The number 18 is 2/3 of the number 27.
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 18 is 2/3 rd of the number. The value of the unknown number will be calculated as,
2 / 3 x = 18
x = ( 18 x 3 ) / 2
x = 9 x 3
x = 27
Therefore, the unknown number will be 27.

w−2+2w=6+5w please helppp
The solution to the equation W - 2 + 2w = 6 + 5w is W = -4.
To solve the equation W - 2 + 2w = 6 + 5w, follow these steps:
Begin by gathering the terms with W on one side and the terms without W on the other side of the equation.
Start by subtracting 2w from both sides:
W - 2 + 2w - 2w = 6 + 5w - 2w
Simplify:
W - 2 = 6 + 3w
Next, move the constant term (6) to the left side by subtracting 6 from both sides:
W - 2 - 6 = 6 + 3w - 6
Simplify:
W - 8 = 3w
Now, let's isolate the variable W by subtracting 3w from both sides:
W - 3w - 8 = 3w - 3w
Simplify:
-2w - 8 = 0
Finally, solve for W by adding 8 to both sides:
-2w - 8 + 8 = 0 + 8
Simplify:
-2w = 8
Divide both sides by -2 to isolate w:
(-2w) / -2 = 8 / -2
Simplify:
w = -4

To set this ratio up, you would put $6 over 18lbs is equal to x over 3lbs.
Next, multiply $6 and 3lbs to give you 18.
Finally, divide 18 by 18 to give you a final answer of $1. Hope this helps!
How to identify the parent function given an equation ?
Answer:
You can identify the parent function by making the equation into its simplest form.
Step-by-step explanation:
Remove all transformations from the equation (such as plus/minus signs, constants, and extra terms in the equation).
ex. y= -3x^2+15
The parent function would be y=x^2 after removing everything.
Hope this helps! :)
Bob and Carl each rented the same kind of moving truck from EZ Move. There was a flat rental fee plus a charge per mile that the truck was driven. Bob's cost for his truck was $112.96 for 138 miles. Carl's cost for his truck was $142.78 for 209 miles. Which equation can be used to represent the cost of the rental truck? Round to the nearest hundredth if necessary. y = 71 x minus 29.82 y = 25 x minus 66 y = 0.42 x + 71 y = 0.42 x + 55
Answer:
D. y = 0.42x + 55
Step-by-step explanation:
Let the equation for the cost of the truck be represented by y = mx + b,
where y = cost of truck per mile, x = number of miles, m = charge of the truck per mile and b = rental fee.
We are given that,
Cost for Bob's truck ( y ) = $112.96 for x = 138 miles, and
Cost for Carl's truck ( y ) = $142.78 for x = 209 miles.
This gives us the equations,
142.78 = 209m + b
112.96 = 138m + b
Subtracting these equations, we get,
29.82 = 71m
i.e. m = 0.42
Substituting the value of ' m ' in first equation, we get,
142.78 = 209 × 0.42 + b
i.e. 142.78 = 87.78 + b
i.e. b = 55.
Hence, the equation for the cost of the truck is y = 0.42x + 55
Answer:
d.y = 0.42 x + 55

The temperature in some region of Alaska equals 12° F. Convert this temperature to Celsius.
12°F='c (Round to the nearest tenth of a degree as needed.)
Answer:
-11.1
12°F= -11.1°C
Sorry if I'm late to answering..
The temperature of Alaska in degree celsius will be -11.11°C.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
For example, kilo gram to gram.
Given the temperature of Alaska 12° F.
Since we know,
°C = 5/9(°F - 32)
Given that.
°F → 12°F
So,
°C = 5/9(12 - 32)
°C = 5/9(-20)
°C = -11.11
Hence "The temperature of Alaska in degree celsius will be -11.11°C".

Step-by-step explanation:
Please help due tonight very urgent being graded need help please Tom makes $25 an hour working at the local video game store. Over the past year he has saved $150 toward a new iPhone. If the iPhone cost $300, how many hours will he need to work to be able to buy the iPhone? make an equation or inequality and solve. Show your work
Hey there! I'm happy to help!
Tom has 150 already saved and for every hour he works, he will gain an extra $25. After h hours, he will have $300,
So, we multiply 25 by n, because for every hour he will have 25 added to his total, and repeated addition is multiplication, so we multiply 25 by n.
We add 150 as that is what we already have saved.
Finally, we want this to equal 300.
So, here is our equation.
25n+150=300
Now we solve. We subtract 150 from both sides.
25n=150
We divide both sides by 25.
n=6
Tom will have to work six hours to buy the iPhone.
Have a wonderful day! :D
Answer:
25(6)+150=300
Step-by-step explanation:
25x+150=300
