Change each mixed number into an equal improper fraction a. 1 7/16, b. 11 5/9, c. 30 5/9, d. 10 10/13, e. 24 3/5, f. 129 1/2

elixir [45]

Answer:

a)

$\dfrac{23}{16}$

b)

$\dfrac{104}{9}$

c)

$\dfrac{275}{9}$

d)

$\dfrac{140}{13}$

e)

$\dfrac{103}{5}$

f)

$\dfrac{259}{2}$

Step-by-step explanation:

<em>" A fraction in which the numerator is greater than the denominator "</em>

We have to change each of the mixed fraction into improper fraction:

We know that the mixed fraction is converted into fraction as:

$a\frac{b}{c}=\dfrac{a\times c+b}{c}$

a)

$1\frac{7}{16}$ could be written as:

$=\dfrac{1\times 16+7}{16}\\\\=\dfrac{16+7}{16}\\\\=\dfrac{23}{16}$

b)

$11\frac{5}{9}$

$=\dfrac{11\times 9+5}{9}\\\\=\dfrac{99+5}{9}\\\\=\dfrac{104}{9}$

c)

$30\frac{5}{9}$

$\dfrac{30\times 9+5}{9}\\\\=\dfrac{270+5}{9}\\\\=\dfrac{275}{9}$

d)

$10\frac{10}{13}$

$\dfrac{10\times 13+10}{13}\\\\=\dfrac{130+10}{13}\\\\=\dfrac{140}{13}$

e)

$24\frac{3}{5}\\\\=\dfrac{24\times 5+3}{5}\\\\=\dfrac{100+3}{5}\\\\\dfrac{103}{5}$

f)

$129\frac{1}{2}\\\\\\=\dfrac{19\times 2+1}{2}\\\\=\dfrac{258+1}{2}\\\\=\dfrac{259}{2}$

The table represents a linear equation. Which equation correctly uses point (–2, –6) to write the equation of this line in point

sineoko [7]

Answer:

$y+6=m(x+2)$

where I would have to look at the table to know $m$ .

Step-by-step explanation:

Point-slope form of a line is

$y-y_1=m(x-x_1)$

where $m \text{ is the slope and } (x_1,y_1) \text{ is a point on that line}$

You are given $(x_1,y_1)=(-2,-6) \text{, but no value for }m$ .

So we know we are looking for an equation that looks like this:

$y-(-6)=m(x-(-2))$

If you simplify this looks like:

$y+6=m(x+2)$
