4xAnswer: y=9-4x
Step-by-step explanation: Subtract 4X from both sides
(1+tan²x)/(tan²x) =
1/tan²x + tan²x/tan²x =
cos²x/sin²x + 1 =
cos²x/sin²x + sin²x/sin²x =
(cos²x + sin²x) / sin²x =
1/sin²x =
csc²x.
QED
Answer:
17y+24
Step-by-step explanation:
simplify so the first step would be to multiply whats in the parentheses by the number outside in this case its 6 youd get:

Answer:
4. 6 cups
6. 50 dollars
7. 27000 words
8. 300 dollars
Step-by-step explanation:
4.
2 cups x cups
-------------- = -----------
6 people 18 people
Using cross products
2 * 18 = 6x
Divide by 6
36/6 =6x/6
6 =x
6.
12 cans 30 cans
-------------- = -----------
20 dollars x dollars
Using cross products
12x = 20*30
12x = 600
Divide by 12
12x/12 =600/12
x = 50
7.
3 hours = 3*60 minutes/hour = 180 minutes
30 minutes 180 minutes
-------------- = -----------
4500 words x words
Using cross products
30x = 4500*180
Divide by 30
x = 4500*180/30
x=27000
8.
45 dollars x dollars
-------------- = -----------
15 burgers 100 burgers
Using cross products
45*100 = 15x
Divide by 15
45*100/15 = x
300 =x
