Answer:
10 hours
Step-by-step explanation:
Two boats leave a port at the same time, one going north and the other traveling south.
<u>Southbound boat rate</u> = 40 mph
The northbound boat travels 18 mph faster than the southbound boat.
<u>Northbound boat rate</u> = 40 + 18 = 58 mph
Two boats rate = 40 + 58 = 98 mph (this means they are apart 98 km after one hour)
Total distance = 980 miles
Total rate = 98 mph
Time hours
Answer:
= -48
Step-by-step explanation:
3x^3 - 8y^2
3 ( 2 )^3 - 8 ( -3 )^2
first you solve the exponents
3 ( 8 ) - 8 ( 9 )
multiply
24 - 72
subtract
= - 48

Answer:
15
Step-by-step explanation:
First add 20 to both sides to get x/3 = 5
Then multiply both sides by 3 to get 15.
You can check it by substituting it into the equation
15/3 - 20 = -15
5 - 20 = -15
-15 = -15
3.1 miles left to go (3/3-2/3= 1/3, 1/3×9.3=3.1)
