Answer:

1.62 pounds

Step-by-step explanation:

Let x be the pounds of Arabica

Take the number of pounds times the cost of each of the coffees individually

This must be equal to the number of pounds times the cost together

x * 28 + 8.75 *3 = ( x+3) 15.50

28x+26.25=(x+3)15.50

Distribute

28x+ 26.25 = 15.50x + 46.50

Subtract 15.50x from each side

28x-15.50x +26.25 = 15.50x +46.50-15.50x

12.50x + 26.25 = 46.50

Subtract 26.25 from each side

12.50x +26.25-26.25 = 46.50-26.25

12.50x = 20.25

Divide each side by 12.5

12.5x/12.5 = 20.25/12.5

x =1.62

Answer:

3 1/9

Step-by-step explanation:

28/9=

9*3=27 r1

3 1/9

Answer: 3 1/9  

Step-by-step explanation:

Step 1 - Find Whole Number

Calculate out how many times the denominator goes into the numerator. To do that, divide 28 by 9 and keep only what is to the left of the decimal point:  28 / 9 = 3.1111 = 3

Step 2 - Find New Numerator

Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.  28 - (9 x 3) = 1

Step 3 - Get Solution

Keep the original denominator and use the answers from Step 1 and Step 2 to get the answer.

The required divide of 7.2 divided by 42.12 is 0.170940171 which is none terminating recurring decimal.

Given that,
To evaluate the solution of the numeral 7.2 divided by 42.12.

A recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.

Here,
According to the question,
7.2 / 42.12 = 0.170940171
Which is a recurring decimal.

Thus, the required divide of 7.2 divided by 42.12 is 0.170940171 which is none terminating recurring decimal.

Answer:

63

Step-by-step explanation:

Jason age will be 63 years.

What is an expression?

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

The condition is given as;

'' Jason says that 10 less than one third of his age is 11 years old. ''

Now,

Let age of Jason = x years

Then, By the given condition we formulate;

1/3 x - 10 = 11

Solve for x as;

1/3 x - 10 = 11

Add 10 both side;

1/3 x - 10 + 10 = 11 + 10

1/3 x = 21

Multiply by 3;

x = 63

Thus, Jason age will be 63 years.

Answer:

m∠CEH = 79°

Step-by-step explanation:

From the picture attached,

∠CED and ∠CEH are the pair of linear angles.

Since, pair of linear angles are supplementary angles.

m∠CED + m∠CEH = 180°

101° + m∠CEH = 180°

m∠CEH = 180° - 101°

             = 79°

Therefore, measure of angle CEH is 79°.

t = 3

Step-by-step explanation:

5t - 4 = 11

5t - 4 + 4 = 11 + 4 (you do the plus 4 to get rid of the -4 and what you do to one side you have to do to the other.)

5t = 15

5t/5 = 15/5 (To get red of the 5 do reverse operation.)

1t = 3 simplified to

t = 3

Answer:

Price of Adult tickets =$ 13

Price of student tickets =$ 8

Step-by-step explanation:

Lets us represent the price of adult tickets = x

The price of student tickets = y

On the first day of ticket sales the school sold 10 adult tickets and 13 student tickets for a total of $234.

= 10 × x + 13 × y = $234

= 10x + 13 y = 234

The school took in $97 on the second day by selling 5 adult tickets and 4 student tickets.

5 × x + 4 × y = $97

= 5x + 4y = 97

Hence:

10x + 13y = 234......Equation 1

5x + 4y = 97......... Equation 2

We solve by elimination method

Multiply the equation 1 by 5 and equation 2 by 10 which are the coefficient of x

10x + 13y = 234......Equation 1 × 5

5x + 4y = 97......... Equation 2 × 10

50x + 65y = 1170......Equation 3

50x + 40y = 970..... Equation 4

Subtract Equation 4 from Equation 3

25y = 200

y = 200/25

y = 8

Therefore the price of student ticket = $8

Note that

5x + 4y = 97......... Equation 2

5x + 4 × 8 = 97

5x = 97 + 32

5x = 65

x = 65/5

x = 13

Therefore price of adult tickets = $13

Answer: 7 5/7 (the bottom one)

Step-by-step explanation:

30 divided by 2 = 15 (do the same to 42 and get 21)

This then creates the fraction: 15/21

Now, divide this fraction by 3 and get 5/7

Add back in the seven because you aren't dividing the whole number.

Your final answer is now 7 and 5/7 (together: 7 5/7)

Answer: 7

Step-by-step explanation:

Step-by-step explanation:

the answer you picked looks like an image on my notes

sorry if its not

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = [tex]\frac{1}{2}[/tex] and (a, b) = (3, - 2) , thus

y - (- 2) = [tex]\frac{1}{2}[/tex] (x - 3) , that is

y + 2 = [tex]\frac{1}{2}[/tex]( x - 3) ← in point- slope form

(b)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = [tex]\frac{1}{2}[/tex] , thus

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = [tex]\frac{3}{2}[/tex] + c ⇒ c = - 2 - [tex]\frac{3}{2}[/tex] = - [tex]\frac{7}{2}[/tex]

y = [tex]\frac{1}{2}[/tex] x - [tex]\frac{7}{2}[/tex] ← in slope- intercept form
