120% of x is equal to 78
Write an equation that shows the relationship of 120%, x, and 78

or

Step-by-step explanation:

Given:

120% of x is equal to 78

We need to write an equation that shows the relationship of 120%, x, and 78

Solution:

We can write the 120% of x as:

⇒ 120% of x

Substitute in the place of 120%.

⇒

So, we write the equation as:

120 and 100 divided by 10.

Applying cross multiplication rule.

Therefore, equation shows the relationship of 120%, x, and 78.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
