What is the answer 8/5-1/6= ive been stuck on this question forever

Leviafan [203]

Answer:

1 13/30

Step-by-step explanation:

First you want to make the denominators the same. You do this by multiplying them. However, whatever you do you to the denominator, you must also do to the numerator:

$\frac{8x6}{5x6}$ - $\frac{1x5}{6x5}$ = $\frac{48}{30}$ - $\frac{5}{30}$ = $\frac{43}{30}$

Now reduce to simplest terms:

$\frac{43}{30}$ =1 $\frac{13}{30}$

Distance Formula: $\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify

Point (-1, -3.75)

Point (-1, 4.5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-1--1)^2+(4.5--3.75)^2}$
[√Radical] (Parenthesis) Subtract: $\displaystyle d = \sqrt{(0)^2+(8.25)^2}$
[√Radical] Evaluate exponents: $\displaystyle d = \sqrt{0+68.0625}$
[√Radical] Add: $\displaystyle d = \sqrt{68.0625}$
[√Radical] Evaluate: $\displaystyle d = 8.25$
