Answer:
n = - [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Given
- 5(n - 1) = 7(n + 3) ← distribute parenthesis on both sides
- 5n + 5 = 7n + 21 ( subtract 7n from both sides )
- 12n + 5 = 21 ( subtract 5 from both sides )
- 12n = 16 ( divide both sides by - 12 )
n = [tex]\frac{16}{-12}[/tex] = - [tex]\frac{4}{3}[/tex]
Answer:
Step-by-step explanation:
To solve this you have to use the distributive property.
So first you would distribute the -5 to n and -1.
So the new equation will be -5n + 1 = 7 (n + 3)
Next, distribute the 7 to n and 3.
The new equation will be -5n + 1 = 7n + 21
Next you simplify by adding 5n to both sides which will give you 1 = 12n + 21
Then you subtract 21 from both sides and get -20 = 12n
So then you divide both sides by 12 to get n by itself and you are left with -5/3 = n

A 20 foot ladder is placed against a wall at a 75 degree angle with the ground. The wall is perpendicular to the ground.
PART A: How high on the wall, in feet, will the ladder reach? Round your answer to the nearest tenth. Show your work.
PART B: What is the distance, in feet, from the wall to the base of the ladder? Show your work.
Answer:
Part A)
Height = 19.3 feet
Part B)
Distance = 5.2 feet
Step-by-step explanation:
Part A)
Let ladder reaches upto the h height of the wall.
[tex] \therefore \sin \theta =\frac{h}{length\: of\: the \:ladder} [/tex]
[tex] \therefore \sin 75\degree =\frac{h}{20} [/tex]
[tex] \therefore 0.9659258263 =\frac{h}{20} [/tex]
[tex] \therefore 0.9659258263\times 20 = h [/tex]
[tex] \therefore 19.3185165 \: ft= h [/tex]
[tex] \therefore h = 19.3 \: ft= h [/tex]
Part B)
Let the distance from the wall to the base of the ladder be x feet.
[tex] \therefore \cos \theta =\frac{x}{length\: of\: the \:ladder} [/tex]
[tex] \therefore \cos 75\degree =\frac{x}{20} [/tex]
[tex] \therefore 0.2588190451 =\frac{x}{20} [/tex]
[tex] \therefore 0.2588190451\times 20 = x [/tex]
[tex] \therefore 5.1763809 \: ft= x [/tex]
[tex] \therefore x = 5.2 \: ft [/tex]

Bens living room is a rectangle measuring 9 yards by 150 inches. By how many feet does the length of the room exceed the width?
Answer:
14.5 ft or 14 1/2 ft
Step-by-step explanation:
36in= 1 yard
9x36= 324in (I'm guessing this is the length)
324in (length) -150in (width)= 174in
12 in= 1 ft
174/12= 14 ft 6 in
6 inches is half a foot
14.5 ft or 14 1/2 ft

10 builders can build a house in 20 days. How many builders
will you need build the house in 10 days?
Answer:
20 builders
Step-by-step explanation:
Answer: 20 builders.
Step-by-step explanation: For 10 builders to build a house in 20 days, the ratio is 1:2. For builders to build a house in 10 days, the ratio is x:10. You then cross multiply 1:2 and x:10. Then x=20 so 20 builders.

Answer:
m = 1 and b = 5/7
Step-by-step explanation:
Take two of the points. The first two. (7, 5) and (8, 6).
We can find the slope using:
y2-y1/x2-x1
We can sub in the values:
6-5/8-7 = 1/1 = 1
So the slope is 1
now, putting this into y=mx+b, and using one of the coordinates from earlier, we can solve for b:
5 = (1)(7) + b
b = 5/7
Therefore, m = 1 and b = 5/7
Hope this helps!

Find the median of 1.4, 0.9, 2.4, 3.5, 2
Step-by-step explanation:
We arrange the numbers in increasing order:
0.9, 1.4, 2, 2.4, 3.5
Since there are five terms, the median is the third term, which is 2.
The median of the given data set is 2.
What is a median?The median is the middle number in a sorted, ascending or descending list of numbers.
Given is a data set, 1.4, 0.9, 2.4, 3.5, 2, we need to find median,
Rearranging the data from lowest to greatest,
0.9, 1.4, 2, 2.4, 3.5
Since, the median is the middle most value in a data, therefore, the middle most value of the given data is 2.
Therefore, we can say the median is 2.
Hence, the median of the data is 2.
