If you would like to rewrite the equation 3*x + 5*y = 7 so that y is a function of x, you can do this using the next few steps:

3*x + 5*y = 7
5*y = 7 - 3*x /5
y = (7 - 3*x) / 5
y = 7/5 - 3/5*x

The result is y = 7/5 - 3/5*x.

Ben and Susan are truck drivers who start at the same location. Ben drives 300 miles due west and Susan drives 160 miles due sou

Paul [167]

Answer:

Ben and Susan will be 340 miles apart

Step by Step Solution

Step 1: We plot the problem on a graph to visualize the problem

Step 2: We notice that the problem creates a right triangle with the distance Ben and Susan travel as the legs of the right triangle

Step 3: We can use the Pythagorean Theorem: a²+b²=c² to solve the distance between Ben and Susan

Step 4: We enter the numbers into the formula

a² + b² = c²

300² + 160² = c²

90000 + 25600 = c²

115600 = c² *square root both sides

c = 340

Therefore Ben and Susan are 340 miles apart
