Respuesta :

The given information can be written as an equation from which the

solution can be found.

  • [tex]Question \ 1: \displaystyle \underline{\frac{14 - 6}{6 - 2} \ <\ 4 \times (10 - 8)- 2 \times 2}[/tex]
  • Question 2: The equation is 0.4 × n = 8; n = 20
  • Question 3: The equation is C + $3.49 = $9.84; The solution is the original cost, C = $6.35

Reasons:

Question 1: The possible expression is presented as follows;

[tex]\displaystyle \frac{14 - 6}{6 - 2} \ and \ 4 \times (10 - 8)- 2 \times 2[/tex]

The comparison values are;

<, >, or =

Solution:

[tex]\displaystyle \frac{14 - 6}{6 - 2} = \frac{8}{4} = 2[/tex]

4 × (10 - 8) - 2 × 2 = 4

2 < 4

Therefore;

[tex]\displaystyle \underline{\frac{14 - 6}{6 - 2} \ <\ 4 \times (10 - 8)- 2 \times 2}[/tex]

Question 2: The given statement can be presented as the following equation:

0.4 × n = 8

The solution of the above equation is therefore;

[tex]\displaystyle n = \frac{8}{0.4} = 20[/tex]

n = 20

Question 3: The amount by which the cost of the toy is increased = $3.49

New price of the toy = $9.84

The original cost of the toy = C

The equation is therefore, C + 3.49 = 9.84

C = 9.84 - 3.49 = 6.35

The original cost of the toy, C = $6.35
