It would take 5 times because if it goes 4 times it would reach 255 miles but if it goes 5 times it will pass the amount.
Answer:
-3 does not belong because it is not an algebraic expression unlike the others.
75 meters
Step-by-step explanation:
5 x 30/2
= 5 x 15
= 75 meters
Δ = (8i)^2 - 4*(-25) => Δ = -36 +100 => Δ = 64 => x1 =(-8i + 8)/2 => x1 = -4i +4;
x2 = (-8i - 8)/2 => x2 = -4i-4; in this case, your solutions are complex conjugates.
X + y = 12 / x (-45);
Then, -45x - 45y = -540;
We have 80x + 45y = 645 and
-45x - 45y = -540
________________
35x = 105;
Finally, x = 105÷35;
x = 3;
y = 12 - 3;
y = 9;
