Step-by-step explanation:
-8-4/x= -6
multiply x to both sides of the equation.
-8-4= -6x
solve -8-4. (-12)
-12= -6x
divide both sides by -6.
2=x
Part a: A deli receives a large order for sandwiches for a company picnic. The company wants one club sandwich and two regular sandwiches for each person. The company also wants an extra Dagwood sandwich. A club sandwich has $3$ slices of bread. A regular sandwich has $2$ slices. A Dagwood has $5$ slices. If there are $n$ people going to the company picnic, how many slices of bread does the deli need to make this order? Write your answer as a fully simplified expression. Your answer should have the variable $n$ in it exactly once. Part b: Given that the deli ends up using $110$ slices of bread, how many people are going to the company picnic?
Answer:
Um...
I know the answer to Part A, but not to Part B.
Step-by-step explanation:
The answer for Part A is 7n + 5. Hope this helps!
What is .5 ( 5 repeating) in a fraction ?
Hey there! I'm happy to help!
Let's say that our fraction is x.
x=0.5555555...
Let's get rid of the repeating stuff. If you multiplied x by 10, the fraction would be equal to 5.5555555.....
x=0.55555555....
10x=5.5555555.....
What if we subtracted the first equation from the second? Then all of the repeating stuff would be gone!
9x=5
We divide both sides by 9.
x=5/9.

Use the properties of limits to help decide whether the limit exists.find its value. limx^2 5x-36/x^2-16
Answer:
The value of limit = [tex]\frac{13}{8}[/tex]
Step-by-step explanation:
Explanation:-
Given [tex]\lim_{x \to 4} \frac{x^{2}+5 x-36 }{x^{2}-16 }[/tex]
= [tex]\lim_{x \to 4} \frac{x^{2}+9 x-4 x-36 }{(x-4)(x+4) }[/tex]
= [tex]\lim_{x \to 4} \frac{(x(x-4)+9(x-4) }{(x-4)(x+4) }[/tex]
=[tex]\lim_{x \to 4} \frac{((x-4)(x+9)}{(x-4)(x+4) }[/tex]
= [tex]\frac{4+9}{4+4}[/tex]
= [tex]\frac{13}{8}[/tex]
Hence the limit exists and The value of limit = [tex]\frac{13}{8}[/tex]

Nidhi is creating a rectangular garden in her back yard. The length of the garden is 10 feet. The perimeter of the garden must be at least 40 feet and no more than 76 feet. Write and solve a compound inequality to find the range of values for the width, w, of the garden.
Answer:
10<=w<=33
Step-by-step explanation:
length is 10 so width can only add up to 20 less than those
40-20=20
20/2=10
76-20=66
66/2=33

Solve for q in terms of m : m=2q−4/ q−5
Answer:
q = (4 - 5 m)/(2 - m)
Step-by-step explanation:
Solve for q:
m = (2 q - 4)/(q - 5)
Hint: | Reverse the equality in m = (2 q - 4)/(q - 5) in order to isolate q to the left hand side.
m = (2 q - 4)/(q - 5) is equivalent to (2 q - 4)/(q - 5) = m:
(2 q - 4)/(q - 5) = m
Hint: | Multiply both sides by a polynomial with respect to q to clear fractions.
Multiply both sides by q - 5:
2 q - 4 = m (q - 5)
Hint: | Write the linear polynomial on the right hand side in standard form.
Expand out terms of the right hand side:
2 q - 4 = m q - 5 m
Hint: | Isolate q to the left hand side.
Subtract m q - 4 from both sides:
q (2 - m) = 4 - 5 m
Hint: | Solve for q.
Divide both sides by 2 - m:
Answer: q = (4 - 5 m)/(2 - m)

The tree was 60 inches tall to use later it was 105 inches tall what is the percentage increase to the nearest hundredth of the height of the tree
Answer:
[tex]\%\ increase = 75\%[/tex]
Step-by-step explanation:
Initial Height = 60 inches
Final Height = 105 inches
Required
Determine the percentage increase
Percentage increase is calculated as thus;
[tex]\%\ increase = \frac{Final\ Height - Initial\ Height}{Initial\ Height}[/tex]
Substitute values for the final and the initial height
[tex]\%\ increase = \frac{105 - 60}{60}[/tex]
[tex]\%\ increase = \frac{45}{60}[/tex]
[tex]\%\ increase = 0.75[/tex]
Convert to percentage
[tex]\%\ increase = 75\%[/tex]
The height of the tree increased by 75%.
Given that the tree was 60 inches tall, and later it was 105 inches tall, to determine what is the percentage increase to the nearest hundredth of the height of the tree, the following cross multiplication must be performed:
60 = 100 105 = X 105 x 100/60 = X 10500/60 = X 175 = X 175 - 100 = 75Therefore, the height of the tree increased by 75%.

Center of sphere , C( 1 , -1 , 6 ) .
To Find :
Find equations of the spheres with center (1, −1, 6) that touch the following planes.a) xy-plane b) yz-plane c) xz-plane .
Solution :
a)
Distance of the point from xy-plane is :
d = 6 units .
So , equation of circle with center C and radius 6 units is :
[tex](x-1)^2+(y-(-1))^2+(z-6)^2=6^2\\\\(x-1)^2+(y+1)^2+(z-6)^2=36[/tex]
b)

Step-by-step explanation:
Angel took a 2-year lease on a new car and after 4 months of driving, he’d put 5,600 miles on it. The lease allows 10,000 miles per year. If his driving habits stay consistent, will he stay under the allotted mileage for years? By how much?
Answer:
Step-by-step explanation:
Lease years = 2 years
Allowed mileage per year = 10,000 miles
After 4 months of driving ; 5600 miles on car
If driving habit stays consistent, Angel won't stay under the alloted mileage for years,
If 4 months = 5600 miles
Average miles driven per month :
5600 / 4 = 1400 miles / month
After two years ; ( 2 × 12) = 24 months
Total miles driven :
1400 miles × 24 = 33600 miles
Total alloted miles for 2 years:
10,000 × 2 = 20,000 Miles
Excess miles driven;
20,000
Prove that root 7 is an irrational number.
Answer: Root 7 would equal 2.64575131106 and would go on forever.
Step-by-step explanation: It isn't one of the perfect squares. For example, the first 10 perfect square are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Answer:
it is an irrational number and here is why
Step-by-step explanation:
So think of square root as it's answer is something that you you multiply its self by its self and you get that answer. Ex: 8 x 8 = 64 square root of 64 is 8. So in that case there is nothing you can exactly multiply by itself to get 7 so in that case it's a decimal or an irrational number.

Solve for x: 3x+2=11
Answer:
X= 3
Step-by-step explanation:
To solve this, you must first subtract 2 from 11, to get the 3x isolated.
You'll then have 3x=9, but the x is not alone, so you subtract the 3 from both sides. This leaves you with 3
the value of x will be 3 for the given function 3x+2=11.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given a function 3x+2=11
Simplifying the function:
=> 3x + 2 = 11
subtract by 2
=> 3x +2 - 2 = 11-2
=> 3x = 9
divide by 3 into both sides
=> x = 3
Therefore, the value of x will be 3 for the given function.

Answer:
F'(x) = 2x eˣ¹⁴ − eˣ⁷
Step-by-step explanation:
You're close. According to second fundamental theorem of calculus:
If F(x) = ∫ₐᵇ f(t) dt, then F'(x) = b' f(b) − a' f(a).
F(x) = ∫ₓˣ² eᵗ⁷ dt
F'(x) = (2x) e⁽ˣ²⁾⁷ − (1) e⁽ˣ⁾⁷
F'(x) = 2x eˣ¹⁴ − eˣ⁷
