Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.
S:{80}
S:{15}
S:{5}
S:{−9}
Answer:
-9
Step-by-step explanation:
5(-9-4)
5(-13)
-65
4(-9+15)
4(6)
24
-65<24 so -9 is false because -65 is not smaller than 24
The solution is Option A.
The value of n which makes the inequality 5 ( n − 4 ) < 4 ( n + 15 ) false is when n = 80
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is given by
5 ( n − 4 ) < 4 ( n + 15 )
Now , on substituting the value of n as 80 in the inequality equation , we get
5 ( n − 4 ) < 4 ( n + 15 )
when n = 80
5 ( 80 - 4 ) < 4 ( 80 + 15 )
5 ( 76 ) < 4 ( 95 )
380 = 380
So , the inequality will become false as the two sides of the equation will result in value 380 when n = 80
Hence ,
The value of n = 80 in the inequality equation 5 ( n − 4 ) < 4 ( n + 15 ) will make it false

Step-by-step explanation:
Mrs Dawson buys 3 yards of lace. Since there are 36 inches in a yard, she has 3 * 36 = 108 inches of lace.
She uses 30 inches of lace for the sleeves and 30 inches of lace around the waist, for a total of 30 + 30 = 60 inches of lace used.
Subtracting the amount of lace used from the total amount of lace gives 108 - 60 = 48 inches of lace left.
Since there are 12 inches in a foot, Mrs Dawson has 48 / 12 = **4** feet of lace left.

what value of x makes this equation true -(x+3)=2(x-3)
A. 0
B. 1
C. 2
D. 3
Answer:
To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:
Step 1: Distribute the negative sign on the left side of the equation:
-(x + 3) = 2(x - 3)
=> -x - 3 = 2(x - 3) (using the distributive property)
Step 2: Expand the right side of the equation:
-x - 3 = 2x - 6
Step 3: Add x to both sides of the equation to isolate the x term on one side:
-x + x - 3 = 2x + x - 6
=> -3 = 3x - 6
Step 4: Add 6 to both sides of the equation:
-3 + 6 = 3x - 6 + 6
=> 3 = 3x
Step 5: Divide both sides of the equation by 3 to solve for x:
3/3 = 3x/3
=> 1 = x
So, the correct value of x that makes the equation true is B. 1.
PLEASE MARK BRAILYISTT :D
Answer:
B, one
Step-by-step explanation:
In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Find the area of the square rug if it is side is (7X +4) feet.
Answer:
49\(x^{2}\)+56x+16 ft squared.
Step-by-step explanation:
Alright, so we are given that we have a rug that has a side of 7x+4 feet. With this information, we are able to determine the area of the square rug. Considering that it is a square rug, all the sides are equal to each other because a square has four equal sides and angles.
To solve this, you can do it in two ways.
One, write it as (7x+4)2. That 2 is supposed to represent squared.
If you know the rule, this is a perfect square trinomial.
The formula is a squared plus 2ab plus b squared. 7 and 4 are your a and b values. 7x squared is 49x squared and 4 squared is 16.
2ab, multiply 2 times 7x times 4. That is 56x.
Therefore, the area is 49xsquared plus 56x+16.
Another way is to write it like this (7x+4) (7x+4).
Since it is an exponent, we are multiplying the same thing two times. Apply the Distributive Property.
E.G. 2(x+5)= 2x+10.
With this, you are distributing two numbers into another two numbers. 7x times 7x is 49x squared and 7x times 4 is 28x. Then, go to 4. 4 times 7x is also 28 x and 4 times 4 is 16. Now, combine the like terms. 49x squared plus 28x plus 28x or 56x plus 16.
This represents your area.
I hope this helps, and I hope you have a good day!

Mr. Abbot washed 1/4 of his laundry. His son washed 2/5 of it. Who washed most of the laundry? How much of the laundry still needs to be washed?
Answer:
Mr. Abbot washed 25% and his son washed 40% so his son washed more and 35% of it still needs to be washed
Step-by-step explanation:
7/20 of it still needs to be washed if you need it in a fraction.
35% of the laundry still needs to be done
1/4 of the laundry equates to 25%
and 2/5 equal 40%
when combined, they equal 65%
and when 65 is subtracted from 100. 35% remains to be done. 35% also equals 7/20
Write your answer as either a whole number, a reduced improper fraction, or a decimal rounded to the hundredths place.

What is the greatest number less than 400 such that 4 is the greatest common divisor of the number and 24?
Answer:
its simple greatest number less that 400 is 399
Answer:
388
Step-by-step explanation:
Definition from Wikipedia
In mathematics, the greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted as gcd(x,y) . For example, the GCD of 8 and 12 is 4, that is, gcd(8,4)=4 (https://en.wikipedia.org/wiki/Greatest_common_divisor)
Methodology to find greatest common denominator(factor) for 2 numbers
Write down the divisors of both numbersCollect the common divisors of both termsChoose the largest divisor from the above termsThe divisors of 24 are 1, 2, 3, 4, 6, 8, 12, 24Since the number is less than 400, it must be 4 x D where D < 100Let's try 4 x 99 = 396. Divisors are 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396. gcd(24, 396) = 12.Try D = 98 ==> 4 x 98 = 392 with divisors 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392. gcd(24, 392) = 8Try D = 97 ==> 4 x 97 = 388. Divisors of 388 are 1, 2, 4, 97, 194, 388 gcd(4, 388) = 4Note that even though I have listed all divisors of the higher number, you don't have to compute all divisors. You can stop figuring out the divisors once the larger number is divisible by the number that is higher than 4 but slosest to i. For example, in the case of 396, I would stop computing as soon as I found it is divisible by 6
Order these from least to greatest because I have no idea how to do it thank you

Angle 4 is congruent to angle 8. This is enough information to prove that 'u' parallel to 'v'.
What are parallel lines?For a pair of lines, the perpendicular distance is equal at every point, then the pair of lines are called parallel lines.
The given information are:
1. Angle 2 is congruent to angle 4.
Angle 2 and Angle 4 are opposite angles. They are always equal.
This information does not prove that 'u' parallel to 'v'.
2. Angle 4 is congruent to angle 8.
Angle 4 and Angle 8 are corresponding angles.
This information proves that 'u' parallel to 'v'.
Angle 6 + angle 7 = 180 degrees.
The sum of the angle 6 and angle 7 are always 180 degrees.
This information does not prove that 'u' parallel to 'v'.
Angle 3 + angle 4 = 180 degrees
The sum of the angle 6 and angle 7 are always 180 degrees.
This information does not prove that 'u' parallel to 'v'.

Part A: Write an inequality to compare the temperatures of the two cities. (3 points)
Part B: Explain what the inequality means in relation to the positions of these numbers on the number line. (4 points)
Part C: Use the number line to explain which city is warmer. (3 points)
part a: –2°F > –6°F
part b: the inequality is representing the temperatures of city R and city S, comparing the difference in their temperatures.
part c: (marking city R at –2 on the number line and marking city S at –6 on the number line), using the number line to show the values of the city temperatures, city R is warmer because it is closer to 0 while city S is farther from zero and in the case that these are negative temperatures, the temperature closest to zero is the warmest.
