Answer:
we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
Step-by-step explanation:
We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".
In other words, it is symbolically represented as:
' ~q ~p is the contrapositive of p q '
For example, the contrapositive of "If it is a rainy day, then they suspend the match" is "If they do not suspend the match, then it won't be a rainy day."
Given
p: 2x -5=5
q: 4x-6=14
As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p
Thus, we conclude that:
If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
Evaluate the expression below
if a = -8, b = 17, and c = 21
a2 –(b+c)
Answer:
-54
Step-by-step explanation:
first fill in the numbers
next do the parentheses 17 + 21=38
then find -8×2 which equals -16
then subtract -16 from 38 and get -54
The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.
What is the value of the expression?When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
The expression is given below.
⇒ a² - (b + c)
The value of the expression at a = -8, b = 17, and c = 21 will be
⇒ a² - (b + c)
⇒ (-8)² - (17 + 21)
⇒ 64 - 38
⇒ 26
The value of the expression a² - (b + c) at a = -8, b = 17, and c = 21 will be 26.

Don has two jobs. For Job 1, he earns $7.55 an hour. For Job 2, he earns $8.45 an hour. Last week he worked at the first job for 10 hours and at the second job for 15 hours. What were his average earnings per hour? a $8.15 b $8.13 c $8.00 d $8.09
Answer:
D. $8.09
Step-by-step explanation:
Get the total amount for Job 1 & Job 2 he worked for x amount of hours. The x amount of hours and the amount of earnings he get per hour is given to us:
Job 1: $7.55 x 10 = $75.50
Job 2: $8.45 x 15 = $126.75
Add two total costs from work:
$75.50 + $126.75 = $202.25
You add 10 + 15 to get 25 and we need this number for the average as he worked 25 hours in total:
$202.25 / 25 = $8.09 per hour
Don's average earnings per hour is $8.09 per hour.

use the function g (x) = √x-5 for the problem below which is what are the values of x for which g(x)=6?
Answer:
x = 121
Step-by-step explanation:
We are given;
g(x) = √x - 5
Now, we are told that g(x) = 6
Thus;
√x - 5 = 6
Add 5 to both sides to get;
√x = 11
Square both sides to get;
x = 121

O 6x?y and 4x® y5
O 10x®y 15 and 14x®y 15
O 9x4y11 and 12x2y4
Answer:
The length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]
Option A is correct.
Step-by-step explanation:
We are given: [tex]Area\:of\:rectangle=Length\times Width[/tex]
if [tex]Area = 24x^6y^{15}[/tex]we need to find the length and width of rectangle from options given.
Looking at the options, Option B,C and D are incorrect because multiplying the given lengths and widths, the area is not equal to [tex]24x^6y^{15}[/tex]
Only Option A gives us the result i,e
[tex]Area=2x^5y^8\times 12xy^7\\Area=24x^6y^{15}[/tex]
So, the length and width of the rectangle are: [tex]\mathbf{2x^5y^8\:and\: 12xy^7}[/tex]

100% = ?
cross multiply
62.5
Her original score was 62.5
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here, her new score as 75 then let his original score be x
then 75 = (1+20%) × x
x= 75/1.2
= 62.5
Hence, the original score is 62.5
