Answer:
John has 12 pokemon cards
Kevin has 60 pokemon cards
Step-by-step explanation:
let x = the # of pokemon cards John has
5x = the # of pokemon cards Kevin has
5x + x = 72
6x = 72
x = 12
5x = 60
1 3/8 in one week
B. 30
3x + 2x + x = 180 (angle sum of a triangle is 180)
6x = 180
x = 30
The additive inverse: The usage of addition with a negative number.
The original equation is 21 - 11 = 10
To use the additive inverse, change it so that there is an addition sign.
21 + (-11) = 10
B) -11 is your answer
