Answer:
n = 13
Step-by-step explanation:
7n + 5 = 96
Subtract 5 from both sides to get rid of the 5 on the right side:
7n + 5 - 5 = 96 - 5
7n = 91
Divide both sides by 7 to get rid of the coefficient of n:
7n / 7 = 91 / 7
n = 13
Answer: [tex]n=13[/tex]
Subtract 5 from both sides
[tex]7n+5-5=96-5\\7n=91[/tex]
Divide both sides by 7
[tex]7n/7=91/7\\x=13[/tex]

Answer:
Solution : 29
Step-by-step explanation:
As this is an equilateral triangle all sides present are congruent.
3x + 8 = 5x - 6 = 2x + 15
3x + 8 = 5x - 6
- 2x = - 14,
x = 7
And hence one side length will be say 3(7) + 8 = 21 + 8 = 29 units. We can double check this solution by substituting x for other side lengths. Remember that all the side length have an equal measure.
5(7) - 6 = 35 - 6 = 29 ✓
2(7) + 15 = 14 + 15 = 29 ✓

10. Fouster's Farms has 53 fruit trees on their land. Myrna's Farms has five
times as many fruit trees as Fouster's. A commercial farm has 500 fruit
trees. Which farm has the most fruit trees?
Answer:
myrna farm has 265 and the commercial farm 500
Step-by-step explanation:
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The farm that has the most fruit trees are commercial farm.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that Foster's Farms has 53 fruit trees on their land. Myrna's Farms has five times as many fruit trees as Foster's. Therefore, the number of trees on Myrna's farm is,
Number of trees on Myran's farm = 5 × Number of trees on Foster's farm
= 5 × 53
= 265 trees
Since the number of trees on Myran's farm and Foster's farm is 265 trees and 53 trees, respectively, while the number of trees on the commercial farm has 500 fruit trees.
Hence, The farm that has the most fruit trees are commercial farm.

d=3, A=9
d=4, A=16
It can be seen that amount earned is a square of the number of days
Therefore,
The function for the story is:

Answer:
[tex]\displaystyle \lim_{\Delta x \to 0} \frac{(x+\Delta x)^2-2(x+\Delta x)+1-(x^2-2x+1)}{\Delta x}=2x-2[/tex]
Step-by-step explanation:
We want to find the limit:
[tex]\displaystyle \lim_{\Delta x \to 0} \frac{(x+\Delta x)^2-2(x+\Delta x)+1-(x^2-2x+1)}{\Delta x}[/tex]
We can expand the numerator:
[tex]=\displaystyle \lim_{\Delta x \to 0} \frac{(x^2+2x\Delta x+\Delta x^2)+(-2x-2\Delta x)+1+(-x^2+2x-1)}{\Delta x}[/tex]
Simplify. Combine like terms:
[tex]\displaystyle \lim_{\Delta x\to 0} \frac{(x^2-x^2)+(-2x+2x)+(1-1)+(2x\Delta x+\Delta x^2-2\Delta x)}{y}[/tex]
The first three terms will cancel:
[tex]\displaystyle \lim_{\Delta x\to 0} \frac{2x\Delta x+\Delta x^2-2\Delta x}{\Delta x}[/tex]
Factor:
[tex]\displaystyle \lim_{\Delta x \to 0} \frac{\Delta x(2x+\Delta x-2)}{\Delta x}[/tex]
Cancel:
[tex]\displaystyle \lim_{\Delta x\to 0}2x+\Delta x-2[/tex]
Now, we can use direct substitution:
[tex]\displaystyle \begin{aligned} &\Rightarrow 2x+(0)-2\\ &=2x-2\end{aligned}[/tex]
Therefore:
[tex]\displaystyle \lim_{\Delta x \to 0} \frac{(x+\Delta x)^2-2(x+\Delta x)+1-(x^2-2x+1)}{\Delta x}=2x-2[/tex]
Answer:
2x-2
Step-by-step explanation:
let d = delta x
lim as d goes to 0 ( ( x+d)^2 - 2(x+d) +1 - ( x^2 -2x+1))/d
Expand the term in side the parentheses
( ( x+d)^2 - 2(x+d) +1 - ( x^2 -2x+1))
x^2 +2dx +d^2 -2x-2d+1 - x^2 +2x -1
Combine like terms
2dx +d^2 -2d
Replace
lim as d goes to 0 ( 2dx +d^2 -2d)/d
Factor out a d
lim as d goes to 0 d( 2x +d -2)/d
Cancel the d in the numerator and denominator
lim as d goes to 0 ( 2x +d -2)
Take the limit of each term as d goes to zero
2x +0-2
2x-2

Ramona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales. She sold $600 in clothing on Saturday and $1200 in clothing on Sunday. How much did she earn over the two days?
Answer: $ 532
Step-by-step explanation:
Given: Ramona works in a clothing store where she earns a base salary of $140 per day plus 14% of her daily sales.
She sold $600 in clothing on Saturday and $1200 in clothing on Sunday.
To find : Earning in two days.
Total sales she did in 2 days = $600+$1200 = $1800
Then, her total earning for 2 days = 2 x( Base salary)+ 14% of (Total sales)
= 2 x ($140) + (0.14) ($1800)
= $(280+252)
= $ 532
Hence, she earned $ 532 over the 2 days.
Answer:
$532
Step-by-step explanation:
Ramona worked for two days. So she would have already earned $280.
And she also earns 14% of $600 from the first day, and 14% of 1200.
14/100 * 600/1 = 8400/100 = $84
14/100 * 1200/1 = 16800/100 = $168
$280 + $84 + 168 = $532
Altogether, Ramona earned $532 in the total of two days! Wow that's more money then I get per month lol.

Before her shopping spree, Lemon owned 11 shirts. Then she bought some more and now she owns 33 of them. What is the ratio of shirts before the purchase to the total number of shirts after the purchase
Answer:
So the ratio of shirts before the purchase to the total number of shirts after the purchase is 1:3
Step-by-step explanation:
In this question we have to find the ratio of before and after so It will be written like this
Before : After
11: 33
Dividing both sides with 11
11/11:33/11
1: 3
So the ratio of shirts before the purchase to the total number of shirts after the purchase is 1:3
Which means that if we have total of 4 shirts then the number of shirts before the purchase were 1 and after the purchase were 4 meaning there are 3 new shirts in place for every single old shirt.

The left side continues down, and the right side continues down. C. The left side continues up, and the right side continues down. D. The left side continues down, and the right side continues up.
Answer:
A. The left side continues up, and the right side continues up.
Step-by-step explanation:
f(x) = 6x^4 + 4x^3 - 5x^2 -2x + 1
The highest power will describe the end behavior
f(x) = 6x^4
Let x = -∞
f(-∞) = 6 * (-∞)^4 = 6* ∞ = ∞
As x goes to -∞ f(x) goes to ∞
Let x = ∞
f(∞) = 6 * (∞)^4 = 6* ∞ = ∞
As x goes to ∞ f(x) goes to ∞

Traveling at 65 miles per hour how many minutes rounded to the nearest whole number does it take to drive 126 miles from San Diego to Malibu
65 miles per hour / 60 minutes per hour = 1.083 miles per minute.
126 miles/ 1.083 miles per minute = 116.03 minutes
Rounded to nearest whole number = 116 minutes.
Answer:
116 minutes
Step-by-step explanation:
speed = distance/time
speed * time = distance
time = distance/speed
time = 126 miles / 65 mph
time = 126/65 hours
time = 126/65 hours * (60 minutes)/(1 hour) = 116 minutes
What is the cost in dollars for the nails to build a fence 125 meters long if it requires 30 nails per meter? Assume that 40 nails are sold per box at a cost of $0.75 per box.
Answer: $70.50
Step-by-step explanation:
30npm x 125m = 3750 nails total
3750/40 = 93.75, meaning you will need 94 boxes to complete the fence
94x0.75= $70.50
The cost in dollars for the nails to build a fence 125 meters long will be $70.31.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
A fence is 125 meters long if it requires 30 nails per meter. Then the total number of the nail will be
⇒ 125 x 30
⇒ 3750 nails
Assume that 40 nails are sold per box. Then the total number of boxes of nail will be
⇒ 3750 / 40
⇒ 93.75 boxes
The cost of $0.75 per box. Then the total cost of nails will be
⇒ 93.75 x $0.75
⇒ $70.31
Then the cost in dollars for the nails to build a fence 125 meters long will be $70.31.
