0.2(d − 6) = 0.3d + 5 − 3 + 0.1d. Help needed

Answers

Answer 1

Answer:

$\text{Solve for d}\n\n0.2(d − 6) = 0.3d + 5 − 3 + 0.1d\n\n\text{Combine like terms:}\n\n0.2(d - 6) = 0.4d + 2\n\n\text{Use the distributive property:}\n\n0.2(d - 6) = 0.4d + 2\n\n0.2d-1.2=0.4d+2\n\n\text{Subtract 0.4d from both sides}\n\n-0.2d-1.2=2\n\n\text{Add 1.2 to both sides}\n\n-0.2d=3.2\n\n\text{Divide both sides by -0.2}\n\n\boxed{d=-16}$

How would you solve 7 - 3y = 22

Answers

7-3y=22 -7 -7 -3y=15 Divide by -3. y=-5

22+-7=15 3y = 15 then
Divide each side by '3'. y = 5
Simplifying y = 5
so your answer is going to be 5

Which expression is equivalent to sin7pi/6?A. sinpi/6
B. sin5pi/6
C. sin5pi/3
D. sin11pi/6

Answers

For this case we must find an expression equivalent to:

$Sin (\frac {7 \pi} {6})$

According to the unit circle, $\frac {7 \pi} {6}$ is in the third quadrant and equals 210 degrees.

Then, we must find an expression equivalent to:

$Sin (210) = - \frac {1} {2} = - 0.5$

We have to:

$\frac{11 \pi} {6}$

It is in the fourth quadrant and is equivalent to 330 degrees, according to the unit circle.

$Sin (330) = - \frac {1} {2} = - 0.5$

Answer:

Option D

The answer choice is D because sin7pi/6 which it’s exact form is -1/2 the only answer choice which the same exact form is D.
