Step-by-step explanation:
Xy=10
x+y=29
subtract x from both sides for second equation
y=-x-29
subsitute in second equaiton
x(-x-29)=10
-x^2-29x=10
add x^2+29x to both sides
x^2+29x+10=0
quadratic formula
if you have
ax^2+bx+c=0,
x=

so
x^2+29x+10=0
a=1
b=29
c=10
x=
x=
x=

x=

x=

or

those are the 2 numbers
aprox=-28.65 and -0.349
Alright here's the breakdown:
it said every 4 miles <span>Vanessa jogged, Cody jogged 3 miles.
so
</span><span>Vanessa jogged 1 mile
that means
Cody jogged .75 of a mile ( or 75% of 1 )
because
Cody will always jog 75% of how much Vanessa joged
so say that
</span><span>Vanessa jogged 50 miles
all you do is take 75% of how much </span>Vanessa jogged
and that should be how much Cody joged
hopes this helps!
