Answer:

x=2

Step-by-step explanation:

ok so this is just a substitution problem.

we need to get the variable (x) by itself on one side.

4x+8=16. so, lets remove 8 from the left side, and whatever we do to one side also has to happen to the other.

4x+8=16

    -8  -8

4x=8. So now, we want to get 4 separate from x, and the only thing we can do is divide.

4x=8

/4  /4

x=2. there you have it, x is 2.

Answer: Actually, you must use the Pythagorean Theorem!

a squared plus b squared equals c squared. So if you substitute in the values, a is 2 units and b is three units. 2 squared is 4 and 3 squared is 9.

4 + 9 = 13 so the answer is the square root of 13. (√13)

Cerrena [4.2K]

Answer:

113/24

Step-by-step explanation:

Simplify the following:

(14 + 1/8)/3

Put 14 + 1/8 over the common denominator 8. 14 + 1/8 = (8×14)/8 + 1/8:

((8×14)/8 + 1/8)/3

8×14 = 112:

(112/8 + 1/8)/3

112/8 + 1/8 = (112 + 1)/8:

((112 + 1)/8)/3

112 + 1 = 113:

(113/8)/3

113/8×1/3 = 113/(8×3):

113/(8×3)

8×3 = 24:

Answer: 113/24
