The answer is D. say you have 21 split into 5 parts then you will have 5 4.2's. then take three of them and you get 12.6.
Answer:
D = -6
Step-by-step explanation:
divide -5 by each side of the equation
W=kxp
where
k is the constant of proportionality given by:
k=w/xp
<span> If w=78 when x=2 and p=10 then
</span>k=78/(2*10)
k=3.9
thus the formula is:
w=3.9xp
b] <span>find x when w=858 and p=5.5
plugging the values in the formula we get:
858=3.9</span>×5.5×x
hence
x=858/(3.9×5.5)
x=358/21.45
x=16.69
There are 22 fourths in 5 1/2
