10x - 7y = -1....multiply by -1 to make that -7y positive
-2x - 7y = -25
------------------
-10x + 7y = 1 (result of multiplying by -1)
-2x - 7y = -25
-----------------add
-12x = - 24
x = 2

-2x - 7y = -25
-2(2) - 7y = -25
-4 - 7y = -25
-7y = - 25 + 4
-7y = - 21
y = 3

solution is : (2,3)

Winne is currently considering two plans for paying for piano lessons.

SVEN [57.7K]

Answer:

Plan B

Step-by-step explanation:'

First u have to divide each one to see how much each piano lesson costs.

Plan A- 31.50/6=5.25

Plan B- 20.60/4=5.15

So since Plan B is less then Plan B would be the answer.

Given data:

$$1 \frac{4}{9} \text { and } 2 \frac{1}{3}$

Plot the points $1 \frac{4}{9} \text { and } 2 \frac{1}{3}$ on the number line.

Let us plot the first point $1\frac{4}{9}$ .

1 unit is completed. So count after 1 (indicated) in the number line.

point after 1 is $1\frac{1}{9}$

point after $1\frac{1}{9}$ is $1\frac{2}{9}$

point after $1\frac{2}{9}$ is $1\frac{3}{9}$

point after $1\frac{3}{9}$ is $1\frac{4}{9}$ .

So, move 4 points after 1 in the number line is $1\frac{4}{9}$ .

Now plot the point $2\frac{1}{3}$ .

To make the denominator 9, multiply and divide numerator and denominator by 3.

$$2 \frac{1}{3}=2 \frac{3}{9}$

2 unit is completed. So count after 2 (indicated) in the number line.

point after 2 is $2\frac{1}{9}$

point after $2\frac{1}{9}$ is $2\frac{2}{9}$

point after $2\frac{2}{9}$ is $2\frac{3}{9}=2\frac{1}{3}$

So, move 3 points after 2 in the number line is $2\frac{1}{9}$ .

The number line is attached below.
