7(10)^n=700

/7           /7

10^n=100

now we have to think 10 to what power is 100

Jlenok [28]

Answer:

He have left <u>1250 milliliters</u> of sport drink.

Step-by-step explanation:

Given:

Eduardo bought 2 litre sports drink for soccer practice during practice.

Eduardo drank 250 milliliters of sport drink then he drank another 1/2 liter.

Now, to find the milliliter of sport drink he have left.

Eduardo bought sports drink = 2 litre.

Now, to convert litre into milliliter by using conversion factor:

1 litre = 1000 milliliter.

2 liters = 2 × 1000 milliliters.

2 liters = 2000 milliliters.

<u><em>Thus, Eduardo bought 2000 milliliters sport drink.</em></u>

<u><em>As, Eduardo drank 250 milliliters of sport drink.</em></u>

So, to get the sport drink left after he drank we subtract 250 milliliters from 2000 milliliters:

2000-250\\\\=1750\ milliliters.

<u><em>Thus, 1750 milliliters sport drink left.</em></u>

Now, to get the sport drink left after he drank \frac{1}{2} \ liter we subtract \frac{1}{2} \ liter from 1750 milliliters:

\frac{1}{2} \ liter =500\ milliliters.

So,

1750-500\\\\=1250\ milliliter.

Therefore, he have left 1250 milliliters of sport drink.

Do you think any ordered pairs are solutions to BOTH y=x+5 and y=-2x-1? Explain.
Rina8888 [55]

Answer:

ordered pair(-2 , 3) is the solution

Step-by-step explanation:

y=x+5

y=-2x-1

x+5 = -2x-1    substitution

x+5+2x-5 = -2x-1+2x-5

3x = -6

x = -2

y = -2+5 = 3

ordered pair(-2 , 3) is the solution
