Hey there.

12 + 2n = 20
Subtract 12 from both sides of the equation. This isolates our variable.
2n = 8
Divide both sides by 2, the number that's being multiplied by our variable. This isolates and solves for our variable.
n = 4; Your answer is D.)

I hope this helps!

3x-5=-6x+13 : Given

3x=-6x+18 : Addition property of Equality

9x=18: Subtraction property of Equality

x=2: Division Property of Equality

Step-by-step explanation:

We need to give justification to each step

Step 1:

3x-5=-6x+13

This is the question given, which we need to solve and find value of x.

Justification: Given

Step 2:

Adding 5 on both sides of the equation using addition property of equality.

3x-5+5=-6x+13+5

Simplifying

3x=-6x+18

Justification: Addition property of Equality

Step 3:

Adding 6x on both sides of the equation

3x+6x=-6x+18+6x

9x=18

Justification: Subtraction property of Equality

Step 4:

Divide both sides of the equation by 9, to find the value of x using division property of equality

9x/9=18/9

x=2

Justification: Division Property of Equality

Find the area, correct to the nearest square

Lady bird [3.3K]

Answer:

1269 square meters

Step-by-step explanation:

The path and the plot of land form two concentric circles (they have the same center). The radius of the plot of land is 100m (half of the diameter) and the radius of the larger circle, formed by putting a 2m wide path around the plot of land, is 102m. Thus, the area of the path is $\pi *102^2$ minus $\pi *100^2$ which will be $10404\pi-10000\pi$ which is $404\pi$ . Estimate $\pi$ to 3.141 and calculate, getting 1268.964... which is 1269, rounded to the nearest square meter.

Hope this helps :)
