Since 17 isnt a factor of 42 the only factor is 1
Answer:
Blank 1: 40
Blank 2: 10
Step-by-step explanation:
You can start by representing the speed of the water as x and the speed of the dolphin as y, and writing an equation.
y+x=50
y-x=30
Adding these two equations together, you get:
2y=80
y=40 for the speed of the dolphin in still water. Now, you an use one of the previous equations to find the speed of the current.
40-x=30
x=10
Hope this helps!
P(arrives on time given leaves on time)=
P(B | A)= P(B n A) / P(A)
= P(A n B) / P(A)
= 0.36 / 0.9
= 0.4
Answer: 
Step-by-step explanation:
Given the following equation:
You can follow these steps in order to solve for "x" and find its value:
1. Apply Distributive property on the right side of the equation:
2. Subract 
from both sides and add the like terms:
3. Subtract 1.8 from both sides:
4. Finally, divide both side of the equation by -1.5:
