What is an expression?

Expression in mathematics is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Let the two numbers be x and y respectively. Now let corelate the statement given in question :

One positive number is 1/5 of another number which  means x=(1/5) y

and, it is also given that the difference between the two numbers is 60 which means y -x = 60. Now solving these question by substitution method.

y-x = 60

5x-x= 60

4x = 60

x = 15

y = 75

Therefore, the two positive numbers are 15 and 75 respectively.

Find a parametric representation of the solution set of the linear equation. (enter your answer as a comma-separated list of equations. use s and t as your parameters.) x + y + z = 2

Answers

Final answer:

The parametric representation of the solution set for the equation x + y + z = 2 is x = t, y = 2 - s - t, z = s, with 's' and 't' as the parameters.

Explanation:

To find the parametric representation of the solution set of the linear equation x + y + z = 2, we first need to express two variables in terms of the third. Let's use 's' and 't' as parameters.

We can express x and y in terms of z. Let's express z as 's'. So, z = s.

The equation x + y + z = 2 thus becomes x + y = 2 - s. We can choose x = t and y = 2 - s - t.

So, the parametric representation of the solution set for the given linear equation is (x = t, y = 2 - s - t, z = s), where 's' and 't' are parameters that can assume any real value.

Country A produces about eight times the amount of diamonds in carats produced in country B. If the total produced in both countries is 9,000,000 carats, find the amount produced in each country

Answers

that would be 9,000,000,000 times 8, wich is 72,000,000,000. Because 9*8 is 72 excepts theres a 9 million.
Let X = # carats produced in country B.
Then A + B = 8B + B = 9000000  9B = 9000000
B = 1000000

Answers

She can be late 7 days max

Answer:

7 days

Step-by-step explanation:

Given: Ms. Ache is paid $1250 per week but it's fined $100 each day she is late to work.

To Find: maximum number of days she can be late to work and still reach her goal of making at least $3000?

Solution:

per week payment of Ms. Ache =[tex]\$[/tex] [tex]1250[/tex]

Fine for getting late a day =     [tex]\$[/tex] [tex]100[/tex]

let number of days Ms. Ache gets late =  [tex]\text{x}[/tex]

Amount Ms. Ache wants to make in three weeks = [tex]\$[/tex] [tex]3000[/tex]

maximum earning potential of Ms. Ache in 3 weeks = [tex]1250\times3[/tex]= [tex]\$[/tex] [tex]3750[/tex]

ymnast Clothing manufactures expensive soccer cleats for sale to college bookstores in runs of up to 500. Its cost (in dollars) for a run of x pairs of cleats is
C(x) = 3250 + 5x + 0.1x2 (0 ≤ x ≤ 500).
Gymnast Clothing sells the cleats at $110 per pair. Find the revenue and profit functions. How many should Gymnast Clothing manufacture to make a profit?

Answers

The relationship between profit and revenue is:

Profit = Revenue - Total Cost
Since the cost is given as a function, the equation will be substituted as
Profit = Revenue - (3,250 + 5x + 0.1x²)

Now, the revenue is a linear graph because it is the number of pairs multiplied the fixed rate. So, the slope is constant. 
Revenue = 110x --> this is the function for revenue
Thus, the equation for profit would be

Profit = 110x - 3,250 - 5x - 0.1x²
P = -0.1x²+105x-3,250  --> this is the function for profit

Now, to find the minimum value of x to make profit, differentiate P with respect to x and equate to 0.

dP/dx = 0 = -0.2x + 105
x = 525

Thus, the Gymnast Clothing should manufacture at least 525 pairs in order to make profit.

So is the answer - least is the negative first, them zero, them the positive?

Answers

its just a matter of subbing....and for it to be a solution, it has to satisfy both inequalities.

-4 < = -2 + 2
-4 < = 0 (true)

y > = x - 3.....(-2,-4)...x = -2 and y = -4
-4 > = -2 - 3
-4 > = -5 (true)

ur answer is the last one


The given ordered pair is the solution of y ≤ x + 2 and y ≥ x - 3. Option E is correct.

As of the given numeral, The ordered pair (–2, –4) is a solution of which system is to be determined.

What is inequality?

Inequality is defined as the relationship of an equation containing the symbol ( ≤, ≥, <, >) instead of the equal sign.

here,
(–2, –4) is a solution of y ≤ x + 2 and y ≥ x - 3,
Proof,
Substitute this ordered paired in the inequality,

-4 ≤ -2 + 2

what is The cost per unit?

Answers

The cost per unit is the total expenditure incurred by a company to produce, store and sell one unit of a particular product or service. Unit costs include all fixed costs, and all variable costs, involved in production.

To figure your total manufacturing cost per unit, divide your total costs by the total number of units produced. For example, say for the year your company made 1 million units and incurred production costs of $3 million. Divide your $3 million costs by the 1 million units to find your cost per unit: $3.
