The number are <span>(−5.4) and (+8.2).
Sum of these two numbers are = </span><span>(−5.4) + (+8.2)
= -5.4 + 8.2
= 2.8
Now we are going to add this to the opposite number of </span><span>(−2 3/4 ).
</span><span>(−2 3/4 ) = -11/4 = -2.75
now opposite number of -2.75 is 2.75
Thus, 
2.8 + (2.75)
= 2.8 + 2.75
= 5.55</span>

vladimir2022 [97]

Answer:

580ml

Step-by-step explanation:

Let The quantity of water drank by Carol be x

Now given that Keela drank twice as much water as Carol which means the quantity of water drank by Keela is 2x

Also given that Xavier drank 100 mL more water than Keela which means the quantity of water drank by Xavier is 2x+100

Total water consumed by all the three is 3 litres=3000 ml

Total water drank = Water drank by Keela + Water drank by Xavier +Water drank by carol

3000=x+2x+2x+100

5x=2900

x=580ml

Carol drank 580ml of water.

Convert 7.7km into miles if 1.6 km = 1 mile
Lemur [1.5K]
This is a simple equation.  

The equation is y = 1.6x  with y being the miles and x being the kilometers.

Lets plug the kilometers in.

Y=1.6(7.7)

1.6 *  7.7 = 12.32

12.32 miles is  equal to 7.7 kilometers

HOWEVER

There are about .6 miles in a kilometer, so if you typed this wrong I don't know.  

It is still the same concept.

Y = .6x

Y = .6(7.7)

.6 * 7.7 =  4.8

In this case there are 4.8 miles in 7.7 kilometers
