4/5 = x/9
Please solve this equation in decimal form.

x=7.2

Step-by-step explanation:

Cross multiply

4/5=x/9

5*x=4*9

5x=36

Divide by 5 on both dies

x=7.2

OR

Multiply both sides by 9

4/5=x/9

9*4/5=x/9*9

7.2=x

Hope this helps! :)

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
