5y = 5
Step-by-step explanation:
-2(x -2y) +(2x +y) = -2(-1) +(3) . . . . -2 times [eq2] + [eq1]
-2x +4y +2x +y = 2 +3 . . . . eliminate parentheses
5y = 5 . . . . . . . . collect terms
Answer: 5 miles
<u>Step-by-step explanation:</u>
Jogging West and then North forms a 90° triangle where 3 miles West and 4 miles North are the legs. Use the Pythagorean Theorem to find the hypotenuse.
a² + b² = c²
(3)² + (4)² = c²
9 + 16 = c²
25 = c²
√25 = √c²
5 = c
