Answer:

The quantity of clover seeds in pounds to be added is 11.14

Step-by-step explanation:

Let

x -----> the quantity of poppy seeds in pounds

y -----> the quantity of clover seeds in pounds

we know that

24(x)+13(y)=20.70(x+y) -----> equation A

x=26\ pounds ----> equation B

substitute equation B in equation A and solve for y

24(26)+13(y)=20.70(26+y)

624+13y=538.2+20,70y

20.70y-13y=624-538.2

7.7y=85.8

y=11.14\ pounds

therefore

The quantity of clover seeds in pounds to be added is 11.14

Answer:

11.14 pounds ( approx )

Step-by-step explanation:

Let x pounds of poppy seeds and y pounds of clover seeds were mixed,

∵ Poppy seed costs 24$ per pound and clover seed costs 13.00$ per pound,

Thus the total cost of x pounds of poppy seeds and y pounds of clover seeds = 24x + 13y,

According to the question,

Resultant mixture costs $ 20.70 per pound,

∴ Total cost = 20.70(x+y),

\implies 24x + 13y = 20.70(x+y)

24x + 13y = 20.70x + 20.70y

24x - 20.70x = 20.70y - 13y

3.3x = 7.7y

\implies y = \frac{3.3}{7.7}x=\frac{3}{7}x

If x = 26,

y=\frac{3}{7}\times 26=\frac{78}{7}=11.1428571429\approx 11.14

Hence, 11.14 pounds of clover seeds should be added.

Is 2/3 equal to 2/4 because the numerator are equal
Masja [62]
No. For fractions to be equal, both the numerators and denominators have to be proportional.

Since both denominators are 2, the denominators would have to be just 3 or just 4.
