Very easy!
6 people= 12 servings so 1 person= 2 servings
We have 112 people so we need 112 x 2= 224 servings
So she will make 224 servings with an 8 servings pan, 224/8= 28 pans.
The minimum number of pans she need in order to serve 112 people is 28 pans!
Let other 2 angles be d
44 + 2d = 180°
(sum of triangle)
2d = 180 -44
2d = 136
d = 136/2
d = 68
x = 68 + 44 (exterior angle is equal to sum of interior opposite angles)
x = 112°
l
2. part
let the other angles be d
3d = 180° (sum of angles of triangle)
d = 60°
x = 60 + 60
x = 120°
Answer:
Age of younger brother is 14 years..
And age if elder brother is 29 years.
Step-by-step explanation:
Let us denote 'x' as the age of smaller brother,
then, the age of younger brother will be x+15 years.
Equation formed:-
x+x+15 =43
2x+15 = 43
2x = 43-15
2x = 28
X = 28/2
X = 14
Age of younger brother is 14 years.
Age of elder brother = x + 15
Age of elder brother 14 + 15 = 29 years.
