Answer:

y = 9  when  x = 4

Step-by-step explanation:

If  y  varies inversely as  x  then XXX x ⋅ y = c  for some constant  c  

Given  y = 12  when  x =3  XXX 3 ⋅ 12 =c

XXX ⇒ c = 36  

So XXX x ⋅ y = 36   and when  

x = 4  

XXX 4 *y = 36  

XXX ⇒ y = 9

The ratio of duck eggs to chicken eggs in an egg store is 2:7.If there are 312 duck eggs in the store.how many chicken eggs are
daser333 [38]

Answer:

x = 1,092

Step-by-step explanation:

Duck eggs : chicken heads =

2 : 7

Number of duck eggs = 312

Number of chicken eggs = x

Duck eggs : chicken heads = 312 : x

Equate both ratios

2 : 7 = 312 : x

2/7 = 312/x

Cross product

2 * x = 7 * 312

2x = 2,184

x = 2,184 / 2

= 1,092

x = 1,092
