Answer:

x = 9

Step-by-step explanation:

I think you wrote the question wrong (I am assuming that there is a x next to the -3).

Subtract 7

-27 = -3x

divide by -3

9 = x

Solve the literal equation for x.<br> g=4x+5xy
Tasya [4]

The literal equation for x is g/4+5y

<h3>Subject of formula</h3>

This is a way of representing a variable in terms of another

Given the equation below;

g=4x+5xy

Factor out x to have

g=x(4 + 5y)

Divide both sides by 4 +5y to have:

g/4+5y = x

x = g/4+5y

Hence the literal equation for x is g/4+5y

Use the quadrant system to find the area of the polygon.
adoni [48]

Consider the bottom most rectangle.

Its length = 5 - 2 = 3 units

Its width = 3 - 1 = 2 units

So, its area = 3(2) = 6 square units.

Consider the middle rectangle.

Its length = 2 - 1 = 1 unit

Its width = 4 - 2 = 2 units

So, its area = 1(2) = 2 square units.

Finally, consider the top rectangle.

Its length = 6 - 1 = 5 units

Its width = 6 - 4 = 2 units

Its area = 5(2) = 10 square units.

Hence, total area = 6 + 2 + 10 = 18 square units. Correct option is C.
