-Please solve the image below

Answers

Yes,this is a doozy.

                 -3 (y - 5)  =  15

Eliminate the parentheses on the left side:

                 -3(y) -3(-5)  =  15

                 -3y  + 15  =  15

Subtract 15 from each side: 

                 -3y  =  0

Divide each side by -3 :

                    y  =  0

What is the answer to 3(5x+1)+5(x+6)

Answers

3 ( 5 x + 1 ) + 5 (x + 6 ) 

3* 5 x + 3 *1 + 5*x + 5*6

15 x + 3 + 5 x + 30

15 x + 5x + 3+30

= 20 x + 33

hope this helps!.
You are using the distributive property. You want multiply both the 5x and the 1 by 3 to get 15x+3 and then you want to multiply both the x and the 6 by five to get 5x+30. You are left with 15x+3+5x+30. Add together your likes, so 15x and 5x and 3 and 30. Your answer would be 20x+33. The easiest way to do you your math for equations like this is as following:

3(5x+1)+5(x+6)
15x+3+5x+30
20x+33

Write a number in which the digit 2 is one tenth the value of the the digit 2 in 8.524

A ceramic artist can shape a pot in 3 minutes. It takes 10 minutes to fire one batch of pots in the kiln. If there are p pots in a batch, which expression represents the time it takes to shape and fire one batch of pots? How long will it take the potter to form and fire a batch of 10 pots?The expression is 3p. It takes 30 minutes to shape and fire 10 pots.

The expression is 3p − 10. It takes 20 minutes to shape and fire 10 pots.

The expression is 3(p + 10). It takes 60 minutes to shape and fire 10 pots.

The expression is 3p + 10. It takes 40 minutes to shape and fire 10 pots.

Answers

3p + 10 (40 minutes)
3p+10. 3 minutes per pot to shape it. Time taken to shape all p pots is 3p. Then it takes 10 minutes to fire the batch. 

Use absolute value to express the distance between 10 and -4

Answers

Absolute value does not include direction, therefore, does not have a negative sign. Always positive.

The distance between 10 and -4 is 14.

I showed why in the attachment below. 

So, since we do not include the sign, your final answer is 14.

Final answer: 14
