Answer:
70
Step-by-step explanation:
let x= no of children, y = no of parents, z= no of grandparents.
so according to question condition .... y = 2z, x= y+50 and x+y+z= 400.
hence on solving above all three equation....
x = no of children = 190 Answer
y= no of parents = 140 Answer
z= no of grandparents = 70 Answer
Answer:
x = 9, y = 4 and z = 6.67
Step-by-step explanation:
Since both the polygons are similar, by the property of similarity corresponding sides of the polygons will be proportional.
Therefore,
x =
x = 9
Similarly,
z =
z = = 6.67
And
y =
y = 4
Therefore, x = 9, y = 4 and z = 6.67 will be the values.
