Answer:

5 pizzas and 17 sodas were bought

Step-by-step explanation:

Here, we want to get the number of pizza and sodas bought

Let n be the number of pizzas bought

we are told that the number of sodas bought was 2 more than 3 times the number of pizzas

So the number of sodas will be;

3n + 2

So let’s have the equations based on the prices;

pizzas cost $9.50, soda cost $1.25

Thus;

9.5n + 1.25(3n + 2) = 68.75

9.5n + 3.75n + 2.5 = 68.75

13.25n = 68.75 - 2.5

13.25n = 66.25

n = 66.25/13.25

n = 5

Number of pizzas bought is 5

number of soda is 3n + 2 = 3(5) + 2 = 15 + 2 = 17

The height of 100 Canadian dimes is 1220 millimeter.

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have 1000 Canadian dimes.

Assume that the height of 100 Canadian dimes is [x] mm. Then, we can write -

[x] = 1000 x 1.22

[x] = 1220 mm

Therefore, the height of 100 Canadian dimes is 1220 millimeter.

Answer:

Step-by-step explanation:

Step one:

given data

the initial amount of chemical = 1.25 ounces

Extra amount of chemical =2.5 ounces

Total amount of chemical =1.25+2.5=3.75 ounces

Step two:

we are told that the scientist used 0.75 ounces of chemical

Hence the remaining chemical is

remaining= 3.75-0.75

remaining= 3 ounces

The remainder is 3 ounces

Answer:

x=12.8

Step-by-step explanation:

34x+85=39x+21

34x-39x=21-85

-5x = -64

x = -64/-5

x = 12.8

Answer:

x = 34/5

Step-by-step explanation:

Just solve the equation

[tex]34x + 85 = 3(13x + 17)\\34x + 85 = 39x + 51\\85 - 51 = 39x - 34x\\34 = 5x\\x = 34/5[/tex]

Answer:

the number of businesses with no employees is 7,050,000

Step-by-step explanation:

The computation of the number of businesses in the economy have no employees is shown below:

Given that

There are a total of 28,200,000

Out of which 25% of those businesses have no employees

So, the number of businesses in the economy is

= 28,200,000 × 25%

= 7,050,000

Hence, the number of businesses with no employees is 7,050,000

Answer: The greatest number of pages Kenji can decorate = 3

Step-by-step explanation:

Given: Total heart stickers = 15

Total star stickers =12

If all the papers identical, with the same combination of heart and star stickers and no stickers left over.

Then the greatest number of pages Kenji can decorate = GCD(15,12)  [GCD=greatest common divisor]

Since 15 = 3 x 5

12=2 x 2 x 3

GCD(15,12) =3

Hence, the greatest number of pages Kenji can decorate = 3

Answer:

Future cost per gallon= $15.05

Step-by-step explanation:

Giving the following information:

Oil prices are projected to increase by 75% by next May. A quart of oil currently costs $2.15.

We know that 1 quart equals 0.25 gallons.

First, we will determine the actual cost per gallon.

Actual cost per gallon= 2.15*4= $8.6

Now, the cost for May:

Future cost per gallon= 8.6*1.75

Future cost per gallon= $15.05

Answer:

Decimal Form:

8.3

Mixed Number Form:

81 /3

B.) The horizontal asymptote y = 11.95 represents that the cost per person approaches $11.95 as the number of people increases.

Good luck with the test! :)

The horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.

"An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity."

"The curves visit these asymptotes but never overtake them. The method opted to find the horizontal asymptote changes involves comparing the degrees of the polynomials in the numerator and denominator of the function. If both the polynomials have the same degree, divide the coefficients of the largest degree terms."

From the equation, y = 11.95x + 25

And from the given graph it is clear that the horizontal asymptote y = 0 represents that the cost per person approaches $0 as the number of people increases.

Hence, A is the correct option.
