Re-solve please.<br><br> 2 5/6 + (-1 4/12) =

elena-s [515]

Answer:

1.5 as decimal, 1 1/2 as a fraction

Step-by-step explanation:

1. convert 2 5/6 & (-1 4/12) to a improper fraction.

17/6 and -16/12

2. multiply 17/6 by 2 to match -16/12's denominator

17/6 * 2 = 34/12

We now have

34/12 + -16/12

A positive number plus a negative number is the same thing as subtraction so we remove the negative sign and replace the plus with a minus sign.

We have:

$\frac{34}{12}-\frac{16}{12}$

Now solve. 34-16 = 18

our answer is 18/12

Slope= $\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$

(3,5) and (1,9)
x1=3
y1=5
x2=1
y2=9

Slope= $\frac{ y_{2}- y_{1} }{ x_{2} - x_{1} }$
Slope= $\frac{ 9- 5 }{ 1 - 3}$
Slope= $\frac{4}{ -2}$
Slope= $-\frac{4}{2} or -2$

Answer:Slope=-2
