Four less than half n is equal to 37 less than twice n
Four less than $(1)/(2)$ n is = to 37 less than 2n
$(1)/(2)$ n - 4 = 2n - 37

Answer:

$(-7, -6)$

Step-by-step explanation:

Use the definition of midpoint:

$M=((x_(1)+x_(2) )/(2),(y_(1)+y_(2) )/(2) )$

And replace the known values in:

$(-1, -2)=((5+x_(2) )/(2), (2+y_(2) )/(2) )\n(-7, -6)=(x_(2) , y_2)$

Sarah wants to give the pizza delivery boy a 20 percent tip. If the pizza bill is $48.25, how much should she tip?

Answers

If Sarah orders a pizza worth of $48.25 and she wants to offer 20 percent of the bill, then she needs to calculate the 20 percent of the total bill. 20 percent of $48.25 = 9.65 That mean Sarah should give $9.65 tip to pizza delivery boy.

What is x?
3(x - 4) - 14 = 2(x - 7) + 6

Answers

$3(x - 4) - 14 = 2(x - 7) + 6 \n \n 3x - 12 - 14 = 2x - 14 + 6 \ / \ expand \n \n 3x - 26 = 2x - 14 + 6 \ / \ simplify \n \n 3x - 26 = 2x - 8 \ / \ simplify \n \n 3x = 2x - 8 + 26 \ / \ add \ 26 \ to \ each \ side \n \n 3x = 2x + 18 \ / \ simplify \n \n 3x - 2x = 18 \ / \ subtract \ 2x \ from \ each \ side \n \n x = 18 \ / \ simplify \n \n$

The final result is x = 18.

3(x - 4) - 14 = 2(x - 7) + 6
⇒ 3x+ 3(-4) -14= 2x+ 2*7+ 6 (distributive property)
⇒ 3x -12 -14= 2x -14+ 6
⇒ 3x+ (-12 -14)= 2x+ (-14+ 6) (combine like terms)
⇒ 3x -26= 2x -8
⇒ 3x -2x= -8+ 26 (inverse operation)
⇒ x= 18

Final answer: x= 18.
