Step-by-step explanation:

The answer is x-3. We don't know the brother's height, so we make it into a variable. You may pick any variable, but x is a common choice. We then subtract 3 from x, which would give us Aria's height. Since we don't know the height of the brother, we won't know Aria's height.

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:

The value of x = 8.5

The value of FG = 8.5 units

Step-by-step explanation:

Given

Determining the value of x

As F is between E and G, so

EF = FG

7 = 2(x-5)

7 = 2x-10

2x = 7+10

2x = 17

divide both sides by 2

2x/2 = 17/2

x = 8.5

Thus,

The value of x = 8.5

Determining the value of FG

As

FG = 2(x-5)

substituting x = 8.5

FG = 2(8.5 - 5)

FG = 2(3.5)

FG = 7

Thus,

The value of FG = 8.5 units

Summary:

The value of x = 8.5

The value of FG = 8.5 units

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:

35 more video games

Step-by-step explanation:

40 times 3 and then substract 85

120-85=35

Answer:

89

Step-by-step explanation:

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"

Checking with a calculator:

Answer:

    [tex]\frac{(x+3)^{2} }{(x+3)(x^{2} +1)}[/tex]      =   [tex]\frac{x }{(x^{2} +1)} +\frac{3 }{(x^{2} +1)}[/tex]

Step-by-step explanation:

Step(i):-

Given  expression

        [tex]\frac{(x+3)^{2} }{(x+3)(x^{2} +1)}[/tex]

      = [tex]\frac{(x+3) }{(x^{2} +1)}[/tex]

Step(ii):-

    = [tex]\frac{x }{(x^{2} +1)} +\frac{3 }{(x^{2} +1)}[/tex]

Angle A (6x +11)  = 53

12x - 7 = 77

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.
