The cost of the labor per hour will be $75 and the equation will be 505=75x+55.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the technician at the store worked on the computer for 6 hours and charged him $55 for parts. The total was $505.
The cost per hour will be calculated as below:-
505-55= 450,
This means he paid $450 total for the cost of labor. Divide 45 by 6 to get 75.
He actually paid $75/hour.
505=75x+55.
x=75
Therefore, the cost of the labor per hour will be $75 and the equation will be 505=75x+55.

Some schools call theorems and deffintions by other names, but I tried to give you the ones that are most commonly used in all schools.
Answer:
y = 90, x= 105
Step-by-step explanation:
Total number of sides = ( n-2)180
n = number of sides
(4-2)180
2× 180=360
y is a right angle triangle = 90°
x=90+90+75+x= 360
255+x=360
x= 360-255
= 105

For an experiment, the temperature of a liquid must stay above 60.7°F. The starting temperature of the liquid is 90.1°F. It is placed in a cooler, which lowers its temperature 4°F each minute. How many minutes can the liquid can stay in the cooler?
Select from the drop-down menus to correctly complete the statement. The liquid can stay in the cooler |___| minutes.
A. At most 7.35
B. At least 7.35
C. fewer than 7.35
D. more than 7.35
Answer:
The answer is C I took the k12 quiz and it said this is correct. Please mark brainliest. Thank you!!!
Step-by-step explanation:
The liquid can stay in the cooler |x≤7.35| minutes. Therefore, option A is the correct answer.
What are inequalities?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.
Given that, for an experiment, the temperature of a liquid must stay above 60.7°F.
The starting temperature of the liquid is 90.1°F.
Here, 90.1-60.7
= 29.4
It is placed in a cooler, which lowers its temperature 4°F each minute.
Now, number of minutes =29.4/4
= 7.35 minutes
Therefore, option A is the correct answer.

hey i need help solving a Krypto
numbers: 13, 16, 23, 1, 3 equals: 20
thanks in advanced :)
Theres four solutions which you wont find with most Krypto solvers since it uses .333 repeating.
The solutions are:
16 / 3 = 5.3333333333333
5.3333333333333 - 1 = 4.3333333333333
13 / 4.3333333333333 = 3
23 - 3 = 20
13 / 3 = 4.3333333333333
4.3333333333333 + 1 = 5.3333333333333
16 / 5.3333333333333 = 3
23 - 3 = 20
23 / 3 = 7.6666666666667
7.6666666666667 - 1 = 6.6666666666667
16 - 13 = 3
6.6666666666667 x 3 = 20
16 - 13 = 3
23 / 3 = 7.6666666666667
7.6666666666667 - 1 = 6.6666666666667
6.6666666666667 x 3 = 20
