Given:
w varies jointly as x and y.
w=10 when x=2 and y=1.
To find:
The value of w when x=4 and y=2.
Solution:
w varies jointly as x and y.
...(i)
Where, k is the constant of proportionality.
w=10 when x=2 and y=1.
The value of k is 5.
Putting k=5 in (i), we get
To find the value of w when x=4 and y=2. Put x=4 and y=2.
Therefore, the value of w is 40 when x=4 and y=2.
Answer:
The first one is 35 5/6. The second is 8 1/3
Step-by-step explanation:
5/1 * 7 3/6
= 5/1 * 45/6
=215/6
= 35 5/6
3 1/3 * 2 2/4
= 10/3 * 10/4
= 100/12
= 8 1/3
32 in. because 2.5 feet is only 30 in
694/54=12 with remainder 46 ( Answer is 12 R 47)
