if the cost of 3 pies is $20.What is the cost for 6 pies

Answer:

(1,7)

Step-by-step explanation:

You are given the system of two equations

[tex]\left\{\begin{array}{l}x-y=-6\\5x+3y=24\end{array}\right..[/tex]

Each equation represents straight line in the diagram. The point of intersection between these two lines represents the solution of the system of two equations. From the diagram  the best approximation of the solution of the system rounded to the nearest whole number is (1,7).

Or you can solve this system algebraically. Express x from the first equation

[tex]x=y-6[/tex]

and substitute it into the second equation:

[tex]5(y-6)+3y=24,\\ \\5y-30+3y=24,\\ \\8y=54,\\ \\y=\dfrac{54}{8}=\dfrac{27}{4}=6.75\approx 7.[/tex]

Then

[tex]x=6.75-6=0.75\approx 1.[/tex]

The equation in standard form that represents the relationship between Fahrenheit (F) and Celsius (C) is 5F + (5/9)(F - 32) = 39.

In order to represent the relationship between Fahrenheit (F) and Celsius (C) in standard form, we can use the conversion formula:

C = (5/9)(F - 32)

Given the equation 5F + C = 39, we can substitute the value of C from the conversion formula into the equation:

5F + (5/9)(F - 32) = 39

Simplifying the equation further:

45F + 5(F - 32) = 351

45F + 5F - 160 = 351

Combine like terms:

50F - 160 = 351

Add 160 to both sides:

50F = 511

Divide both sides by 50:

F = 10.22

Therefore, the equation in standard form that represents the relationship between F (degrees Fahrenheit) and C (degrees Celsius) is 5F + (5/9)(F - 32) = 39.

Answer,

Explanation,

So, basicly they want you to put the numbers (1/5) & (15) in place of the letters (c) & (d). Let's do that,

5 * 1/5 + 1/5 * 15

So, now that we have replaced the letters with numbers we simply simplify,

5 * 1/5 = 1

1/5 * 15 = 3

3 + 1 = 4

Hope this helps :-)

The simplified expression of the expression (0.07b³m + 7) ÷ (15bm⁻¹) is (0.07b³m + 7) ÷ (15bm⁻¹)

To simplify the expression, we have

The GCD of the numerator and denominator is 1.

So, the simplified expression is:

(0.07b³m + 7) ÷ (15bm⁻¹) = (0.07b³m + 7) ÷ (15bm⁻¹)

Step-by-step explanation:

the n th term of an arithmetic sequence is

[tex]t_{n}[/tex] = [tex]t_{1}[/tex] + (n - 1)d

given [tex]t_{1}[/tex] = 3 and [tex]t_{2}[/tex] = 10, then

[tex]t_{2}[/tex] = 3 + d = 10 ⇒ d = 10 - 3 = 7

[tex]t_{n}[/tex] = 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][2[tex]t_{1}[/tex] + (n - 1)d ]

                        = [tex]\frac{n}{2}[/tex][(2 × 3) + 7(n - 1) ]

                        = [tex]\frac{n}{2}[/tex](6 + 7n - 7 )

                        = [tex]\frac{n}{2}[/tex](7n - 1)

Answer:

-3 degrees per hour

Step-by-step explanation:

Temperature was [tex]0[/tex] degrees and it fell to [tex]-6\frac{3}{5}=-\frac{33}{5}[/tex] in [tex]2\frac{1}{5}=\frac{11}{5}[/tex] hours.

To get temperature change per hour, we divide the change by total number of hours. So:

So temperature changer per hour:

[tex]\frac{-\frac{33}{5}}{\frac{11}{5}}\\=-\frac{33}{5}*\frac{5}{11}\\=-\frac{33}{11}\\=-3[/tex] degrees per hour.

Answer:

The temperature change per hour was -3 degrees per hour.

Step-by-step explanation:

We know that the temperature fell from [tex]0[/tex] degrees to [tex]-6\frac{3}{5}[/tex] degrees in a time period of [tex]2\frac{1}{5}[/tex] hours.

So to find the rate of change of the temperature, we will divide the change in temperature by the number of hours.

For that, we will change the mixed number into improper fractions and then solve:

[tex]-6\frac{3}{5}=-\frac{33}{5}degrees[/tex]

[tex]2\frac{1}{5}=\frac{11}{5} hours[/tex]

Temperature change per hour = [tex]\frac{-\frac{33}{5}}{\frac{11}{5}} = \frac{33}{5}*-\frac{5}{11}=-3[/tex]

Therefore, the temperature change per hour was -3 degrees per hour.

Answer:

5/16

Step-by-step explanation:

We need to change the mixed number to an improper fraction to find the reciprocal

3 1/5 = (5*3+1)/5 = 16/5

The reciprocal of 16/5 is found by flipping the fraction

5/16

Answer:

5/16

Step-by-step explanation:

To find the reciprocal you have to make the fraction a mixed number by multiplying the denominator by the whole number then adding the numerator, in this case it would give you 16/5. Since the reciprocal is the number that you multiply to get one, if you switch the denominator and the numerator, you get 5/16.

You can check your work by multiplying the numbers together, if it equals one, your reciprocal is correct, if not, then you may have to do it again.

Answer: 7 and 8

Step-by-step explanation:

Let x represent the first number, then x + 1 is the other number.

(x)² + (x + 1)² = 113

x²  +  x² + 2x + 1 = 113    expanded (x + 1)²

2x² + 2x + 1 = 113          added like terms

2x² + 2x - 112 = 0        subtracted 113 from both sides

x² + x - 56 = 0           divided both sides by 2

[tex]\frac{4}{5}[/tex] is the ratio form a proportion with [tex]\frac{16}{20}[/tex]

Step-by-step explanation:

Proportion states that the two fraction or ratios are equal.

i.e, [tex]\frac{a}{b} = \frac{c}{d}[/tex]

Given the ratio [tex]\frac{16}{20}[/tex]

To find the proportion of this ratio forms.

[tex]\frac{16}{20}[/tex]

Divide top and bottom by 4 , we have;

[tex]\frac{\frac{16}{4} }{\frac{20}{4} }[/tex]

Simplify:

[tex]\frac{4}{5}[/tex]

therefore, a ratio form a proportion with [tex]\frac{16}{20}[/tex] is, [tex]\frac{4}{5}[/tex]

Option D, 4/5 forms a proportion with 16:20.

To determine which ratio forms a proportion with 16:20, we must find a ratio equivalent to 16:20.

We start by simplifying 16:20. Both 16 and 20 can be divided by their greatest common divisor, which is 4:

16 ÷ 4 = 4

20 ÷ 4 = 5

This gives us the simplified ratio of 4:5. Now, we need to check which of the given options matches 4:5.

4/10: When simplified, 4:10 becomes 2:5, which is not equal to 4:5.

32/50: When simplified, 32:50 becomes 16:25, which is not equal to 4:5.

8/12: When simplified, 8:12 becomes 2:3, which is not equal to 4:5.

4/5: This ratio is already simplified and equal to 4:5.

Therefore, the ratio 4:5 forms a proportion with 16:20.

The population increase in the town is linear, and with a constant increase of 611 people per year, the population is projected to be 4855 in five years.

The population of a town described is increasing at a constant rate, therefore, this represents linear growth. Each year, the population increases by a fixed number, in this case, 611. This contrasts to exponential growth, where the population would increase by a fixed percentage.

To calculate the population in five years, we multiply the rate of increase (611) by the number of years (5) and add the starting population. So, 611*5 = 3055. Adding the current population of 1800 gives us 4855.

Therefore, the population of the town in five years will be 4855, given the linear growth rate holds steady.

Step-by-step explanation:

Let 'm' represents the number of Mylar balloons  and 'l' represents the number of latex balloons.

Given : Mylar balloons cost $1.25 each l, and latex balloons cost $0.75 each.

i.e. cost of m Mylar balloons in dollars = 1.25 m

i.e. cost of l Latex balloons in dollars = 0.75 l

Then, the equations can be used to find the number of each type of balloon in a bunch of 18 balloons that costs $19 will be :-

[tex]m+l=18\\\\1.25 m+0.75 l=19[/tex]

Hence, the correct answer is Option D.[tex]m+l=18\\\\1.25 m+0.75 l=19[/tex]

The equations which can be used from the options given are :

(m + l) = 18

($1.25l + $0.75m) = $19

Cost per mylar balloon, m = $1.25

Cost per latex balloon, l = $0.75

Number of balloons in bunch = 18

Cost of bunch = $19

The cost can be expressed as :

(unit cost of each Ballon × number of each Ballon in a bunch) = total cost of bunch

($1.25l + $0.75m) = $19

Since the total Number of balloons in bunch = 18

And only mylar and latex balloons are present in the bunch ;

Then ;

(Number of mylar+number of latex) balloons = 18

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

[tex]\frac{13}{100} =\frac{2600}{x}[/tex]

We begin solving by cross multiplying numerator to denominator of each fraction.

[tex]13(x)=100(2600)\\13x=260000\\\frac{13x}{13}=\frac{260000}{13}  \\20,000=x[/tex]

Answer:

the company's total budget is 20,000

Step-by-step explanation:

A company spends 13% of its month budget on rent which total $2600

Let x be the month budget on rent

13% of the month budget is 2600

13% can be written as 13/100

[tex]\frac{13}{100} \cdot x=2600[/tex]

Now we solve for x

multiply both sides by 100

[tex]13x= 260000[/tex]

divide both sides by 13

x=20000

So, the company's total budget is 20,000
