Sammy walks at 4 miles an hour for half an hour. This means the walk is 2 miles in 30 minutes.
Candy is going 6 miles an hour, so it will only takes her 1/3 of an hour, or 20 minutes, to cover 2 miles.
So, Candy gets home 10 minutes faster (30-20) than Sammy.
Remove the brackets
-5a + 9b + 7a combine -5a and 7a
7a - 5a + 9b
2a + 9b Answer
Don't go any further. There is nothing else to do. These are unlike terms and cannot be reduced or combined.
We start with 3: it stays unchanged
3.
then the first decimal place also remains unchanged:
3.6
now the second decimal place:
3.61
does it remain unchanged? No! the number AFTER is is 5 or bigger (it's 7), so we need to round it up. the answer is this:
3.62
Given is a parallelogram whose base is b = 10 inches and it says height is 2 more than half-value of base i.e. h = 2 + (b ÷ 2).
So height is h = 2 + (10 ÷ 2) = 2 + 5
⇒ h = 7 inches.
We know the formula for area of parallelogram is given as follows :-
Area of parallelogram = base x height
Area of parallelogram = 10 inches x 7 inches
Area of parallelogram = 70 squared inches.
Hence, the final answer is 70 squared inches.
