x = -1
Step-by-step explanation:
8 = 2^(x + 4)
Rewriting 8 as 2^3
2^3 = 2^(x + 4)
Since the bases are the same, the exponents must be the same
3 = x+4
Subtract 4 from each side
3-4 =x+4-4
-1 =x

Answer:
0.4 ounces
Step-by-step explanation:
In a day
Miguel is to feed Chester ,
Chester can eat 3/4 of an ounce for each pound of body weight.
Chester weighs 6.8 pounds
Hence:
1 pound = 3/4 ounce
6.8 pounds = x ounces
Cross Multiply
x = 6.8 × (3/4) ounces
x = 5.1 ounces
Chester is to be fed 5.1 ounces of food each day.
The amount of food left after 1 day
= 5.5 ounces - 5.1 ounces
= 0.4 ounces
Hence, 0.4 ounces of food is left after 1 day
