So a deckameter is = to 10 meters
just multiply it
3*10= 30
then divide
30/1= 30
So glenn needs 30 meter paces of ribbon
For this one, use the order of operations to solve it, we called it PERMDAS to remember the steps.
14-6.2 times (-3+ -7)
So do the parenthesis first
-3+-7= -10
now the multiplication
-6.2 times -10= 62
a negative times a negative equal a 62
Now your problem is 14-62
Which equals -48.
So if I did my math and operations correctly, the answer would be B. -48.
Hope this helps!
