It takes 63 pounds of seed to completely plant a 7 acre field. How many acres can be planted per pound of seed?
Phantasy [73]

0.11 acres can be planted per pound of seed

<em><u>Solution:</u></em>

Given that it takes 63 pounds of seed to completely plant a 7 acre field

To find: acres can be planted per pound of seed

Let "x" be the acres which can be planted per pound of seed

Therefore, from given question,

63 pounds of seed = 7 acre field

1 pound of seed = "x" acre field

This forms a proportion and we can solve the sum by cross multiplying

Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction

Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction

Set the two products equal to each other

Solve for the variable

63 \times x = 7 \times 1\\\\63x = 7\\\\x = \frac{7}{63} = 0.11

Thus 0.11 acres can be planted per pound of seed

Can someone help me out ​
12345 [234]

Answer:

g - 16 is the answer

Step-by-step explanation:

−2 (3g−8g+8) − 9g

Distribute:

= (−2) (3g) + (−2) (−8g) + (−2) (8) + −9g

= −6g + 16g + −16 + − 9g

Combine Like Terms:

=−6g + 16g+ −16+ −9g

= (−6g+16g+−9g) + (−16)

=g+−16

Answer:

=g−16
