Answer:

If what I think youre saying is correct, then it should be 1/9

Step-by-step explanation:

4/15 + (-7/45)

Multiply both numerator and denominator of 4/15 by 3 so that the denominator becomes 45 to match the other fraction.

12/45 + (-7/45)

As the fraction on the right side is negative, it is taken away from the left fraction, hence:

(12 - 7)/45

Therefore, with simple subtraction,

5/45

Simplify to 1/9

kupik [55]

Answer:

The answer is "She cut a total of 42 pieces of pie".

Step-by-step explanation:

Given :

Total pie= $5 \frac{1}{4}$

cut pie = $\frac{1}{8}$

The number of pieces of the pie she has=?

Solve the mixed fraction value:

$\to 5 \frac{1}{4}= \frac{21}{4}$

If she cuts the pieces into the entire pie, that is = $\frac{1}{8}$

So, the equation is:

$\to \frac{21}{4} = \frac{1}{8} \times x$

$\to x= \frac{21 \times 8}{4}\\\\ \to x= 21 \times 2\\\\ \to x=42$

Write an equation of the line below

Ratling [72]

Answer:

y = 3/5 + 4

Step-by-step explanation:

Given Coordiantes:

(0,4) - Y-intercept

(5,7) - Coordinates

To make an equation, first find the slope.

$m=\frac{rise}{run} =\frac{y}{x}$

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

$m=\frac{7-4}{5-0}$

$m=\frac{3}{5}$

In decimals:

$m = 0.6$

Now convert to point slope.

$y-y_{1} =m(x-x_{1} )$

$y-4=\frac{3}{5} (x-0)$

In decimals:

$y-4=0.6(x-0)$

Now convert to slope-intercept form.

Find the Equation of the Line:

$y=mx+b$

by solving for y using the Point Slope Equation.

y = 3/5 + 4
