Jamal works as an electrician’s apprentice. He rewired 4 electrical outlets in 1 1/2 hours. If he works at the same pace for 7.5
RSB [31]

This can be solve by first solving the proportionality constant

Number electic outlets rewired is directly proportional to time spent

4 = (1 ½)a

Let be the proportionality constant

A = 8/3

O = (8/3)(7.5)

o = 20 outlets will jamal rewired if he works for 7.5 hrs

Answer:

  750 < p < 1500

Step-by-step explanation:

The total cost of the affair for p attendees is ...

  750 +2.25p

The average cost is that number divided by p. The answer choices suggest that "between" means that the cost per person cannot be 2.75 or 3.25. Applying the limits to the average cost, we get ...

  2.75 < (750 +2.25p)/p < 3.25

  2.75 < 750/p + 2.25 < 3.25 . . . . . . . . separating the fraction parts

  0.50 < 750/p < 1.00 . . . . . . . . . . . . . . subtract 2.25

  2 > p/750 > 1 . . . . . . . . . . . . . . . . . . . . . take the reciprocal*

  1500 > p > 750 . . . . . . . . matches choice 4

_____

* Taking the reciprocals of numbers with the same sign reverses their order:

  2 < 3   but   1/2 > 1/3

__

An alternate approach to the solution would be to multiply by p:

  0.50p < 750 < 1.00p

To solve this requires it be made into two inequalities:

  0.50p < 750   ⇒   p < 1500

and

  750 < 1.00p   ⇒   750 < p

Then these would need to be recombined to form the answer:

  750 < p < 1500

What is the answer to this please help!
Butoxors [25]

z+(-0.72)=-2.5\\\\\text{Step 1}:\ x+(-0.72)+(-0.72)=-2.5+(-0.72)\qquad\text{ERROR}\\\\CORRECT\ IS:\ x+(-0.72)-(-0.72)=-2.5-(-0.72)\\\\\text{Step 2}:\ x=-2.5+0.72\\\\\text{Step 3}:\ x=-1.78


Subtract, not add, -0.72 from both sides.
