Well if you divide 226/2 you will get 113. o do 113x8= and you will get 904. So the plane will travel 904 miles in 8 hours!
Adult ticket= $6.00 Child ticket= $3.00
Total=$168.00
$6 x 17 people=$102 $3.00 x 17 kids= $51 + 5 kids x$3=$168
Adult tickets sold= 17
Children's Tickets sold= 22
Answer:
- discriminant: 11
- solutions: -6, +5
Step-by-step explanation:
Comparing your equation to the standard form, we can find the values necessary to compute the discriminant:
x^2 +x -30 = 0
ax^2 +bx +c = 0
So, we have ... a = 1, b = 1, c = -30
The discriminant is defined as ...
d = √(b² -4ac) = √(1² -4(1)(-30)) = √121
d = 11
The solutions are ...
x = (-b ± d)/(2a) = (-1 ±11)/2
x = {-6, +5}
Step-by-step explanation:
ABC = 90
ABC = ABD + DBC
4x + 7x -9 = 90
11 x = 99
x = 9
ABD = 4X = 4×9 = 36
DBC = 7X -9 = 63 -9 = 54
