Answer:
15 liters
Step-by-step explanation:
Given:
We need 5 liters of Yoda soda for 12 guest.
To find:
If we have 36 guest how many liters of Yoda soda we need.
Solution:
<u>By unitary method:</u>
For 12 guests, we need liters of Yoda soda = 5
For 1 guest, we need liters of Yoda soda =
For 36 guests, we need liters of Yoda soda =
Therefore, we need 15 liters of Yoda soda for 36 guests.
Answer:
x = and y =
Step-by-step explanation:
Known that he sum of angles on a straight line is . From the diagram;
2y + x + y =
x + 3y = ................ 1
Also,
2x + x + 2y =
3x + 2y = .............. 2
Using the elimination method, multiply equation 1 by 3 and equation 2 by 1
3x + 9y = 540 ............ 3
3x + 2y = ............. 4
7y = 360
y =
y =
substitute the value of y in equation 1,
x + 3y =
x + 3(51.4) =
x + 154.2 =
x = - 154.2
x =
Thus, x = and y =
