I like to put the variable in the numerator of a proportion. Here, we can write it as ...
t/12 = 45/90
Multiplying by 12 gives ...
t = 12(45/90) = 12(1/2) = 6
It will take Darin 6 hours to mow 12 lawns.
Answer:
x =3, y =3
Step-by-step explanation:
From the second equation( y= -x+6) we can get x alone.
Subtracting 6 from both sides we get, y-6 = -x
And then dividing both sides by -1, -y+6 = x
Then we can substitute this value of x into the first equation.
y = 2(-y+6) +3
Simplifying,
y = -2y + 12+ 3
3y = 15
y = 3
Substituting this back into second equation we get 3 = -x + 6
and -x = -3
Dividing both sides by -1,
we get x =3
