Answer:
{x,y}={−5,−7}
Explain:
// Solve equation [2] for the variable y [2] 3y = 7x + 14 [2] y = 7x/3 + 14/3 // Plug this in for variable y in equation [1] [1] 8x - 3•(7x/3+14/3) = -19 [1] x = -5 // Solve equation [1] for the variable x [1] x = - 5 // By now we know this much : x = -5 y = 7x/3+14/3 // Use the x value to solve for y y = (7/3)(-5)+14/3 = -7 Solution : {x,y} = {-5,-7}
Hoped I helped
Step-by-step explanation:
You can put the value of x into the equation to solve for y. Hopes this works.
Answer:
d = 1.67 miles
Step-by-step explanation:
Given that,
Speed of a person, 
We need to find how many miles can you walk in 30 minutes, given the same pace.
30 minutes = 0.5 h

Speed = distance/time

So, the person will cover a distance of 1.67 miles
