Simplify 2/3 - 1/7 to 11/21
10/21 + 11/21
Simplify
The answer is 1.
The formula of a slope:

We have the points (-4, -3) and (-3, s) and the slope m = 3. Substitute:
The number of partial products Alan will have when he multiplies a 4-digit number by 36 is; 8 partial products.
First, we must establish that a 4-digit number will have 4 place values namely;
- Thousands
- Hundreds
- Tens
- Ones.
And since, 36 has 2 place values;
We can conclude that the number of partial products that Alan wil have is; 2× 4 = 8.

D because both sides have a length of 5
9/16 + 1/2 = 9/16 + 8/16 = 17/16 = 1 1/16
