For this case we have the following quadratic equation:
The solutions will be given by:
Where:
Substituting the values we have:
We have two roots:
ANswer:
The first one is : x=<span><span><span>3/2</span>y</span>+<span>21/<span>2
the second one is: </span></span></span>x=<span><span><span>1/3</span>y</span>+<span><span>−7/</span><span>6</span></span></span>
Hey there,
#1 is D: 18 men and 30 women. The equation is: 12*m=48
#2 is B: Kathy drove 9 hours and Brain drove 3 hours. The equation is: 65m+55m/12=750
#3 is C: $0.86. The equation is: 2b+1h+1b+2h=8.52
