Answer:
A.
Step-by-step explanation:
12.5/10=1.25.
12.5/8=1.56
12.5/12=1.04
12.5/6=2.08
it's important to know what 1/2 is, 1/3 is, 1/4 is and 1/5 it's also important to know things like 2/2, 2/3, 3/3, 2/4, 3/4, 4/4, 2/5, 3/5, 4/5, and 5/5. You don't need this until 8th grade though. But get on it if you can. Ask your parents or teacher.
I think the answer might be 45
Answer:
b
Step-by-step explanation:
This is an easy one!
Three times a number = 128
3x = 128
x = 128/3
x = 42.66666.
Hope this helps!
Funciton form is f(x)=something
basicallly know that f(x) is the output or y
just solve for y
-3x-6y=0
add 3x to both sides
-6y=3x
divide both sides by -6
y=-1/2x
f(x)=(-1/2)x
