Which of the following statements could be translated to the equation n - 5 = -2?
- A number less than five equals negative two.
- The difference between a number and five is negative two.
- If five is subtracted from a number, the result is two.
- Five less a number is equal to two.
please send help :')
Answer:
Answer would be B
Step-by-step explanation:
First, A doesnt make sense, since it isn't a ineqality.
C doesnt make sense because if 5 is subtracted form a number n, it is -2, not 2.
D doesnt work because 5 less a number (-5) is not 2, it is -2.
So B works, because the difference between n and 5 (n-5) is -2.

Which sum or difference is modeled by the algebra tiles? a. (-x2 2x 3) − (x2 − 2x − 1) = -2x2 2 b. (-x2 2x 3) − (-x2 2x 1) = -2x2 2 c. (-x2 2x 3) (-x2 2x 1) = -2x2 2 d. (-x2 2x 3) (-x2 − 2x − 1) = -2x2 2
The sum or difference modeled by the algebraic tiles is (-x²+2x+3) + (-x²-2x-1) = -2x²+2
How to determine the sum or difference?From the complete question, we have the following expressions:
(-x²+2x+3) and (-x²-2x-1)
Add both expressions
(-x²+2x+3) + (-x²-2x-1)
Expand
-x²+2x+3 -x²-2x-1
Collect the like terms
-x² -x² + 2x - 2x + 3 -1
Evaluate the like terms
-2x²+2
Hence, the sum or difference modeled by the algebraic tiles is (-x²+2x+3) + (-x²-2x-1) = -2x²+2

What is unit conversion?
The process of converting the unit form is known as the unit conversion.
For example, in the SI unit system, distance is in meter while in CGS, it is represented in cm.
Given that:
2 inch = 1.5 feet
1 inch = [tex]\frac{1.5}{2}[/tex]
then, 8 inches =[tex]\frac{1.5}{2} *8[/tex]
= 1.5*4

You have been given data about gas prices in 15 states.
2018 Gas Price Data
Max: $2.42
Min: $2.03
Mean: $2.098
Median: $2.06
Mode: $2.04
Variance: 0.0121
Standard Deviation: $0.1098
What is the range of the data for the 2018 data?
Range = maximum value - minimum value
The range is $0.39 which is the difference of the max value and min value.
What is the median?A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.
We have data given:
Max: $2.42
Min: $2.03
Mean: $2.098
Median: $2.06
Mode: $2.04
Variance: 0.0121
As we know, the range = Max value—Min value
Here, Max = $2.42
Min = $2.03
Range = 2.42 - 2.03 = $0.39
Thus, the range is $0.39 which is the difference of the max value and min value.

One week, kevin earned $492.00 at his job when he worked for 20 hours. if he is paid the same hourly wage, how much would he make the next week if he worked 3 hours?
Answer:
$73.80
Step-by-step explanation:
First we will find Kevin's hourly wage. We can do this by dividing his total pay by the number of hours he worked.
$492 / 20 hours = $24.60/hour
Now we can find how much he will make the next week.
$24.60/hour * 3 hours = $73.80.

Which expression is not equivalent to the other three?
Explanation:
Choice A simplifies to 9n-8 after combining the like terms -7n+16n to get 9n
Choice C simplifies to 9n-8 for similar reasoning. The n+8n turns into 9n
This shows choices A and C are equivalent to choice D. Choice B isn't the same because 9(n-8) = 9n-9*8 = 9n-72. Use the distributive property.
Answer:
B. 9(n - 8)
Step-by-step explanation:
- 8 - 7n + 16n
-8 (-7n + 16n or 16n - 7n)
-8 + 9n
9n - 8
9(n - 8)
9n - 72
n - 8 + 8n

A percentage is a way to describe a part of a whole. The percentage of 4c that is equal to 0.04c is 1%.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The percentage of 4c that is equal to 0.04c can be found as,
x% of 4c = 0.04
(x/100) × 4c = 0.04
[tex]x = \dfrac{0.04c \times 100}{4c}[/tex]
x = 1%

In 2014 the population of Kenya was estimated to be 45,121,040 with a growth rate of 2.7%. Question 1 Use the exponential growth formula to write an equation that estimates the population y in terms of the time t. Enter your answer in the box. Then apply the exponential growth formula to estimate the population of Kenya in 2020. Round to the nearest whole number
Answer:
y = 45,121,040×1.027^t
Step-by-step explanation:
An exponential growth equation is generally of the form ...
value at time t = (initial value)(growth factor)^t
where the growth factor is the multiplier for a period equal to one time unit.
Here, the initial value (in 2014) is 45,121,040. The growth factor is given as 1.027 (2.7% added per year), and we can define t as the number of years after 2014. Then our equation is ...
y = 45,121,040×1.027^t . . . . where t = years after 2014
