Answer:
30 first-class tickets were sold and 260 coach tickets were sold.
Step-by-step explanation:
Let a first-class ticket be represented by f and let a coach ticket be represented by c.
On a particular flight, a jumbo jet was carrying 290 passengers. So, the sum of the first-class tickets and coach tickets must sum to 290:

The total income was $95,280. Therefore:

We can now solve the system of equations. First, we can simplify the second equation by dividing everything by 8:

From the first equation, we can subtract f from both sides:

Substitute:

Distribute:

Simplify:

So:

From the previous equation:

Substitute:

30 first-class tickets were sold and 260 coach tickets were sold.

b
Step-by-step explanation:
In a 30-60-90 right triangle, the hypotenuse is twice the length of the short leg.
The hypotenuse is AB and is 18.
The short leg is BC and is 9.
The only choice with BC = 9 is b.
Answer: b
-24+12d=2d-6+22
-24+12d=2d+16
-24+12d+24=2d+16+24
12d=2d+40
12d-2d=2d+40-2d
10d=40
10d/10=40/10
D=4
