Answer:

1. x=6

2. C <-26

3. p<6

4. -5x-44

Step-by-step explanation:

1. 2x = 3(x-2) - 3(x-6)

Distribute

2x= 3x-6 -3x+18

Combine like terms

2x =12

Divide by 2

2x/2 =12/2

x=6


2. C+6<-20

   Subtract 6 from each side

C+6-6 < -20-6

C <-26


3. -5p > -30  

Divide by -5.  Remember to flip the inequality when dividing by a negative

-5p/-5 < -30/-5

p<6


4. -4 - 5(X+8)

Distribute

-4 -5x-40

Combine like terms

-5x-44

Your sock drawer in all mixed up! You
Makovka662 [10]

Step-by-step explanation:

There are 21 socks in total. Only 7 of them are white.

When you pick your 1st sock, you have a 7/21 chance to get white.

When you pick your 2nd sock, you have a 6/21 chance to get another white, since you already picked a white.

So the probability to get a pair of white socks is 2/21.

Mark incorrectly solved the inequality -4(5/2+3/2x) &gt; 8. His work is shown. Which step shows an error based on the inequality
aliya0001 [1]

Answer : The incorrect step is, (A) step 1: -10 + 6x > 8

Step-by-step explanation :

The given expression is:

-4(\frac{5}{2}+\frac{3}{2}x)>8

Now solving this expression step by step.

First -4 distributed over parentheses.

(-4\times \frac{5}{2})+(-4\times \frac{3}{2}x)>8

Now solving bracket term, we get:

-10-6x>8

Now taking like terms together, we get:

-6x>8+10

-6x>18

-x>3

Now multiplying this expression by (-1), we get:

x>-3

Thus, the incorrect step is, (A) step 1: -10 + 6x > 8

Please help with the picture below
elena-s [515]

Answer:

Step-by-step explanation:

Remark

The angles are marked as alternate interior angles. To be parallel, they must be equal. In other words x - 20  must equal 52. That's all you have to do. Just equate the 2 givens and solve.

Givens

x - 20 is one angle

52 is the other.

Solution

x - 20 = 52                   Add 20 to both sides.

x - 20 + 20 = 52 +20   Combine

x = 72
