<span>1) Solve the system of equations using the substitution method.
2x+8y=4
x=−3y+5
we have that
</span>2(−3y+5)+8y=4---------- > -6y+10+8y=4---------- > 2y=-6-----> y=-3
x=−3y+5----------> x=−3*(-3)+5=14
the answer is
x=14
y=-3

Answer:316
Step-by-step explanation:
width=x
perimeter = 898
2( width + length ) = 898 , length = width + 183 = x + 183
width + length = 898/2
x + x + 183 = 449
2x = 449 - 183
2x = 266
x = 133
so,
width = 133
length = width + 183= 133 + 183 = 316
Assuming that you are referring to a football field, then 4 laps around it would be considered 1600 meters, which is 9.3 meters short of a mile. Depending on how fast you are running, I would say that it would take at least 2 or 3 seconds to make up that 9.3 to make it a full mile. I hope that this helps in some way or form!
