x-3 and x+5 we can't do anything with so next
5(x-3)=5x-15

2(x+5)=2x+10

5x-15+2=5x-13

(2x+10-9)=2x+1

(5x-13)-3(2x+1)
-3(2x+1)=-6x-3

5x-13-6x-3=-x-16

4(-x-16)=-4x-64

the answer is -4x-64

Mr king is going to paint his house. The paint costs 21.99$ a gallon or 93.65$ for a 5 gallon can. What would be the unit price
vampirchik [111]
Divide 93.65 by the 5 gallons.

93.65/5= 18.73

If me.king bought the larger container, the unit price would be $18.73 per gallon. 

21.99-18.73= 3.26

The savings is $3.26 per gallon.

I hope this helps!

The difference between two same-side interior angles of two parallel lines is 35 degrees. Find the measures of these two angles.
Leona [35]

Answer:

angle 1:    72.5°

angle 2:   107.5°

Step-by-step explanation:

x + y = 180

x - y = 35         ===>      x = 35 + y

Substitution to find angle y:

  x + y = 180

  (35 + y) + y = 180

  35 + 2y = 180

  2y = 145

  y = 72.5

Substitution to find angle x:

  x = 35 + y

  x = 35 + (72.5)

  x = 107.5
