marta [7]

Answer:

$3.34 for each pound of popcorn

This equals 3.34.

Therefore, each pound of popcorn cost $3.34.

Don't believe me? To check, just multiply 3.34 by 2.5.

Mrs. Bailey has equal numbers of nickels and quarters but the value of the quarters is $1.80 more than the value of the nickels.
sdas [7]

The total value of all coins together is $2.7

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction. When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line

Let the number of nickels and quarters be x.

Value of nickel = 5 cents = $0.05

Value of quarters = 25 cents = $0.25

Thus, the total value equals

0.05x +$1.80 = 0.25x

$1.80 = 0.25x - 0.05x

$1.80 = 0.2x

x = 1.80/0.2

x = 9 coins

Thus the total value of all coins together is  ($0.05+$0.25)x 9 = $0.3 x 9

= $2.7
