x+y = -19
x*y = 35
x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437
Ok so if I understand this correctly then you have to find out what each one of them are then add them to get the total number of both of them. So this is the equation I did. The one circled on blue is the formula I made for the equation and then the green one is the answer. which is 5 4/9
I hope this helps.
Answer:
the answer is attached in the picture
Assuming that she goes every day of the month and one month has 30days:
Let the fee per class of Fit Fast be x.
Let <span>the fee per class of Stepping Up be y.
Let </span><span>the fee per month of Stepping Up be z.
Fit fast fee(if she does for this choice) - 30x
Stepping up fee</span><span>(if she does for this choice) - 30y + z
Im not sure of what the costs are as you did not state but here it is...hope this helps:)</span>
