2(s+3)=4s-5
2s+6=4s-5
4s-2s=5+6
2s=11
s=5,5
15 (20)+6(60-20)= 240
15 (30)+6(60-30)=630
15(40)+6(60-40)=720
you can conclude that none of the numbers have anything in common except that they all end in a 0
Answer:

Step-by-step explanation:
=> Since it is an equilateral (Having all angles and all sides equal) triangle, so every angles will be equal to the other.
=> The sum of the measures of interior angles of triangle add up to 180 degrees.
So,
3x + 3x + 3x = 180
9x = 180
Divide both sides by 9
x = 20

Answer:
- 2x + y
- 3 x - 2y
- -1
2(3 x - 2y) = -6x + 4y
2x + y + -6x + 4y + -1 = -4x + 5y -1
I can show you on a piece of paper
Hope this helps *smiles*
