Answer:
1. 1050
2. 200 x 5.25= C
3. 155 students
Step-by-step explanation:
1. 5.25 x 200= 1,050
2. you multiply 200 x 5.25 the c is the unknown cost
3. To find how many tickets were purchased you need to divide 813.75 by 5.25
Answer:
a) 22.8%
Step-by-step explanation:
(2590-2000) ÷ 2590 =
590 ÷ 2590 =
.2277 = 22.8%
5x=25 could be one.
25/x-3=2 is another.
And the last one could be x/85+7=24
Answer:
The answer is tan²Ф + 1 = sec²Ф
Step-by-step explanation:
∵ sin²Ф + cos²Ф = 1 ⇒ ÷ cos²Ф both sides
∴ sin²Ф/cos²Ф + cos²Ф/cos²Ф = 1/cos²Ф
∵ sin²Ф/cos²Ф = tan²Ф
∵ 1/cos²Ф = sec²Ф
∴ tan²Ф + 1 = sec²Ф
It's 6/12 then 1/2. Good luck
