Lets assign some variables: Let
y = Darren + Michael
x = Brian.
Given:
y = 2x + 30 (Darren and Michael [y] earn [=] 30 more than[+30] twice what Brian earns[2x])
y = 3800 (Darren and Michael [y] earn [=] $3800)
Solve for x: What Brian earns.

I will solve this by substitution. Plugging in 3800 for y:
3800 = 2x + 30 subtract 30 from both sides
3770 = 2x divide by 2 on both sides
1885 = x flip the equation
x = 1885
Brian earns $1885 per month.

20 points!!! first answer gets brainliast. Don't need too much explanation thank you!​

Answer:

The answer to your question is below

Step-by-step explanation:

2. \sqrt{-128}                Just find the prime factors of 128 and simplify

   \sqrt{-2^{7}} = \sqrt{-2^{6} 2} = 2^{3}i \sqrt{2}

   8i\sqrt{2}

3.- \sqrt{-9} + \sqrt{-16}     Get the square roots and simplify

     3i + 4i

     7i

4.- None of the choices is equal to one, because the exponents are pair.

5.- 1/3x² + 10 = 7

    1/3x² = 7 - 10

    1/3x² = -3

         x² = -3(3)

         x² = -9

         x = ±3i

BEST ANSWER GETS BRAINLY (EMERGENCY)
MrRissso [65]

Answer:

Part A: 5

Part B: 2

Step-by-step explanation:

to find the mean all you have to do is add all the numbers together and then divide it by how many numbers there are in the data set

3+4+4+4+5+6+6+8=40

40÷8=5

so the mean is 5

next to find the mean of absolute deviations you need to subtract each number in the data set from the mean then divide it by how many numbers are in the data set (if you get a negative like 6-5=-1 just take away the negative sign to make it positive)

5-3=2

5-4=1

5-4=1

5-4=1

5-5=0

6-5=-1

6-5=-1

8-5=-3

2+1+1+1+0+1+1+3=10

10÷5=2

so the mean absolute deviation is 2
