Answer:
Step-by-step explanation:
When multiplying fractions, you multiply the numerators together and denominators together. This means that the problem above can be rewritten as, 
. Then, multiply this out to get 
. However, this fraction can be simplified by dividing the numerator and denominator by 2. This gives the final answer, .
Answer:
0.83
Step-by-step explanation:
All fractions are division problems, so you just need to divied 5 by 6. You get 0.83333333 but you can round it to 0.83.
There are 3 × 4 = 12 pieces total
14 × 1/4 = 3.5 pizzas needed
not enough, you need two more slices
One way to approach this is to find (g o f)(x) first and then to replace x by -7:
g( f(x) ) = (x^2+6) + 8/(x^2+6)
Now replace x with -7. We get: ( g o f )(-7) = 49+6+8 / (49+6), or
= 55 + 8 / 55, or 55 8/55 (ans.)
