1/6d + 2/3 = 1/4(d-2) how to solve

natita [175]

Greetings!

Solve for d.
$1/6d + 2/3 = 1/4(d-2)$
Distribute the Parenthesis.
$1/6d + 2/3 = 1/4*d+1/4*-2$
$1/6d + 2/3 = 1/4d+1/4*-2/1$
$1/6d + 2/3 = 1/4d-2/4$
Reduce.
$1/6d + 2/3 = 1/4d-1/2$
Add -2/3 to both sides.
$(1/6d + 2/3)+(-2/3)=(1/4d-1/2)+(-2/3)$
Simplify.
$1/6d=1/4d-3/6-4/6$
$1/6d=1/4d-7/6$
Add -1/4d to both sides.
$(1/6d)+(-1/4d)=(1/4d-7/6)+(-1/4d)$
Simplify.
$2/12d)-3/12d=-7/6$
$-1/12d=-7/6$
Divide both sides by -1/12.
$(-1/12d)/-1/12=(-7/6)/-1/12$
Simplify.
$d=(-7/6)*-12/1$
$d=84/6$
Reduce.
$d=14/1$
$d=14$

Hope this helps.

What is the approximate circumference of a circle with a diameter of 14 inches, rounded to the nearest inch? (Use 3.14 as an app

soldi70 [24.7K]

Answer:

44 in.

Step-by-step explanation:

pi = 3.14 (in our case)

circumference = diameter x pi

circ. = 14 x 3.14, which equals to 43.96

round that and you get 44 in.

Circle Phas a circumference of approximately 75 inches.

Dominik [7]

Answer:

12 inches

First choice

Step-by-step explanation:

Solve using the formula for circumference.

C = 2πr

"C" is the circumference, which we know C = 75 in.

π = 3.14 in this problem.

"r" is the radius, which we are finding.

Substitute the numbers you know for the variables of the formula.

C = 2πr

(75in) = 2(3.14)r

Since we are finding "r", we need to isolate it. If we divide the right side by 2(3.14), it cancels out and "r" will be alone.

$\frac{75in}{2*3.14} = \frac{2*3.14*r}{2*3.14}$

$\frac{75in}{2*3.14} = r$

Put the variable on the left side for standard formatting.

$r = \frac{75in}{2*3.14}$ Now simplify the fraction.

$r = \frac{75in}{6.28}$ 2 times 3.14 is 6.28

$r = \frac{75in}{6.28}$ Divide the top by the bottom

r = 11.9426752 in Exact decimal answer

r ≈ 12in Rounded answer to nearest inch
