Expand 7/10 * (5d + 6)
7/2 * d + 21/5
O 5d + 21/5
O 35d + 6
O 35d + 42
To expand the expression 7/10 * (5d + 6), distribute 7/10 to each term inside the parentheses:
= 7/10 * 5d + 7/10 * 6
= (7/10) * 5d + (7/10) * 6
= (7/10) * 5d + (7/10) * 6/1
= 35d/10 + 42/10
= 35d/10 + 42/10
Now, let's simplify the fractions:
35d/10 can be written as 7d/2
42/10 can be simplified to 21/5
Therefore, the expanded expression is:
7d/2 + 21/5, which is represented as:
7/2 * d + 21/5.
