Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
1/3*3.14= 1.046666666 ect.

Explanation: I guessed and it was right
Answer:
20
Step-by-step explanation:
d = √(xb - xa)2 + (yb - ya)2 =
= √(18 - 2)2 + (15 - 3)2 =
= √162 + 122 = √256 + 144 =
= √400
= 20
