Answer:
a=5
Step-by-step explanation:
a^2+b^2=c^2
c^2-b^2=a^2

Answer:
Mid point is: (2.8;4.9)
Step-by-step explanation:
To find midpoint of a line segment we can use the general equation:

Where the point of the line are: (x₁;y₁) and (x₂;y₂).
In the problem, x₁ = 2.6, y₁ = 5.1 and x₂ = 3 and y₂ = 4.7. Replacing in the equation:

<h3>Mid point is: (2.8;4.9)</h3>
The anwer is b because you can multiply or subraction from it
<span>The Gonzalez family drove 342 miles in 6 hours. 342 ÷ 6 = 57 mph</span>
<span /><span>The Wilson family drove 472 miles in 8 hours. 472 ÷ 8 = 59 mph</span>
<span>So your answer is D. Wilson; 59 mi/h</span>
