Answer:
7 mph
Step-by-step explanation:
If b is the rate of the boat, and s is the rate of the stream, then:
b − s = 4
b + s = 10
Solve the system of equations with substitution or elimination. Using elimination, add the equations together:
2b = 14
b = 7
The boat's rate is 7 mph.
Answer:
the answer is commutative property
Step-by-step explanation:
commutative property is when both constants or variables don't change value when you move them from one side of the equal sign to another such as "a+b = b+a" or " a=b; b=a" both examples do not change value
Selection D) is appropriate.
The triangles are congruent by SSA, given the angle is a right angle, not ASA or AA. YX is not congruent to UW, so C) is incorrect.
