Marco had 21 party favors. He put them into 7 bags with the same
number in each bag. How many party favors were in each bag?

Answer:

B

Step-by-step explanation:

Answer:

[tex]\dfrac{x^3-2x^2+4x-3}{x-2}[/tex]

Step-by-step explanation:

The given equation is :

[tex]x^2+\dfrac{4x-3}{x-2}[/tex]

We need to decompose this equation.

We have,

[tex]x^2+\dfrac{4x-3}{x-2}\\\\=\dfrac{x^2(x-2)+4x-3}{x-2}\\\\=\dfrac{x^3-2x^2+4x-3}{x-2}[/tex]

So, [tex]\dfrac{x^3-2x^2+4x-3}{x-2}[/tex] is the decomposed form of the given expression.

Answer:

If the price increase happens, your order would be $50.4.

Step-by-step explanation:

To be able to determine how much would the order be if the price increase happens, first you have to calculate 12% of the normal price per order:

$45*12%=$5.4

Then, you have to add $5.4 that is the amount of the increase plus the normal price per order:

$5.4+$45=$50.4

According to this, the answer is that if the price increase happens, your order would be $50.4.

Answer:

15x+9y= 360----------1

x+y= 30--------------2

Step-by-step explanation:

Step one:

given data

let adult be x

and child be y

A hairstylist charges $15 for an adult haircut and $9 for a child haircut

She wants to earn $360 dollars

15x+9y= 360----------1

and cut 30 haircuts this week

x+y= 30--------------2

Step two:

Hence the system of equations for the situation is given as

15x+9y= 360----------1

x+y= 30--------------2

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1). Unit rate = slope of the graph at x =1

   Unit rate means value of y at x = 1

   From the graph of the given function,

   (1, 2) is the point which defines the unit rate.

2). Table (1),

   If the data shows the proportional relationship,

   [tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]

   [tex]\frac{2}{6}=\frac{1}{3}[/tex]

   [tex]\frac{1}{3}= \frac{1}{3}[/tex]

   Therefore, table (1) represents the proportional relationship.

   Table (2),

   If the data given in table is proportional,

   [tex]\frac{y_1}{x_1}=\frac{y_2}{x_2}[/tex]

   [tex]\frac{8}{5}=\frac{4}{2}[/tex]

   [tex]\frac{8}{5}=\frac{2}{1}[/tex]

   Which is not true.

   Therefore, table (2) doesn't show the proportional relationship.

Answer:

$6.98

Step-by-step explanation:

0.29x+1.23y=Total amount

x=pounds of potatoes

y=pounds of onions

Substitute:

0.29(3.7)+1.23(4.8)

Multiply:

1.073+5.904

Add:

6.977

Round:

6.98

Step-by-step explanation:

So we just need to complete the table

So we need the next three x digits which is

[tex]\frac{8}{5}, \frac{12}{5}, \frac{16}{5}[/tex]

Next y digits would be

[tex]\frac{2}{2}, \frac{3}{2}, \frac{4}{2}[/tex]

Hope This Helped!!

(Just fill out the x rows with the next x digits and the y rows with the next y digits)

Step-by-step explanation:

Subtracts those with same units but given that 40" is lower than 50", we need to borrow from 50' which can be read as 50 minutes.

40" is read as 40 seconds. Since 1 minute has 60 seconds, we have:

40" + 60" = 100" and

50' - 1' = 49'

These values will yield 60° 49' 100"

Now that the upper values are higher than the one below, we can now perform the operation:

60° - 30° = 30°

49' - 40' = 9'

100" - 50" = 50"

Answer:

(-3)^4

Step-by-step explanation: We just have to evaluate

So, the only expression that exceeds 4^3 is (-3)^4:

12x - 7 = 77

Answer: 6,987,000 pounds fo CO₂ per kWh.

Step-by-step explanation: Quilowatt-hour (kWh) is a unit of energy that measures the amount of energy expended in 1 hour.

The AC uses 850 Watts, which in kW is 850,000 kW

If you leave the AC on for 6 hours, it will consume

850,000(6) = 5,100,000 kWh

Eletricity produces 1.37 pounds of CO₂ per kWh, then in 5,100,000 kWh:

1.37 [tex]\frac{pounds}{kWh}[/tex].(5,100,000kWh) = 6,987,000 pounds

If you open a window for 6 hours, you would keep 6,987,000 pounds of CO₂ for entering the atmosphere.

Answer:

Answer is explained below in the explanation section.

Step-by-step explanation:

Note: This question is very generic and incomplete. So, I will be using the general properties of operation for a general expressions for the sack of understanding and concept.

Solution:

There are several properties of arithmetic operations. But here, we will be discussing about the common properties of operations.

1. Commutative property of Addition

2. Commutative property of Multiplication

3. Associative property of Addition

4. Associative property of Multiplication

Let's Start,

1. Commutative property of Addition:

a + b = b + a

it means that if we add 2 to 3 or 3 to 2, the result will be same.

2 + 3 = 3 + 2

5 = 5

Similarly.

2. Commutative property of Multiplication:

a x b = b x a

it means that if we multiply 2 to 3 or 3 to 2, the result will be same.

2 x 3  = 3 x 2

6 = 6

3. Associative property of Addition:

Let's suppose we have 3 variables now,

a, b and c

so,

a + (b + c)  = (a + b) + c

2 + (3 + 5)  = (2 + 3) + 5

2 + (8) = (5) + 5

10 = 10

Similarly.

4. Associative property of Multiplication:

a x (b x c)  = (a x b) x c

2 x (3 x 5)  = (2 x 3) x 5

2 x ( 15) = (6) x 5

30 = 30

Hence, these operations are very useful in solving the bigger and complex questions in mathematics.
