Answer:
9 hours
Step-by-step explanation:
Let :
Landon hours = x
Ben hours = y
x + y = 14 - - (1)
60x + 56y = 820 - - - (2)
From (1)
y = 14 - x
60x + 56(14 - x) = 820
60x + 784 - 56x = 820
4x = 820 - 784
4x = 36
x = 36/4
x = 9
Landon drove for 9 hours
Answer:
Add 6,then add 7 , add 6,then add 20 and add 6 and add 46 and so on
EXPLANATION
Let's see the facts:
Thor ran ----> 30 laps
Shaq ran ---> 9 laps
Shaq ran 9 more laps than Thor, so the relationship is:
Shaq = Thore + 9
Shaq = 30 + 9 = 39
Answer: Shaq ran 39 laps around the lake.
Answer:
400% area and 200% perimeter
Step-by-step explanation:
Given is a picture of a rectangle. (i.e. opposite sides are equal and all angles equal to 90 degrees)
We know for any rectangle with length l and width, w
Area of rectangle = lw and
Perimeter of rectangle = 2(l+w)
Suppose the side lengths are doubled
Now length = 2l and width = 2w
New ARea =
i.e. 400% times is the new area.
New perimeter =
New perimeter is 200% times the old perimeter.
