A publisher claims that the average salary paid at its company is $37,500 but it could differ as much as $4500. Write and solve an absolute value inequality to determine the range of salaries at this company.|x − 37500| ≤ 4500; The salaries range from $33,000 to $42,000

|x − 37,500| ≤ 4500; The salaries are less than $33,000 or greater than $42,000.

|x − 37500| ≥ 4500; The salaries range from $33,000 to $42,000

|x − 37,500| ≥ 4500; The salaries are less than $33,000 or greater than $42,000.

Answers

In this problem, the mean salary is equal to $37,500 while the maximum salary is $4500 more than the mean and the mnimum salary is $4500 less than the mean salary. This means the equation that represents the salaries is |x − 37500| ≤ 4500; The salaries range from $33,000 to $42,000

What is 90% of 81?
X

Answers

Answer:

72.9

Step-by-step explanation:

Fractions method:

81*(90)/(100) because 90/100 is the same thing as 90%

That gives us 7290/100, from 81*90/100

Simplify: =729/10 = 72.9

Decimals method:

81*9 = 729, add in decimal and that's 72.9

Cross-multiplication:

90    100

?         81

This is read as 90 to 100, (as a ratio) so how many to 81? To solve, cross-multiply - 81*90=7290, then divide by 100 to get 72.9.

This is my first answer , hope it helped!

The cost of a watermelon depends on its weight which of the following shows this idea expressed in function notation A: weight(cost)

B: cost(watermelon)

C: cost(weight)

D: weight (watermelon)

Answers

Answer:

Option C is correct.

Step-by-step explanation:

The general form for writing a function of x is f(x) where f depends on value of x.

Here, in the given options, Option C is correct as weight is a function for cost. The cost depends on the weight. The more the weight of the watermelon, the more its cost. So, C: cost(weight) is correct.

Options B and D are irrelevant and option A is also wrong as it signifies that weight depends on cost which is wrong.

That would be choice C, cost as a function of weight.

5x-8 (4x-7)=2 solve for x

Answers

5x - 8(4x - 7) = 2

First, expand your problem. / Your problem should look like: 5x - 32x + 56 = 2
Second, simplify 5x - 32x + 56. / Your problem should look like: -27x + 56 = 2
Third, subtract 56 from both sides. / Your problem should look like: -27x = 2 - 56
Fourth, subtract 2 - 56 to get -54. / Your problem should look like: -27x = -54
Fifth, divide both sides by -27. / Your problem should look like: x = (-54)/(-27)
Sixth, simplify the fraction to - (54)/(27) / Your problem should look like: x = (54)/(27)
Seventh, simplify. / Your problem should look like: x = 2
