Answer 1

Answer:

12) s=$\frac{p}{5}$

13) A=wh

14) p=a+b+c

15) A=$\frac{bh}{2}$

16) p-b-c=a

Step-by-step explanation:

12) $\frac{p}{5} =\frac{5s}{5}$

13) $\frac{A}{h}$=W (multiply both sides by h)

14) take c to the other side of the equation( other side of the equal sign) it becomes a positive value

15) Divide both sides by 2

16) take b + c to the other side of the equation where it becomes -b-c

Answer 2

Answer:

12. $\frac{P}{5}$ = s

13. A = wh

14. P = a + b + c

15. A = $\frac{bh}{2}$

16. P - c - b = a

Step-by-step explanation:

12. P = 5s

Divide both sides by 5:

P/5 = 5s/5

$\frac{P}{5}$ = s

13. $\frac{A}{h}$ = w

Multiply both sides by h:

$\frac{A}{h}$ (h)= w(h)

A = wh

14. P - c = a + b

Add c to both sides:

P - c + c = a + b + c

P = a + b + c

15. 2A = bh

Divide both sides by 2:

2A/2 = bh/2

A = $\frac{bh}{2}$

16. P = a + b + c

Subtract c from both sides of the equation:

P - c = a + b + c - c

P - c = a + b

Subtract b from both sides:

P - c - b = a + b - b

P - c - b = a

Hope this helps :)
