Answer:
22w - 18
Step-by-step explanation:
To find the perimeter we have to add up all the sides
10w-10+w+1+10w-10+w+1
combine light terms
22w - 18 would be our answer
Answer:
2:3
Step-by-step explanation:
The common factor between 10 and 15 is 5.
5 goes into 10 twice and 15 three times.
÷ 
The sample space is {(1,H), (1,T), (2,H), (2,T), (3,H), (3,T), (4,H), (4,T), (5,H), (5,T), (6,H), (6,T)}
On the number cube, she could roll any of the numbers from 1 to 6. On the coin, she could flip heads or tails.
Answers are: 83 and 77
Notice how...
The jump from 98 to 97 is a decrease of 1
The jump from 97 to 95 is a decrease of 2
The jump from 95 to 92 is a decrease of 3
The jump from 92 to 88 is a decrease of 4
The pattern of decreases so far is: 1, 2, 3, 4
So the next decrease is 5
88-5 = 83
And the decrease after that is 6
83-6 = 77
