Answer:

C No; -4 -8 is -12 and 3 x -12 is -36.

Step-by-step explanation:

Let's solve your equation step-by-step.

d /3 + 8= −4

Step 1: Simplify both sides of the equation.

1 /3 d + 8 = −4

Step 2: Subtract 8 from both sides.

1 /3 d + 8 − 8 = −4 − 8

1 /3 d = −12

Step 3: Multiply both sides by 3.

3*( 1 /3 d) = (3)*(−12)

d=−36

Hope this helps! :}

Answer: C
First you have to get rid of the 8 because it is a constant. -4-8=-12. Then, you multiply out the denominator to isolate the variable. This means -12*3=-36

Find the circumference of a circle with an area of 530.93

HACTEHA [7]

A = π r^2
r^2 = A/π
r^2 = 530.93 / 3.14
r^2 = 169.08
r = 13

C = 2 π r
C = 2 (3.14)(13)
C = 81.64

answer
81.64 m

(-3/2x4/5)+(9/5-10/3)-(1/2x3/4)

Lynna [10]

$\left ( \frac{3}{2}\times \frac{4}{5} \right )+\left ( \frac{9}{5}- \frac{10}{3} \right )-\left ( \frac{1}{2}\times \frac{3}{4} \right )$

In the first parenthesis, multiply the numerators so we get -12 and after multiply the denominator we will get 10

So the fraction in the first parenthesis will be $\left ( \frac{-12}{10} \right )$

To solve the 2nd parenethesis, find the LCD of the denominator.

So the LCD of 5 and 3 = 15,

Now make the each denominator same as that of LCD.

So the new fractions in the 2nd parenthesis = $(\left ( \frac{27}{15}- \frac{50}{15} \right )$ = $\left ( \frac{-23}{15} \right )$

In the third parenthesis, multiply the numerators so we get 3 and after multiply the denominator we will get 8

So third parenthesis = $\left ( \frac{3}{8}\ \right )$

= $\left ( \frac{-12}{10} \right ) + \left ( \frac{-23}{15} \right ) -\left ( \frac{3}{8}\ \right )$

LCD of 12,15 and 8 is 120

= $\left ( \frac{-144}{120} \right ) + \left ( \frac{-184}{120} \right ) -\left ( \frac{45}{120}\ \right )$

= $\left ( \frac{-373}{120} \right )$
