Answer:
10, there will be 20 left open
Step-by-step explanation:
if each bus holds 42 students and there are 400 going then you need to divide 400 by 42, and then round up, to find how many seats will be left open, you take the answer and then multiply it by 42 and then subtract 400.
sorry for not putting my work last time.
Answer:
292.5 miles per day
Step-by-step explanation:
The map shows it is 1170 miles from my school to Wall, South Dakota, a place well-advertised in the Midwest. If I want to take 4 days to get there, the required division is ...
... (1170 mi)/(4 da) = 292.5 mi/da
Put parentheses around 4-6. all that would equal -55*-2 /2. i would equal 55. idk if this helps but here you go
The pic is blurry, but looks like 18x²-21x-15
(3x-5)(6x+3) is the factored form.
3 and 6 are the factors of 18
-5, 3 or -3, 5 are the factors of -15
I line them up like this
3 -5
6 3
then I multiple them diagonally: 3*3=9, -5*6=-30, the sum of 9 and -30 is exactly -21, the coefficient for x. (If the sum doesn't make -21, I'd switch -5 and 3, or change to -3 and 5 to try again.)
so the factored form is (3x-5)(6x+3)
