Answer:
x = 7
Step-by-step explanation:
Rule: an even number of - signs written one after another produces a plus number.
So - - 3 = 3
The rule also lets you do something strange like
- - - - 4 = 4 but you hardly ever see this.
Rule: an odd number of minus signs produces a minus number.
x + 3 = 10 Subtract 3 from both sides.
x + 3 - 3 = 10 - 3
x = 7
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
Decimal= 0.22
44÷200=0.22
Fraction= 11/50
44/200÷2= 22/100
22/100÷2= 11/50
6×ax+6×by =6ax+6by =3a+2b,6×bx-6×ay=3b-2a=6bx-3a+2b
Circumference = 2πr
r = 9
Circumference = 2π(9)
Circumference = 18π
Circumference = 18(3.14)
Circumference = 56.52
Distance: 56.52 meters
