150 red bars, since 200 divided by 4 equals 50, then 3 x 50 would give u 150 red bars
150 lower level
200 upper level
Let x = lower level and y = upper level. You can then set up an equation for cost as:
35x + 25y = 10,250
and the equation for total tickets as:
x + y = 350.
Solve using any method.

since -x^2+x+19=y
<span>
</span>
x=-x^2+x+19+80
<span>
</span>
x=-x^2+x+99
<span>
</span>
0=-x^2+99
<span>
</span>
x^2=99
x=3√11
x=y+80
3√11=y+80
minus 80 both sides
-80+3√11=y
x=3√11
y=-80+3√11
solution
(x,y)
(3√11,-80+3√11)
Answer:
The missing angle is 128°
Because corresponding angles are equal.
The angle pair is called <em><u>corresponding</u></em><em><u> </u></em><em><u>angles</u></em><em><u> </u></em>
