Answer:
-3 \frac{3}{7} 

Explanation:
\frac{-24}{7} = -3 \frac{3}{7} 
So first make the improper fraction into a mixed number by taking out all the whole numbers from the numerator (3) and making sure the proper sign is in front of the answer (- 3) your remainder is the original numerator minus the product of the answer times the denominator: 24 - (3 • 7) = 24 - 21 = 3. Rewrite the mixed number.

natulia [17]

Answer:

Option D doesn't make any sense.

Step-by-step explanation:

D) 7 hours of sleep correspond to an age of 19 years.

That is wrong.

If we use the expression provided

hours = 8 + 0.5*(18 -age)

hours = 8 + 0.5*(18 -19)

hours = 8 + 0.5*(-1)

hours = 7.5

Tommy has three times as many video games as Griffin. Fletcher has eight less than Tommy. The total number of video games is les
zimovet [89]

Answer:

x = 6.86

Number of video games Fletcher has = 12.58

Step-by-step explanation:

Let

Number of video games Griffin has = x

Number of video games Tommy has = 3x

Number of video games Fletcher has = 3x - 8

Total number of video games is > 40

Griffin + Tommy + Fletcher > 40

x + 3x + (3x - 8) > 40

4x + 3x - 8 > 40

7x > 40 + 8

7x > 48

x > 48 / 7

x > 6.86

Number of video games Fletcher has = 3x - 8

= 3(6.86) - 8

= 20.58 - 8

= 12.58
