2x+8y = 6<br> 15x + 20y = 15

Answer:

The solution is (0, 3/4)

Step-by-step explanation:

Please copy and share the instructions. Here they are: Solve the following system of linear equations.

Both of the equations can be reduced (simplified):

2x+8y = 6 => x + 4y = 3

15x + 20y = 15 => 3x + 4y = 3

Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining

-x - 4y = -3

Add the second 3x + 4y = 3

equation to the

first.

We get: 2x = 0.

Thus, x = 0. Substituting 0 for x in the 1st original equation yields:

2(0) + 8y = 6. Then y = 6/8, or y = 3/4.

The solution is (0, 3/4).

Jeo is comparing the price of different boxes of cereal. One box has 16 oz. and costs $3.50. Another costs $3.89 for a 24 oz. bo

Answer:

The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.

Step-by-step explanation:

☆Let's solve using proportion.

☆One box:

$\frac{16 \: oz.}{3.50 \: dollars} = \frac{1 \: oz.}{x} \\ \\ \frac{3.50}{16} = \frac{16x}{16 } \\ \\ 0.22 = x$

☆Another box:

$\frac{24 \: oz.}{3.89 \: dollars} = \frac{1 \: oz.}{x } \\ \\ \frac{3.89}{24} = \frac{24x}{24} \\ \\ x = 0.16$

☆All we need to do is subtract: $0.22 - 0.16 = 0.06$

☆The difference in cost, in dollars, per ounce between the two boxes of cereal is $0.06.
