S = D/t
120 = D / 0.5
D = 120*0.5
D = 60 km
S = D/t
70 = D / 2.5
D = 70*2.5
D = 175 miles
Answer: $50 per month
Step-by-step explanation: Take 400 and divide it by the amount of months.
The square root of (64/225) is the same as √64 / √225 .
That could make the whole thing easier.
Do you know what either of those separate square roots is ?
You're right ! I'm so impressed!
The square root of 64 IS 8, and the square root of 225 surely is 15 .
You really know your stuff !
So now, the expression is √64 / √225 = <em>8 / 15</em> .
Oh, I almost forgot, it has a negative sign before it. OK,so the answer is <em>- 8/15</em> .
5, -4. that might not be right, though
