Solve for z.
z/12 = 4/5

z=9.6

Step-by-step explanation:

To solve, we need to isolate z

z/12=4/5

Cross multiply

5*z=12*4

5z=48

Divide by 5 on both sides

z=9.6

Another way to approach this is to multiply both sides by 12, to"reverse"the division being done to z

z/12=4/5

12(z/12)=(4/5)12

z=9.6

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
