Ответ:
The answer is each piece will weigh 1/8 of a pound.
Step-by-step explanation:
If she has 3/8 pounds of chocolate and cuts it into 3 pieces we will divide the total amount (or in this case weight) of the chocolate by 3 in order to get our answer. By taking 3/8 and splitting it into 3 equal pieces we are left with 3 pieces each weighing 1/8 of a pound. You can verify this is correct by multiplying 1/8 by 3 to get 3/8
Ответ:
Substitute x for the number 3 in the first equation.
f(x)=2(3)+1, then solve to get x=7
Substitute 7 for x in the second equation
g(x)=(3(7)-1)/2
g=(21-1)/2
g=(20)/2
g=10
