Answer:
Value of r-w in terms of a is:
r-w= [tex]\dfrac{28}{5}a[/tex]
Step-by-step explanation:
We are given that:
r=5w=7a
We have to find the value of r-w in terms of a
r-w=5w-w (Since r=5w)
= 4w
= [tex]4\times \dfrac{7}{5}a[/tex] (Since, 5w=7a)
=[tex]\dfrac{28}{5}a[/tex]
Hence, Value of r-w in terms of a is:
r-w= [tex]\dfrac{28}{5}a[/tex]
