Given the inequality 5(n − 4) < 4(n + 15), determine which integer makes the inequality false.

S:{80}
S:{15}
S:{5}
S:{−9}

Answers

Answer 1

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

Answer 2

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

The graph shows the number of quarts picked and the amount of money the customer paid.
Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this????

Answers

Answer:

2.5, 8.75

Step-by-step explanation:

The answer is (2.5, 8.75).

Explanation: First you want to find the unit rate. So if you look at the graph you see that one quart is equal to 3.5 dollars. This is your unit rate.

Next, do $8.75/$3.5. You want to divide because since you know the unit rate is 3.5, you want to find how much u have to multiply to get to 8.75. 8.75/3.5 is 2.5. Finally you want to find the quarts the customer bought so you do 2.5 x 1 since you increased by x2.5. If you put these two answers together on a graph you get (2.5, 8.75)

English is not my first language so I apologize if my answer is hard to understand.

The graph shows the number of quarts picked and the amount of money the customer paid.


Another customer pays $8.75 for the strawberries she picks. What point (n, a) on the graph represents this?

Answers

Answer:

The point would be (2.5,8.75)

Because we know the customer paid $8.75, we use the y-axis to find this point. Then we'll find where the line meets 8.75 on the y-axis. This is at 2.5. We know that points are in the order of (x,y) therefore the point is (2.5,8.75)

this is more or less of how your graph should look like, based off of the price ($8.75), your y-axis should go up to 8.75 or 8 3/4 and the x axis meets at around 2 1/2

Answer:

-2/3

Step-by-step explanation:

You are looking the change in y over  the change in x.

for y, if you go from -5 to -7, how much did it change?  -2

-7 -(-5) = -7 + 5 = -2

Now look the the x's.  If you from 6 to 9 how much did you change?

3

9-6 = 3

-2/3

Answer:

-2/3

Step-by-step explanation:

A slope is [tex]\frac{Change in Y}{Change in X}[/tex] and we can see that when the x value increases by 3, the y value decreases by 2. So if we plug that in, we get -2 for the Change in Y and +3 for the Change in X. Which results in the slope being [tex]-\frac{2}{3}[/tex]

Pamela is 8 years older than Jiri. The sum of their ages is 62. What is Jiri's age?

Answers

Answer:

Jiri's age = 27

Step-by-step explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer:

Jiri is 27 years old.

Step-by-step explanation:

Step 1: Declare variables

Let Jiri’s age be [tex]\displaystyle x[/tex] years old.

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is [tex]\displaystyle{8+x}[/tex] years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of [tex]\displaystyle{x+8+x=62}[/tex] (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

[tex]\displaystyle{2x+8=62}[/tex]

Step 4: Subtract both sides by 8

[tex]\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}[/tex]

Step 5: Divide both sides by 2

[tex]\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}[/tex]

Since Jiri’s age is defined as [tex]x[/tex] years old. Therefore, Jiri’s age is 27 years old.

Because we’re given 4 Ws and told that they add to 20, we can simply divide 20 by 4 to find that each W value is equal to 5 (5+5+5+5=20).
We can then use our new found information for w+w+x+x = 24. We know that W = 5, so: 5+5+x+x = 24, and then 10+2x (because there were two Xs (if it was x+x+x, it would be 3x)) so, 10+2x=24, we can subtract 10 from both sides to get 2x by itself:
2x=24-10,
2x=14,
Then to get X by itself, we can divide by 2 on both sides:
2x/2 = 14/2
x=7
So now we know X’s value, X=7
