45,90,135,180 you divide 360 by 8 so every 45 degrees it maps over it
Answer:
Single digit natural number can't be write in scientific notation.
We write very large and long positive number into scientific notation because it's easy to read.
We can't write negative number into scientific notation.
Step-by-step explanation:
Single digit natural numbers are 1,2,3,4,5,6,7,8,9
Scientific Notation: 
where,
k is between 1 to 9 , i,e 
n is any integers.
Example: Write in scientific notation
1) 5869742000
Scientific Notation: 
2) 0.000000849
Scientific Notation: 
The perimeter of a rectangle is just the sum of the lengths of its sides, so<span>taking half of each of the sides would make the total half of its original value also. </span>

Answer:
a) x = 10 + -1.5y
b) y+15
Step-by-step explanation:
a)2x+3y=10*√4
2x+3y=20
2x + 3y + -3y = 20 + -3y
2x + 0 = 20 + -3y
2x = 20 + -3y
x ÷ 2 = (20 + -3y) ÷2
x = 10 + -1.5y
b)x+2y+5*3=x+y
x+2y+15=x+y
x+2y+15 - y=x+y - y
x+y+15 =x
x+y+15 - x =x - x
y+15
