It would be this because the 5 would distribute itself multiplying into the 1 and other 5 equaling 5 + 25 and it is in the distributive property.

Answer:

The maximum number of people that can be invited is 65.

Step-by-step explanation:

Based on the information given in the question, the equation to solve the question will be:

80 + 37x = 2500

80+37x=2500

Step 1: Simplify both sides of the equation.

37x+80=2500

Step 2: Subtract 80 from both sides.

37x+80−80=2500−80

37x=2420

Step 3: Divide both sides by 37.

37x/37 = 2420/37

x= 2420/37

x = 65.4

x ≈ 65

Answer:

25 q + 10 d + 5 n + 60 = 187

Step-by-step explanation:

$1.87 = 1.87 x 100 = 187 cents or 187 pennies

Each quarter is worth 25 pennies so q quarters = 25q pennies

Each dime is worth 10  pennies so d dimes = 10d pennies

Each nickel is worth 5 pennies so n nickels = 5n pennies

so 25q + 10d + 5n + 60 = 187

Based on the graph of the function shown, we can logically deduce the following:

The vertical extent of a graph represents all range values and they are always read and written from smaller to larger numerical values, and from the bottom of the graph to the top.

Similarly, the horizontal extent of a graph represents all domain values and they are also read and written from smaller to larger numerical values, and from the left of the graph to the right.

By critically observing the graph of the discrete function shown, we can infer and logically deduce the following:

In conclusion, the function which this graph represents is a discrete function because both the domain and range have discrete set of values, rather than intervals.

3,000 divided by the 500 is 6. It would take 6 days.

When you come across problems like this usually the best way to answer them is d (distance) divided by s (speed, miles per day, miles per hour, miles per second, etc.).

Answer:

42/5% as a decimal is 8.4

By using basic arithematic operations we concluded that the temperature at 6 pm was - 9.8°F.

Arithmetic operation is the study of numbers and the operations on numbers that are used in all other branches of mathematics. It primarily consists of basic operations like addition, subtraction, multiplication, and division.

The temperature at 09:00 am = -6.9°F.

The tempertaure increased by 5.4°F till noon

So, the final tempertaure at noon = - 6.9°F + 5.4°F

                                                        = - 1.5°F

Then, again the temperature increased by 7.2°F from noon till 3 pm.

So, the final tempertaure at 3 pm = - 1.5°F + 7.2°F

                                                        =  5.7°F

Then, again the temperature by dropped 15.5°F from 3 pm to 6 pm.

So, the final tempertaure at 6 pm = 5.7°F - 15.5°F

                                                        = - 9.8°F

Therefore the temperature at 6 pm was - 9.8°F.

In San Francisco, the tax on a property with a $860,000 assessed value is $12900.

In Tacoma, the tax on a property assessed at $330,000 is $4,950.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $860,000.

So, we need to determine the tax rate of Tacoma first.

Tax Rate = Tax / Property assessed × 100.

[tex]Tax {~}rate = \frac{4950}{330000} \times 100[/tex]

Tax rate = 0.015 × 100

Tax rate = 1.5%

From the question, the tax rates are proportional.

Now, we apply the same tax rate as Tacoma in this city:

Tax = tax rate of property assessed.

Tax = 1.5% of $860,000

[tex]Tax=\frac{1.5}{100} \times 860000[/tex]

Tax = 1.5 × 8600

Tax = $12900

Therefore, the tax on property in San Francisco assessed at $860,000 is $12900.

The cost for each pound of walnuts is $ 2.25 and each pound of chocolate chips is $ 1.5.

We are given that:

Cost of 4 pounds of walnuts and 8 pounds of chocolate chips = $ 21.

Cost of 2 pounds of walnuts and 3 pounds of chocolate chips = $ 9.

Let the cost of pounds of walnuts be x and the cost of pounds of chocolate chips be y.

So, we get the following equations:

4 x + 8 y = 21    …(1)

2 x + 3 y = 9

2 x = 9 - 3 y

x = 1 / 2 (9 - 3y)   …(2)

Put the value of x in (1)

4 ( 1 / 2 (9 - 3y) ) + 8 y = 21

2(9 - 3y) + 8 y = 21

18 - 6 y + 8 y = 21

2 y + 18 = 21

2 y = 21 - 18

2 y = 3

y = 3 / 2

y = 1.5

x = 1 / 2 (9 - 3y)

x = 1 / 2 ( 9 - 4.5)

x = 1 / 2 ( 4.5)

x = 2.25

Therefore, we get that, the cost for each pound of walnuts is $ 2.25 and each pound of chocolate chips is $ 1.5.

Answer: The answer is in the picture!

Step-by-step explanation:

The no. of sales made by the agent if he calls 20 clients is 43.

The basic equation used to represent and solve for an unknown quantity is a linear equation in one variable. It is always a straight line and can be represented graphically. A linear equation is a straightforward way of representing a mathematical statement. Unknown quantities can be represented by any variable or symbol, but in most cases, in a linear equation with one variable, a variable 'x' is used to represent the unknown quantity.

No. of sales =18.9476+1.1842x

Here x = no. of phone calls

The agent calls 20 client.

So, x = 20

Put x = 20 in the given no. of sales. equation

No. of sales = 18.9476 + (1.1842)(20)

No. of sales = 18.9476+23.684

No. of sales = 42.6316

Since the number of sales can't be in decimal numbers, so we will round off the given no. of sales.

Therefore, the no. of sales = 43
