Answer:
(-6,4)
Step-by-step explanation:
make sure x's or y's are the same and opposite signs
x + 2y = 2 and -2x +y = 16
multiply 2 with x + 2y = 2 so that there is 2x
2 * (x + 2y = 2) = 2x + 4y = 4
2x + 4y = 4
-2x +y = 16
--------------------
5y = 20
y = 4
put y = 4 back into one of the equations
-2x +y = 16
-2x + 4 = 16
-2x = 12
x = -6
Answer:
Step-by-step explanation:
Amount of calories per hour whkie riding = 236
Amount of calories she intends to burn = 590
The number of hours she must ride her bike :
Let number of hours = x
Hence,
(Calories burned per hour * number of hours) ≥ 590
(236 * x) ≥ 590
x ≥ 590 / 236
x ≥ 2.5
Hence she must rise her bike for 2.5 hours
