Adding to "undo" subtraction and subtracting to "undo" addition are both examples of using inverse operations to solve equations
. Think of another pair of inverse operations in mathematics. How do these inverse operations "undo" each other?
1 answer:
Answer:
see below
Step-by-step explanation:
Multiplication and division are also inverse operations
15 * 10 = 150
150 ÷10 = 15
Divide 150 by 10 and we get 15 back
The division undoes the multiplication
This also works in reverse
150 ÷ 10 = 15
15*10 =150
The multiplication undoes the division

Y=mx+b so it should be y=3x-4
Let x = number
2(x-2)=3(x+6)
2x-4=3x+18
2x-3x=18+4
-x=22
x=-22
Answer:
the side length of y is 6... sorry if that is incorrect
Answer:
B) 12p - 10
Step-by-step explanation:
J = 3p
A = 2(3p) = 6p
S = 3p - 10
add together:
3p + 6p + 3p - 10 = 12p - 10
