x = 8-(-2.25) = 8+2.25 = 10.25

y = 6-4.2-(-4.9)=6-4.2+4.9=6+0.7=6.7

<span>x-y = 10.25.-6.7= \frac{1025}{100} - \frac{670}{100} = \frac{1025-670}{100} = \frac{355}{100} =3.55</span>

x=8-(-2.25)
x=8+2.5
 x=10.5


y=6-4.2-(-4.9)
y=1.8+4.9
y=6.7

x-y=10.5-6.7=3.8
The  answer is: 3.8

The compound inequality 8.00 ≤ x &lt; 9.50 represents all values, x, for which college students are paid hourly as teacher assis
Orlov [11]

Answer: x≥ 8.00 and x < 9.50 is the correct option.

Step-by-step explanation:

Since, given expression 8.00 ≤ x < 9.50

Where x is the value for which college students are paid hourly as teacher assistants.

so, x is greater than or equal to 8.00

Therefore, x\geq 8.00  

And, x is less than 9.50

Therefore,  x < 9.50

On combining both expression we get,  x\geq 8.00 and x < 9.50.

Thus, Third Option is correct.
