8p -4p =2p+6 p= Help please
Answer:
[tex]p=3[/tex]
Step-by-step explanation:
[tex]8p-4p=2p+6[/tex]
Solve the left side:
[tex]4p=2p+6[/tex]
Subtract 2p from both sides:
[tex]4p-2p=2p+6-2p[/tex]
[tex]2p=6[/tex]
Divide both sides by 2:
[tex]\frac{2p}{2}=\frac{6}{2}[/tex]
[tex]p=3[/tex]
Answer:
p=3
Step-by-step explanation:
8p-4p=2p+6
4p=2P+6
4p-2p=6
2p=6
P=6/2
p=3 ans

Given that f(x)= k/x+1 + 6/x+2 and f(5)=8, Find the value of k.
Answer: [tex]k=\frac{300}{7}[/tex]
Step-by-step explanation:
Since we know that f(5)=8, we can plug in x=5 and set that equal to 8 to find k.
[tex]8=\frac{k}{5+1} +\frac{6}{5+2}[/tex] [add denominator]
[tex]8=\frac{k}{6} +\frac{6}{7}[/tex] [get common denominator]
[tex]8=\frac{7k}{42} +\frac{36}{42}[/tex] [add]
[tex]8=\frac{7k+36}{42}[/tex] [multiply both sides by 42]
[tex]336=7k+36[/tex] [subtract both sides by 36]
[tex]300=7k[/tex] [divide both sides by 7]
[tex]k=\frac{300}{7}[/tex]
Now, we know that [tex]k=\frac{300}{7}[/tex].

Step-by-step explanation:
It takes Dariya 35 seconds to download 5 songs from the Internet. How can the number of seconds it would take Dariya to download 7 songs at this rate be determined? ( need help )
By dividing 35 by 7.
By multiplying 35 by 7.
By finding the unit rate and dividing it by 7.
By finding the unit rate and multiplying it by 7.
To determine the number of seconds it would take Dariya to download 7 songs at the same rate, we first find the unit rate and multiply it by 7.
Hence, option 4. By finding the unit rate and multiplying it by 7 is the right option.
Unit Rate = 7second/song.
Time to download 7 songs = 49 seconds.
What do we mean by unit rate?A unit rate is a quantity taken for a unit of another quantity.
How do we solve the given question?We are given that it takes Dariya 35 seconds to download 5 songs from the Internet. We are asked about the time it will take Dariya to download y songs at the same rate.
We will first determine the unit rate of the time taken for downloading a song.
5 songs take 35 seconds.
∴ 1 song takes 35/5 = 7 seconds.
∴ Unit rate is 7seconds/song.
Now to determine the time for downloading 7 songs, we multiply the unit rate by 7.
∴ Time taken to download 7 songs = 7 songs * unit rate
or, Time taken to download 7 songs = 7 songs * 7 second/song
or, Time taken to download 7 songs = 49 seconds.
∴ To determine the number of seconds it would take Dariya to download 7 songs at the same rate, we first find the unit rate and multiply it by 7.
Hence, option 4. By finding the unit rate and multiplying it by 7 is the right option.

y = -0.5x + [?]
Answer:
The relationship between x and y is;
y = -0.5x - 4.5
Step-by-step explanation:
When x = -1, y = -4.
Thus from y = -0.5x + [?], we have;
-4 = -0.5(-1) + [?]
Let's call the question mark m for easy identification.
-4 = 0.5 + m
m = -4 - 0.5
m = - 4.5
At x = 0, y = - 4.5. Thus;
-4.5 = - 0.5(0) + m
m = -4.5
At x = 1, y = -5. Thus;
-5 = - 0.5(1) + m
-5 = - 0.5 + m
-5 + 0.5 = m
m = -4.5
We are seeing the same patter as m = - 4.5
Thus the relationship between x and y is;
y = -0.5x - 4.5
plz hellppppp (6h + 8) - (3h + 2) = 15
Answer:
h = 3
Step-by-step explanation:
Step 1: Write out equation
(6h + 8) - (3h + 2) = 15
Step 2: Distribute negative
6h + 8 - 3h - 2 = 15
Step 3: Combine like terms
3h + 6 = 15
Step 4: Subtract 6 on both sides
3h = 9
Step 5: Divide both sides by 3
h = 3
Step 6: Check Step
(6(3) + 8) - (3(3) + 2) = 15
(18 + 8) - (9 + 2) = 15
26 - 11 = 15
15 = 15
(6h + 8) - (3h + 2) = 15
Let's distribute the - to 3h + 2
6h + 8 - 3h - 2 = 15
Combine like terms
3h + 6 = 15
Subtract 6 from both sides
3h = 9
Divide both sides by 3
h = 3
A square window has an area of 1,232 in2. (a) What is the length of 1 side of the window? Round your answer to the nearest tenth. Show all of your work. (1 point for the correct answer and 1 point for showing how you got your answer)
x = length of one side.
1,232in^2 = x^2
Take the sqrt of both sides.
35.1 in = x
The length of one side = 35.1 in
Step-by-step explanation:
We know that,
area of square = a²
→ 1,232 = a²
→ a = √1232
→ a = 35.0 in
Nearest 10th = 35.1 in

Answer: The dimensions of the frame:.
W= 2√10 or about 6.3245 inches
L= 4√10 or about 12.6491 inches
Step-by-step explanation:
This would be so much easier if the area of the box was 72. Then the dimensions of the frame would be 6 × 12. So just a little bit larger and more complicated.
Here the equation is w(2w)=80
2w^2 = 80 (2w is easier to work with than L/2).
w^2=40 (^2 means squared)
√w^2 = √40 square root of both sides: Factor 40. Take out√4
W = √4*10
W= 2√10
L= 2w = 4√10
6.3245 × 12.6491 = 80

A beverage company operates two factories. Their outputs are represented by these expressions, where b is the number of bottles produce
Factory A: 2b3 – 3b2 + b - 120
Factory B: 4b2 – 3b – 260
Which polynomial represents the company's total output?
A. 6b3 – 3b2 - 3b - 140
B. 2b3 - 7b2 + 4b + 140
C 2b3 + b2 - 2b - 380
D. 6b3 – 6b2 + b + 380
Answer:
C 2b3 + b2 - 2b - 380
Step-by-step explanation:
Given:
Factory A: 2b^3 – 3b^2 + b - 120
Factory B: 4b^2 – 3b – 260
The company's total output = factory A + factory B
= (2b^3 – 3b^2 + b - 120) + (4b^2 – 3b – 260)
= 2b^3 – 3b^2 + b - 120 + 4b^2 – 3b – 260
Collect like terms
= 2b^3 – 3b^2 + 4b^2 – 3b + b - 120 - 260
= 2b^3 + b^2 - 2b - 380
C. 2b^3 + b^2 - 2b - 380
