Help pleaseee i need helpp

Given:

Total number of coins = 20

Total cost of nickel and dime = $1.40

To find:

The number of nickels.

Solution:

Let the number of nickels be "n" and number of dimes be "20 - n".

Value of nickel = 5 cents

Value of dime = 10 cents

$1.40 = 140 cents

Cost of nickel + Cost of dime = $1.40

Subtract 200 from both sides.

Divide by -5 on both sides.

Hence Jenna have 12 nickels.

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
