To expand this expression, we distribute the 7/10 to each term inside the parentheses:
7/10(5d+6) = (7/10)(5d) + (7/10)(6)
First, multiply 7/10 by 5d:
(7/10)(5d) = (7/10)(5)(d) = (35/10)(d) = 3.5d
Next, multiply 7/10 by 6:
(7/10)(6) = (7/10)(6/1) = (42/10) = 4.2
Now, putting the results together:
7/10(5d+6) = 3.5d + 4.2
7/10(5d+6) = (7/10)(5d) + (7/10)(6)
First, multiply 7/10 by 5d:
(7/10)(5d) = (7/10)(5)(d) = (35/10)(d) = 3.5d
Next, multiply 7/10 by 6:
(7/10)(6) = (7/10)(6/1) = (42/10) = 4.2
Now, putting the results together:
7/10(5d+6) = 3.5d + 4.2
