Perimeter: 36

5n + 3 = 36
5 · 6.6 + 3 = 36

N = 6.6
------------------------------------------
Perimeter: 36

1/4n + 2 = 36
1/4 · 136 + 2 = 36

N = 136

Hopefully i understood the question correctly :) Hope this helps

X=20. By using the bottom sides of each figure, you can calculate that the figure on the right is 3 times larger than the similar figure on the left. This means that 2x+5=45. When solved, this yields x=20.

Answer:

1. N=120

2. n=2

3. N=66

4. n=5

5. N=21

6. n=20

7. n=1398

8. n=5

Step-by-step explanation:

1.

N-80=40

N=40+80

N=120

2.

15n=30

\dfrac{15n}{15}=\dfrac{30}{15}

n=2

3.

N+284=350

N=350-284

N=66

4.

6+9=3\times n

15=3n

\dfrac{15}{3}=n

n=5

5.

\dfrac{N}{3}=6+1

\dfrac{N}{3}=7

N=7\times 3

N=21

6.

12-8=\dfrac{n}{5}

4=\dfrac{n}{5}

4\times 5=n

n=20

7.

58\times 6=n-(723 + 327)

348=n-1050

348+1050=n

1398=n

8.

4n+12=(7+9)\times 2

4n+12=16\times 2

4n+12=32

4n=32-12

4n=20

n=\dfrac{20}{4}

n=5

Therefore, the solutions are 1. N=120

2. n=2

3. N=66

4. n=5

5. N=21

6. n=20

7. n=1398

8. n=5
