D = t*s
distance = time * speed
d = t*30
Answer:
A
Step-by-step explanation:
If we distribute the 3 to the equation in the parenthesis, we end up with this
12h + 6k
Now, let's do the same thing for the other two equations
3(2k + 4h) = 6k + 12h
You can rearrange this equation to look like 12h+ 6k, making it the exact same as 3(4h + 2k).
So A is equivalent
How about B?
3(4h + 2h) = 12h + 6h = 18h
18h does not equal 12h + 6k, so B is not equivalent
5= (6+4)x
5= 10x
5= 10x then divide by 10 to get the variable by itself
__ ___
10 10
.5 = x you can use .5 or 1/2
hope this helps!

Percent of increase. When it is more than the original amount, it is an increase. When it is less, it is a percent of decrease.
