N - 1/8 = 3/8 I am no smort and i forgot to study for a test =|

sdas [7]

Answer:

$\boxed{\sf{n=\dfrac{1}{2}=0.5 }}$

Step-by-step explanation:

Isolate the term of n from one side of the equation.

First, add by 1/8 from both sides.

n-1/8+1/8=3/8+1/8

Solve.

Add the numbers from left to right.

3/8+1/8=4/8

Common factor of 4.

4/4=1

8/4=2

Rewrite as a fraction.

=1/2

n=1/2

Divide is another option.

1/2=0.5

n=1/2=0.5

Therefore, the final answer is n=1/2=0.5.

I hope this helps you! Let me know if my answer is wrong or not.

Evaluate 4(3h + 7) ————— for h = -2 4 +h

Juliette [100K]

If i understood the question right, you're trying to find the value when h = -2. If that's true so here is how it's done:

$4(3h + 7)\\4(3(-2) + 7)\\4(-6+7)\\4(1)\\=4$

the 5 and x is being multiplied the opposite of multiplication is dividing

so 95/5= 19
