:
22g+6
Step-by-step explanation:
-3(-4g-6g-2)-8g To simplify this, we have to distribute first.
12g+18g+6-8g Now, we can combine like terms. (I underlined the parts with the variable to make it easier to see which parts were considered like terms.)
22g+6 This is your simplified answer!!

Which equation correctly applies the distributive property?
−1.5⋅(6⋅1.25)=(−1.5⋅6)⋅1.25
70+2.028=(70⋅2)+(70⋅0.02)+(70⋅0.008)
(0.7⋅0.7)+(0.7⋅0.9)+(0.7⋅0.2)=0.7⋅(0.7+0.9+0.2)
−2.5⋅0.6⋅5.8=−2.5⋅5.8⋅0.6
i dont know ethrreer
Step-by-step explanation:
Answer:
Step-by-step explanation:The distributive property dictates that:
a(b + c) = ab + ac
Thus,
(0.7 x 0.7) + (0.7 x 0.9) + (0.7 x 0.2)
= 0.7(0.7 + 0.9 + 0.2)
follows the distributive property. The third option is correct.

Rhianna was doing research for a report about the highest mountains in the United States. She read that the Grand Teton in Wyoming is about 1.37 × 104 feet high. How should Rhianna write the height of the Grand Teton in standard form on her report?
Answer:
1.37 × 10⁴ feet
Step-by-step explanation:
Standard form is a way or method used in mathematics to write very large or very small numbers in a compact form by raising them to the power of 10 (exponents)
She read that the Grand Teton in Wyoming is about 1.37 × 10⁴ feet high.
The standard form of writing this height = 1.37 × 10⁴ feet.

Solve for x.
a) 30
b) 27
c) 33
Answer:
x = 27
Step-by-step explanation:
The angle at any point on a straight line is 180 degrees.
The middle line over there is creating a right angle which is 90 degrees.
This must mean that both sides are 90 degrees.
3x+9 = 90

Please help, which expression is equivalent to....
Answer:
a
Step-by-step explanation:
1/3 (1/2x -9) = 1/2 ( x + 18)
1/6x -3 = 1/2 +9
1/4x -3 =9
1/4x =12
x=48
What mistake was made in the problem ?
Answer:
1/6x - 1/2x does not equal 1/4. They made a mistake in the second to third line.
Step-by-step explanation:
It should have been -1/3x - 3 = 9, which gives you x = -36.
1/6 - 1/2 = 1/6 - 3/6 = -2/6 = -1/3
The mistake is in the third step, the subtraction was done without taking LCM. The value of x is -36.
What is simplification?The numerical expression having two or more operations can be simplified by using ‘BODMAS’ rule, where the letters B, O, D, M, A, S stand for Brackets , orders (powers/indices or roots) , Division, Multiplication, Addition and Subtraction respectively.
For the given situation,
The expression is 1/3 (1/2x -9) = 1/2 ( x + 18).
We need to simplify the expression to find the mistake done by them.
⇒ [tex]\frac{1}{3}(\frac{1}{2}x-9 ) = \frac{1}{2}(x+18)[/tex]
⇒ [tex]\frac{1}{6}x-3 = \frac{1}{2}x+9[/tex]
⇒ [tex]\frac{1}{6}x-\frac{1}{2}x = 9+3[/tex]
⇒ [tex]\frac{-2x}{6}=12[/tex]
⇒[tex]\frac{-1}{3}x=12[/tex]
⇒ [tex]x=-36[/tex]
Hence we can conclude that the mistake is in the third step, the subtraction was done without taking LCM. The value of x is -36.

Step-by-step explanation:
Suppose the function E(c) represents the earnings of a volleyball team from selling cupcakes. Describe an appropriate domain of this function. Include a description of the kinds of numbers in the domain as well as any limitations on their values.
Answer:
When we have a function y = f(x) we define the domain as the set of the values of x, and the range as the set of the values of y.
In this case we have the function:
E(c) where c represents the number of cupcakes sold by the team.
In this case, the domain will be the possible values that c can take.
The restrictions are:
c ≥ 0.
They can not sell a negative number of cupcakes.
c must be an integer because they can not sell a 0.342 of a cupcake, so the domain is discrete.
c may have an upper limit (for example, if they made 500 cupcakes, they can not sell more than 500) But we do not know any upper limit, so we can ignore this restriction.
Then we can define the domain as:
D = {0, 1, 2, 3, ...}

2/5 divided by 8/5 This is dividing fractions
Answer:
The correct answer is 0.25 and if you're looking for fraction form its 1/4.
Step-by-step explanation:
Final Answer:
1/4
Step-by-step explanation:
[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{8}{5}[/tex]
[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{5}{8}[/tex] (reciprocal method)
[tex]\frac{2}{5}[/tex] × [tex]\frac{5}{8}[/tex] = [tex]\frac{10}{40}[/tex] (changing the operation to multiplication, then multiply the fractions)
[tex]\frac{10}{40}[/tex] ⇒ [tex]\frac{1}{4}[/tex] (reduce the answer)
Final Ans: 1/4

You practice playing your guitar every day. You spend 15 minutes practicing chords and the rest of the time practicing a new song. So the total number of minutes y you practice for the week is given by y=7(15+x), where x is the number of minutes you spend on practicing a new song. Solve the equation for x.
Answer:
x=(y-105)/7Step-by-step explanation:
Given that the total time taken to practice is given by the expression as
y=7(15+x)
Simplifying the expression we have
y=105+7x
Solving for x (that is making x subject of formula we have)
7x=y-105
Divide both sides by 7 we have
x=(y-105)/7
Therefore the expression is
x=(y-105)/7

8.) Henry's MP3 player has 512MB of memory.
He has already downloaded 287MB and will
continue to download m more megabytes.
Write and solve an inequality that shows how
many more megabytes he can download.
Answer:
Henry can download at most 225 MB more.
Step-by-step explanation:
The capacity of Henry's MP3 player is 512MB. He has downloaded 287MB and will continue to download m more megabytes.
Since the capacity of the player is 512MB. The used memory plus 287MB cannot be greater than 512MB, thus the inequality that shows how many more megabytes he can download are:
m + 287 ≤ 512
Solving:
m ≤ 512 - 287
m ≤ 225
Henry can download at most 225 MB more.
