Answer:

1. 24

2. 4.444... (or 4 rounded to the nearest whole number)

Step-by-step explanation:

1. 80/100 = x/30

<u><em>cross-multiply</em></u>

100 × x = 100x

80 × 30 = 2400

<u><em>divide</em></u>

100x/100 = x

2400/100 = 24

<u><em>answer</em></u>

x = 24

2. 90/100 = 4/x

<u><em>cross-multiply</em></u>

90 × x = 90x

100 × 4 = 400

<u><em>divide</em></u>

90x/90 = x

400/90 = 4.444...

<u><em>answer</em></u>

x = 4.444...

Use the linear combination method to solve the system of equations.
Kaylis [27]

For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The solution of the system of equation is (-3.4, -9).

<h3>What is the system of equations?</h3>

Inconsistent System

For a system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System

1. Dependent Consistent System

For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.

2. Independent Consistent System

For a system of the equation to be an Independent Consistent System, the system must have one unique solution for which the lines of the equation must intersect at a particular.

Add the two equations,

–2.1x + 4y + 2.1x – 5.5y = –0.2 + 5.3

-2.1x + 2.1x + 4y -5.5y = 5.1

-1.5 y = 5.1

y = 5.1/1.5

y = -3.4

Now, substitute the value of y in any one of the equation, therefore,

-2.1x + 4y = 5.3

-2.1x + 4(-3.4) = 5.3

-2.1x - 17.36 = 5.3

-2.1x = 22.66

x = -9

Hence, the solution of the system of equation is (-3.4, -9).
