Answer:
Rules & Examples of Integers multiplication.
Step-by-step explanation:
A rational number is a number that can be expressed as a fraction of integers (positive or negative numbers). Every integer is a rational number.
They are multiplied based on following rules :
- Positive (+) x Positive (+) = Positive (+) , +2 x +2 = 4
- Positive (+) x Negative (-) = Negative (-) , +2 x -2 = -4
- Negative (-) x Positive (+) = Negative (-) , -2 x +2 = -4
- Negative (-) x Negative (-) = Positive (+) , -2 x -2 = 4
Step-by-step explanation:
R' = (-2,0)
E' = (-2,2)
F' = (4,4)
Answer:
15+6x=75
Step-by-step explanation:
15 is the starting fee and it is 6$ per class so it would be 6x+15=75
Step-by-step explanation:
a) 6-9b=3a
First:Subtract
3b=3a
Second: Devide
3b/3a
=(3÷3)(b÷a)
=1b/a
= b/a
B) 6b+2a=3a
First:Transpose (Group the like terms. signs will change.)
-3a+2a=-6b
=-1a=-6b
Second:Divide
=-1a/-6b:(-1÷-6)(a÷b)
=1a/6b
=a/6b
C)a/3=b+2
First: Transpose
a=3+2+b
=a/6+b
