1a)
5 green circles
1 green square
2 red circles
4 red circles
1b) probability is 5/12
Step-by-step explanation:
count for each (1a)
count every shape=12
since there is 5 green circles
the probability is 5/12
You set it equal to 0 then solve. you would move 4 over to the other side so you would have 1/5w=-4 then multiply -4 by the opposite of 1/5 which is 5. and you get
w= -20
Answer:
67
Step-by-step explanation:
Number: AB
A = B-1
BA + AB = 143
10*B + A + 10*A + B = 143
11A + 11B = 143
A + B = 13
(B-1) + B = 13
2B = 14
B = 7
A = 6
The number is 67
check: 6 = 7-1 and 67 + 76 = 143
