tamaranim1 [39]

X= number of student tickets

Y= number of on student tickets

x+y=311

0.50x + 1.50y = 385.50

Solve x in 1st equation

X+y=311

X= -y + 311

Now substitute x into second equation to solve for y

0.50(-y+311)+ 1.50y = 385.50

-0.50y+311.50+1.50y=385.50

Y+311.50=385.50

Y= 385.50-311.50

Y= 74

Now substitute y answer to first equation to find x

X+y=311

X+ 74=311

X= 311-74

X= 237

So 237 students tickets and 74 non students tickets

Solve 0= 2t^3-21t^2+ 40t

sukhopar [10]

$0=2t^3-21^2+40t$
switch sides
$2t^3-21t^2+40t=0$
solve factoring
$t(t-8)(2t-5)=0$
using the zero factor principle
$t=0
$
solve
$t-8=0:t=8$
solve
$2t-5=0:t= \frac{5}{2}$
$t=0,t=8,t= \frac{5}{2}$
Hope this helps

Answer:

+$90;

$1,600

Step-by-step explanation:

The equation, $y = 1600 + 90x$ , given to us tells us much about the situation described above.

y = total pay

x = number of copies of Math is fun

1600 = y-intercept, that is the starting value or the pay he gets only if Sam sold 0 copy of Math is fun. That is, when x = 0, y = 1,600.

90 = unit rate or the change in the total pay for each copy of Math is fun that Sam sells.

Therefore, our answers would be:

+$90, and $1,600
