38=3d+8

38-8=3d+(8-8)

30=3d

30/3=3d/3

10=d

=3d+

Your answer would be D=10 because you move the like terms Move variable to the left-hand side and change its sign then Move constant to the right-hand side and change its sign then calculate the difference last thing you do is Divide both sides of the equation by

Rice weighing 33/4 pounds was divided equally and placed in 4 containers. How many ounces of rice were in each?

QveST [7]

Answer:

The answer is 15 ounces

Step-by-step explanation:

33/4 ÷ 4 pounds.

(4 × 3 + 3)/4 ÷ 4 pounds.

15/4 ÷ 4 pounds.

15/4 × 1/4 pounds.

15/16 pounds.

Now we know that, 1 pound = 16 ounces.

So, 15/16 pounds = 15/16 × 16 ounces = 15 ounces.

Thus, The answer is 15 ounces

For the following system, if you isolated x in the first equation to use the substitution method, what expression would you subs

alekssr [168]

Answer:

$x=2y+6$

Step-by-step explanation:

So we have the system:

$-x+2y=-6\\3x+y=8$

If we isolate the x-variable in the first equation:

$-x+2y=-6$

Subtract 2y from both sides:

$-x=-6-2y$

Divide both sides by -1:

$x=2y+6$

Therefore, we would substitute the above into the second equation:

$3x+y=8\\3(2y+6)+y=8$

The answer is 2y+6

Further notes:

To solve for the system, distribute:

$6y+18+y=8$

Simplify:

$7y+18=8$

Subtract:

$7y=-10$

Divide:

$y=-10/7\approx-1.4286$

Now, substitute this value back into the isolated equation:

$x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429$

Identify this problem plssss

JulsSmile [24]

Answer:

The answer is cot(x)

Step-by-step explanation:

<h3>Greetings !</h3>

$\tan(x) \csc {}^{2} (x) - \tan(x)$

Rewrite using trig identity

$- \tan(x) + \csc {}^{2} (x) \tan(x)$

use the Pythagorean idea

$\csc {}^{2} (x) = 1 + \cot {}^{2} (x)$

$- \tan(x) + (1 + \cot {}^{2} (x)) \tan(x)$

simplify

$\cot {}^{2} (x) \tan(x)$

use basic trigonometric identity

$\tan(x ) = \frac{1}{ \cot(x) }$

simplify

$\cot {}^{2} (x) \frac{1}{ \cot(x) }$

gives you

$\cot(x)$

Hope it helps!

A bag contains 4 red balls and 6 blue balls. If 3 balls are selected at random, find the probability of selecting 3 red balls?

Paha777 [63]

The probability is 4⋅3⋅2⋅1/10•9•8•7=(4/4)(6/0)/(10/4)=1/210 so the probability of selecting 3 red balls would be 1/210
