Answer:
Cyrus needs to order 3 full pizzas to feed his 11 friends .
Step-by-step explanation:
The number of friends invited = 11
Share of pizza for each friend = 1/4 pizza
Now, as 1 friend eats 1/4 of a pizza.
⇒ 11 friends eat = 
So, 11 friends can eat 2 .75 pizza.
Since pizza come as a whole number.
And 2. 75 is nearly equal to 3.00
Hence, Cyrus needs to order 3 full pizzas to feed his 11 friends .

Answer: x = 4, y = 3
<u>Step-by-step explanation:</u>
and 
Using substitution method we get:

Answer:
sin Φ/(sin Φ + cos Φ) = 12/17
Step-by-step explanation:
sin Φ = 12/13
then sin Φ + cos Φ = 12/13 + 5/13
= 17/13
So , sin Φ/(sin Φ + cos Φ) = 12/13 ÷ 17/13
= 12/13 × 13/17
= 12/17
