-15x - 3y = 3
-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x =

[divide by -30 to get x alone]
x =

[reduce the fraction]
Hopefully this is helpful enough to get you to your answer
The correct option is B. Distributive property
Given,
On solving the above equation,
multiplying both sides by 3 we, get

now subtracting 21 from both the sides,

dividing both the sides by 2 we get,

Since in the above steps we follow all the giving property except the distributive property.
Hence the correct option is B. Distributive property.

Answer:

Explanation:
<u>Given Expression</u>:
Use the Quadratic Formula:

<u>insert coefficients</u>





The centroid of a triangle divides the median of the triangle into 1 : 2
The measure of FQ is 18, while the measure of TQ is 6
Because point T is the centroid, then we have the following ratio

Where FT = 12.
Substitute 12 for FT in the above ratio

Express as fraction

Multiply both sides by 12

This gives

Divide 12 by 2

The measure of FQ is calculated using:

Substitute 12 for FT, and 6 for TQ

Add 12 and 6

Hence, the measure of FQ is 18, while the measure of TQ is 6
