Answer:

a=2/3

Step-by-step explanation:

All this problem needs is some knowledge of how an = sign and basic equations work

7a-3=3-2a

7a+2a=3+3 (Sign becomes opposite on the other side of the equation)

9a=6

a=2/3

Thank you for your time!

Answer:

27.

Step-by-step explanation:

x/3 −9=0 Step 1: Simplify both sides of the equation. x/3 −9=0 1/3 x+−9=0 1/3 x−9=0 Step 2: Add 9 to both sides. 1/3 x−9+9=0+9 1/3 x=9 Step 3: Multiply both sides by 3. 3*( 1/3 x)=(3)*(9) x=27

If the circumference is 3/2 pi what is the area

11111nata11111 [884]

Here is your answer

$\frac{9}{16} \pi \: {units}^{2}$

REASON:

Circumference(C)= 2πr

, where r is radius

Given

C= (3/2) π

So,

$2\pi \: r = \frac{3}{2}\pi$

$r = \frac{\frac{3}{2}\pi}{2\pi}$

$r = \frac{3}{4}$

Now,

$area = \pi {r}^{2}$

$= \pi \times { (\frac{3}{4}) }^{2}$

$= \frac{9}{16}\pi \: {unit}^{2}$
