Solution :
Given that the area model that represents a quotient of 108 ÷ 9.
So, we multiply 9 by multiples of 
to 
10 20 30 40
90 180 270 360
Because 108 is between 90 and 180, the quotient lies between 10 and 20.
Using 10 as the first partial quotient in the area model for 108 ÷ 9,
9 x 10 = 90 , so 108 - 90 = 18
Now, 9 x 2 = 18, so 18 - 18 = 0
∴ 10 + 2 = 12
Therefore, the quotient of 108 ÷ 9 is 12.
Answer:
1. (12-5)
2. 7(ab)
3. 14
4. -4
5. 0
Step-by-step explanation:
1. rewrite using distributive property
answer: a(12-5)
2. the answer is 7(ab)
3. 9 plus 5 = 14
4. -4
5. 25 plus -25 will be 0
1540 ÷ 55 = 28
the payments would be made for 28 months, or 2 years and 4 months
Use the identity: 
and solve for 
. You get: 
Do the substitution on the left side to get:
Answer:
n stands for the unknown number
Step-by-step explanation:
It's the only variable in the equations, so it is the only one that can stand for any unknown.
