There are 7 chairs in each row length.
Step-by-step explanation:
Let number of chairs in 1 row be 'x'.
Let total number of chairs be 'y'.
Given:
Hue can form 6 rows of a given length with 3 chairs left over.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 6 plus number of chairs which is left which is 3.
Framing in equation form we get.
Also Given:
Hue can form 8 rows of that same length if she gets 11 more chairs.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 8 minus number of chairs which is required more which is 11.
Framing in equation form we get.
From equation 1 and equation 2 we can say that L.H.S is same.
So according to law of transitivity we get;
Combining like terms we get;
Using Subtraction and Addition property we get;
Now Using Division Property we will divide both side by 2.
Hence there are 7 chairs in each row length.
Answer:
d = 5/6t
Step-by-step explanation:
5 stories every 6 seconds
at 12 seconds, it would have travelled 10 seconds.
using this 2 data in this formula
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
Note : d = y, t = x;
d1 = 5, t1 = 6, d2 = 10, t2 = 12
we have
(d - 5)/(t-6) = (10-5)/(12-6)
(d - 5)/(t-6) = 5/6
d = 5/6(t-6) + 5
d = 5/6t -5+5
d = 5/6t
