Answer:

(5) 84° and 96° ; (6) 40° and 50°

Step-by-step explanation:

5) <em>Supplementary angles are in the ratio 7 : 8</em>

So 7x + 8x = 180°

15x = 180

x = 180/15

x = 12

The angles are 7x = 7 * 12 = 84° ; 8x = 8 * 12 = 96°

6) <em>Complementary angles are in the ratio 4 : 5</em>

So 4x + 5x = 90°

9x = 90

x = 90/9

x = 10

The angles are 4x = 4 * 10 = 40° ; 5x = 5 * 10 = 50°

Shalnov [3]

Answer: the price of one ticket is $70.

Step-by-step explanation:

The family of four went to a theme park and spent the total of $480 on tickets, food, and souvenir.

1/6 of their money was spent for souvenirs . It means that the amount of money that was spent on souvenirs is

1/6 × 480 = $80

1/4 of their money was spent for food. It means that the amount of money that was spent on food is

1/4 × 480 = $120

Total amount spent on souvenirs and food is

120 + 80 = $200

Total amount spent on tickets is

480 - 200 = $280

Since they are 4, the price of one ticket would be

280/4 = $70

Please help I need some one to answer this for me
sweet [91]
The last option is the correct option.
You basically just have to solve for e.
so multiply each side by 4 first.
that makes it 3e < 96
to get e by itself divide each side by 3.
which you e < 32
