Answer:
around 21-8 so the equation would look like this (21-8)-6=7
Step-by-step explanation:
you do this because if u put the parentheses around 8-6 you would get 21- (8-6)= 19 because 21 - 2 = 19 so you have to put them around 21-8 to get the right answer
2/32 - 1/16 this is the probability (in fractions)
20%
This is because 20 and it's opposite -20 is 40. (20 - -20 = 40). Then 40 is 20% of 200.
Take 2x and add 1 to equal 113
2x+1=113
