What value of x makes 1/2 (3x+4) =1/2

Sever21 [200]

Answer:

x = -1

Step-by-step explanation:

1/2 (3x +4 ) = 1/2

1/2 x 3x + 1/2 x 4 = 1/2

1.5 x + 2 = 1/2

1.5x = 1/2 -2

1.5x = -1.5

1.5x /1.5 = -1.5/1.5

x = -1

allochka39001 [22]

Answer:

5.73cm

Step-by-step explanation:

Given parameters:

Circumference of the circle = 36cm

Unknown

Length of the radius = ?

Lets represent the radius by r

Solution

The circumference of a circle is the defined as the perimeter of a circle. The formula is given as:

Circumference of a circle = 2πr

Since the unknown is r, we make it the subject of the formula:

r = $\frac{circumference of the circle}{2π}$

r = $\frac{36}{2 x 3.142}$ = $\frac{36}{6.284}$ = 5.73cm
