Which shows 21/12 as a mixed number in simplest form

a. 6 1/4
b. 6 1/2
c. 6 2/4
d. 6 3/4

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
