▪ Answer:

n = 17

d = 8

▪ Step-by-step explanation:

Hi there !

1 nickel = 5c

1 dime = 10c

$1.65 = 165c

n + d = 25 => n = 25 - d

5n + 10d = 165

replace n

5(25 - d) + 10d = 165

125 - 5d + 10d = 165

5d = 165 - 125

5d = 40

d = 8 (dimes)

n = 25 - d

n = 25 - 8

n = 17 (nickels)

Good luck !

STALIN [3.7K]
First you must convert the weight from pounds to kg. 50 pounds is 22.7kg. You divide 50 by 2.2 to get that. Then you woukd divide what was ordered by what you have on hand 1.5÷75x ml. It would equal 0.02.

Answer:

D) 12,656

Step-by-step explanation:

First of all, as they have given us 3 quantities of plants in 1/2 an acre, we can work out the average amount of plants in 1 whole acre.

In the first 1/2 acre there were:

  • 291 plants

In the second 1/2 acre there were:

  • 327 plants

In the third 1/2 acre there were:

  • 286 plants

to work out the average, we add all these together then divide them by 3 (as there are 3 examples)

291 + 327 + 286 = 904

904 ÷ 3 = 301.3 (this is the average amount of plants in every 1/2 acre.) If we multiply this answer by 2 we will get the average amount of plants in every acre.

301.3 x 2 = 602.67 (average plants in every 1 acre) multiply by total acres (21) for your answer

602.67 x 21 = 12656 average plants in total

I hope this was helpful :-)
