10. Solve: 3( 3x + 1)-(4x + 1) = 6x - 3(x+4)
Can’t solve this, any suggestions?
Answer:-7
Step-by-step explanation:Let's solve your equation step-by-step.
3(3x+1)−(4x+1)=6x−3(x+4)
Step 1: Simplify both sides of the equation.
3(3x+1)−(4x+1)=6x−3(x+4)
3(3x+1)+−1(4x+1)=6x−3(x+4)(Distribute the Negative Sign)
3(3x+1)+−1(4x)+(−1)(1)=6x−3(x+4)
3(3x+1)+−4x+−1=6x−3(x+4)
(3)(3x)+(3)(1)+−4x+−1=6x+(−3)(x)+(−3)(4)(Distribute)
9x+3+−4x+−1=6x+−3x+−12
(9x+−4x)+(3+−1)=(6x+−3x)+(−12)(Combine Like Terms)
5x+2=3x+−12
5x+2=3x−12
Step 2: Subtract 3x from both sides.
5x+2−3x=3x−12−3x
2x+2=−12
Step 3: Subtract 2 from both sides.
2x+2−2=−12−2
2x=−14
Step 4: Divide both sides by 2.
2x /2
=
−14 /2
x=−7
Steven earns extra money babysitting. He charges $25.00 for 4 hours and $43.75 for 7 hours.
Enter an equation to represent the relationship. Let x represent the number of hours Steven babysits and y represent the amount he charges.
Answer:
An easy way to solve this problem is divide $25.00 by 3 or $43.75 by 7. This number represents the amount of money he makes for 1 hour. So with that in mind, the correct equation is:
$8.33 = y

A Karate club consists of 35 persons holding a black belt
(highest rating), 64 persons holding a brown belt (middle
rating), and 97 persons holding a purple belt (lowest rating).
What is the probability that a randomly-selected club member
holds a brown belt or a purple belt?
A) 0.238
B) 0.762
C) 0.687
D) 0.313
Answer:
B
Step-by-step explanation:
35+64+97=196 97+64=161 161/196=B
The probability that a randomly-selected club member holds a brown belt or a purple belt is 0.821 which is nearest to 0.762.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of person = 35+64+97 = 196
P(brown belt) = 64/196
P(purple belt) = 97/196
Probability that a randomly-selected club member holds a brown belt or a purple belt:
= 64/196 + 97/196
= (64+97)/196
= 161/196 = 0.821
Thus, the probability that a randomly-selected club member holds a brown belt or a purple belt is 0.821 which is nearest to 0.762.

Three partners are investing a total of $700,000 to open a garden and landscaping store. The first partner wns 30% of the business, and the second partner owns 25% of the business. What percent does the third partner own? Just input the numerals for your answer -do not add a percent sign. hip
Answer: 45
Step-by-step explanation: The 3rd partner has 45% of the store. Which is also $315,000.
Answer: the third partner owns 45% or $315,000 of the business.
Step-by-step explanation:
30 percent of 700,000=210,00
25 percent of 700,000=175,000
175,000+210,000=385,000
700,000-385,000= 315,000
the third partner owns 315,000 and 315,000=45%
Solve the equation
Y = -2(x+4) + 6 when x = -2 then use that value of y to evalute w = -3 - 2y
Answer:
12
Step-by-step explanation:
Plug in for x first:
Y = -2(x+4) +6
Y = -2((-2)+4) +6
Y = -4 + 6
Y = 2
Then use Y to find W;
W = -3 -2y
W = -3 - 2(2)
W = -3(-4)
W= 12
Answer:
y=8 and w=13
Step-by-step explanation:
y=-2(x+4)
-2x-2=4 sooo...
y=4+4
y=8
then plug 8 into the equation for w
w=-3-2y
then you would get
w=-3-16
-3-16
w=13

Are 18:3 and 6:1 equivalent radios?
Answer:
Yes
Step-by-step explanation
6:3 multiply by 3 is equal to 18:3
Answer:
Yes
Step-by-step explanation:
This is because 6x3 is 18 for the 18:3 and 1x3 is 3 in the 18:3. You can also think it this way, 18/3 and 6/1 if you divide both you get an answer of 6 so they both are the same meaning making them equivalent
Maximize B=XY^2 , where x and y are positive numbers such that X+Y^2=5.
Without using any calculus:
If x + y² = 5, then y² = 5 - x, so that
b = x y² = x (5 - x) = 5 x - x²
Complete the square to get
b = 25/4 - (x - 5/2)²
Then b gets a maximum value of 25/4 when x = 5/2.
Simple calculus method:
With b = 5 x - x², differentiate b with respect to x and set the derivative equal to 0 to solve for critical points:
db/dx = 5 - 2 x = 0 ==> x = 5/2
Take the second derivative to determine whether b is concave or convex:
d²b/dx² = -2
The second derivative is negative, which means b is concave with respect to x, and this indicates x = 5/2 is the site of a local maximum, which is b (5/2) = 25/4.
More complicated calculus method:
Lagrange multipliers. The Lagrangian is
L (x, y, λ) = x y² - λ (x + y² - 5)
where we assume λ ≠ 0.
Take its derivatives:
dL/dx = y² - λ
dL/dy = 2 x y - 2 λ y
dL/dλ = x + y² - 5
Set each derivative equal to 0 to find the critical points. The first equation tells us y² = λ, and the second equation tells us x = λ, so
x + y² - 5 = 2 λ - 5 = 0
Solving this gives λ = x = y² = 5/2, so that b has an extreme value of
b = (5/2) (5/2) = 25/4
Deciding whether this is a maximum or minimum comes down to computing the Hessian determinant at the critical value. The Hessian is
[tex]H(x,y)=\begin{bmatrix}\dfrac{\partial^2b}{\partial x^2}&\dfrac{\partial^2b}{\partial x\partial y}\\\\\dfrac{\partial^2b}{\partial y\partial x}&\dfrac{\partial^2b}{\partial y^2}\end{bmatrix}=\begin{bmatrix}0&2y\\2y&2x\end{bmatrix}[/tex]
with determinant |H (x, y)| = -4 y². At the critical point, the determinant is -10 < 0, which indicates a maximum value of 25/4.
Netlfix charges $30 a month plus $5 per movie. Hulu charges $26 a month plus $ per movie. How many movies will you need to watch for the Netflix membership to pay off and cost you less?
The question is incomplete:
Netlfix charges $30 a month plus $5 per movie. Hulu charges $26 a month plus $7 per movie. How many movies will you need to watch for the Netflix membership to pay off and cost you less?
Answer:
3 movies
Step-by-step explanation:
From the information given, you can write an inequality that indicates that Netflix membership costs less than Hulu membership:
30+5x<26+7x
Now, you can solve for x:
30-26<7x-5x
4<2x
4/2<x
x>2
According to this, the answer is that you will need to watch 3 movies for the Netflix membership to pay off and cost you less.

The two-way table below describes the car rental habits of sales representatives attending a conference.
What percentage of representatives staying at least two nights rented a car?
20%
44%
55%
79%
Answer:
44 bro
Step-by-step explanation:
The percentage of representatives staying at least two nights rented a car is 44%.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
So the percentage actually means a part per 100.
Percentage is usually denoted by the symbol '%'.
Given is a two way table.
From the table, the number of representatives staying at least 2 nights rented a car is 11.
Total number of representatives staying at least two nights = 14 + 11 = 25
Percentage = (11 / 25) × 100
= 0.44 × 100
= 44%
Hence the percentage for the required number is 44%.

Answer:
700,000
Step-by-step explanation:
Well, [tex]10^{4}[/tex] as we know is 10(10)(10)(10), or 10 multiplied by itself 4 times.
The easiest way to solve this, is knowing that because 10 is being multiplied by itself 4 times, it'll have the outcome of 10000, which has 4 zeroes. This is very good to remember, so I recommend remembering it :) Just like if the question was about [tex]10^{5}[/tex], it would be 100000, which has 5 zeroes.
So now we add on all of those zeroes to 70.
700000 would be your answer because we added on 4 more zeroes.
