Since x=-1 and y=3
ax-2y=4
a(-1)-2(3)=4
-a-6=4
-a=10
a=-10
5x+by=-1
5(-1)+b(3)=-1
-5+3b=-1
3b=4
b=4/3
Answer:
72% = 72/100 = .72
Step-by-step explanation:
Answer:
414,000
Step-by-step explanation:
When rounding to the nearest thousand, you need to focus on the hundreds column. Because the unit is 5, you round up (5,6,7,8,9 determine rounding up). Therefore the 3 in the thousands column becomes a "4".
So it must have side length √16 = 4 cm and diagonal length 4√2 cm.
Answer:
360°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 4, hence
sum of interior angles = 180° × 2 = 360°
