Answer:
(x, y) = (2, 1)
Step-by-step explanation:
given the 2 equations
2y - 3x = - 4 → (1)
6y + x = 8 → (2)
multiplying (2) by 3 allows the x terms to be eliminated
18y + 3x = 24 → (3)
add (1) and (3) term by term
(2y + 18y) + (- 3x + 3x) = (-4 + 24)
20y + 0 = 20 ( divide both sides by 20 )
y = 1
substitute y = 1 into either of the equations and solve for x
using (2), then
6 + x = 8 ( subtract 6 from both sides )
x = 2
solution (2, 1)
Answer:
approximately $27K
Step-by-step explanation:
Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
<em>Distance B = 1275 km</em>
