Answer:
Bob swam 70 meters on Monday
Step-by-step explanation:
Let x = Meters swam on Monday
and y = Meters swam on Tuesday
x + y = 250
y = 250 - x
y = 3x - 30
250 - x = 3x - 30
4x = 280
x = 70
y = 180
Using the given equation:
10PI/X = 240/360
Cross multiply:
(10PI*360) = (240*X)
3600PI = 240X
Divide both sides by 240:
X = 3600PI / 240
X = 15PI in^2
Answer:
2.25 ounces
Step-by-step explanation:
22+11.2+16.3=49.5
49.5/22=2.25
Neither of them do,
The first one gives you:
1=-19
The second one gives you:
2=9
Neither of which are true.
Hope this helps :)
