Step-by-step explanation:

elimination of x:

-6x +5y = 1

6x + 4y = -10

___________+

9y = -9

y = -9/9 = -1

elimination of y:

-24x +20y = 4

30x + 20y = -50

_____________-

-54x = 54

x = 54/-54 = -1

\huge{ \mathcal{  \underline{ Answer }\:  \:  ✓ }}

The given equations are :

\longrightarrow - 6x + 5y = 1

\longrightarrow6x + 4y =  - 10

let's add the equations

\longrightarrow\small{ - 6x + 5y +6x + 4y =  1  + ( - 10)}

\longrightarrow9y =  - 9

\longrightarrow y =  - 1

now, let's plug the value of y in first equation :

\longrightarrow - 6x + (5 \times  - 1) = 1

\longrightarrow - 6x  - 5 = 1

\longrightarrow - 6x = 6

\longrightarrow x =  - 1

A student had 500 milliliters of water in a water bottle. She drank 25% of the water before soccer practice. After practice, she drank 1/3 of the remaining water.

​How much water, in milliliters, does the student have left in the bottle?

Answer:

the amount of water the student have left in the bottle is 250 milliliters

Step-by-step explanation:

A student had 500 milliliters of water in a water bottle. She drank 25% of the water before soccer practice. After practice, she drank 1/3 of the remaining water.

​How much water, in milliliters, does the student have left in the bottle?

Before the soccer practice, she drank 25 % of the water

25% of the water = 25% of 500

                             = 25% × 500

                              =\frac{25}{100} ×  500

At the right hand-side of the equation, the two zeros will cancel-out the other two zeros, hence;

                                = 25 × 5

                                 =125

25% of the water = 125 milliliters

From the question, it was said that drank 25% of the water before soccer, this implies that she drank 125 milliliters from the water bottles.

If she drank 125 milliliters of  from a 500 milliliters water contain in the water bottle, then the amount of water left will be 500 ml - 125 ml = 375 ml

This implies that before the soccer practice she had 375 milliliters of water left in the water bottle.

After the practice, she drank 1/3 of the remaining water, which means after the practice she drank 1/3 of 375

1/3 of 375 = \frac{1}{3} × 375 = \frac{375}{3} = 125

After the practice she drank 125 milliliters of water from her 375 milliliters water.

The amount of water she have left after the practice will be;

375 milliliters - 125 milliliters = 250 milliliters

Therefore, the amount of water the student have left in the bottle is 250 milliliters
