u = fv/(v - f)
Step-by-step explanation:
1/f = 1/u + 1/v
1/u = 1/f - 1/v = v/fv - f/fv = (v-f)/fv
1/u = (v-f)/fv
u = fv/(v - f)

Option B. 16-8
Step-by-step explanation:
Let
z ------> the number of apple left
x -----> the total number of apples
y -----> the number of apples sold
we know that
The numerical expression of the phrase " the number of apples left if eight out of the sixteen apples have been sold" is equal to subtract the number of apples sold from the total number of apples
so
z=x-y
we have
x=16 apples
y=8 apples
substitute
z=16-8
Answer:
56:8:48
Step-by-step explanation:
1] add th eratio numbers together
7+1+4=12
2} write the ratio as fractions
7/12 1/12 4/12
3] use the formula (ration number/total number * number of sheeps)
a] 7/12 * 96 = 56
b] 1/12 * 96 = 8
c] 4/12 * 96 = 48
3] write your answer as a ration
7 : 1 : 4 = 56 : 8 : 48
