Answer:

16

Step-by-step explanation:

x + 6 = 4x

6 = 3x

x = 2

2 + 6 + 4(2) = 16

Answer:

10x + 24

Step-by-step explanation:

distribute first to remove parentheses:

4x + 12 + 6x + 12

now combine 'like terms':

10x + 24

Answer:

10x + 24

Step-by-step explanation:

Expand the brackets by multiplying each term in the bracket by the expression outside the bracket:

4(x + 3) + 6(x + 2) = 4x + 12 + 6x + 12

Gather like terms:

4x + 6x + 12 + 12

Combine like terms:

10x + 24

You should plot an arrow, with open-circle, starting in the number 9. See the image attached.

It is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use of follow symbols: [tex]\leq[/tex] (less than or equal to), [tex]\geq[/tex] (greater than or equal to), < (less than) and > (greater than).

The solutions for inequalities can be given by: graph in a number line or numbers. Your question requests a graph solution, but it is necessary to find a number solution to plot it in the graph.

Answer:

-5(8) = -40-5(-2x) = -40+10x

The value of an equivalent expression is,

⇒ 10x - 40

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

Given that;

Expression is,

⇒ - 5 (8 - 2x)

Now, We can simplify as;

⇒ - 5 (8 - 2x)

⇒ - 5 × 8 - 5 × - 2x

⇒ - 40 + 10x

⇒ 10x - 40

Thus, The value of an equivalent expression is,

⇒ 10x - 40

Step-by-step explanation:

You have to multiply 28× 1 3/8

You can convert yhe 1 3/8 to an improper fraction, then multiply, and convert back to a mixed number. See image.

OR,

you can distribute the 28 over the sum of 1 and 3/8. This just keeps the fraction a little bit smaller and you can practice distributive property see image

Answer:

Alvin's Age is 81 and Elga's age is 27

Step-by-step explanation:

let A be Alvin's age and E be Elga's age

A = 3 E (alvin's age is three times elga's age)

A + E = 108 ( the sum of their ages is 108)

3E + E = 108

4 E = 108

E= 108/4 = 27

A = 3E = 27*3 = 81

⭐ Let the Alvin's age be "a" and the Elga's age be "e".

⭐ If we carefully identify the question, we can get two hints provided in the question which can be framed into equations. They are,

(Alvin's age is 3 times the age of Elga's age)

(The sum of Alvin's and Elga's age is 108)

Substituting value of A i.e (A = 3E) in eqn (2) so as to get same variable and solve the eqn.

[tex]\Rrightarrow\bf{a + e = 108}[/tex]

[tex]\Rrightarrow\bf{3e + e = 108}[/tex]

[tex]\Rrightarrow\bf{4e = 108}[/tex]

[tex]\Rrightarrow\bf{e = \frac{108}{4} }[/tex]

[tex]\Rrightarrow\bf{e = 27}[/tex]

Substituting value of (e = 27) in eqn (1),

[tex]\Rrightarrow\bf{a = 3e}[/tex]

[tex]\Rrightarrow\bf{a = 3 \times 27}[/tex]

[tex]\Rrightarrow\bf{a = 81}[/tex]

Based on the information given, it should be noted that the cost of the pretzel is $0.04.

Let the coke be represented by c.

Let the pretzel be represented by p.

Based on the information,

c = p + 2 ..... i

c + p = 2.08 ... ii

p + 2 + p = 2.08

2p + 2 = 2.08

2p = 2.08 - 2

2p = 0.08

p = 0.08/2 = 0.04

Therefore, c = 2 + 0.04 = 2.04

Answer:

x = 2[tex]\sqrt{10}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

x² + 9² = 11²

x² + 81 = 121 ( subtract 81 from both sides )

x² = 40 ( take square root of both sides )

x = [tex]\sqrt{40}[/tex] = [tex]\sqrt{4(10)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{10}[/tex] = 2[tex]\sqrt{10}[/tex] ≈ 6.32 ( to 2 dec. places )
