ASAP PLEASE HELP!! “Find the quotient”

elena-14-01-66 [18.8K]

Answer:

The quotient is $\frac{x(2x-3)}{7}$ answer (D)

Step-by-step explanation:

$\frac{2x-3}{x}$ ÷ $\frac{7}{x^{2} }$

In division with fractions we reverse the fraction after division sign and change division sign to multiplication sine

$\frac{2x-3}{x}$ × $\frac{x^{2} }{7}$

$\frac{2x-3}{1}$ × $\frac{x}{7}$

$\frac{x(2x-3)}{7}$

Find the coordinates of point z such that the ratio of fz to zd is 5;3

Vilka [71]

The point such that the coordinate is 5;3 is (14, 0)

<h3>Midpoint of coordinates using ratio</h3>

The formula for finding the midpoint of a line in the ratio m:n is expressed as:

M(x, y) = {(mx₁+nx₂)/2, (my₁+ny₂)/2,}

Given the coordinate of G and D on the line as G(5, 0) and D(1,0)

Since there is no y-axis, hence;

x = 5(5)+1(3)/2

x = 25+3/2

x = 28/2

x =14

Hence the point such that the ratio is 5;3 is (14, 0)

Select point B, and drag it. As you drag B, circle AB changes. Verify that you can make circle AB coincide with AC. Return B to

-BARSIC- [3]

Answer:

When AB coincides with AC, the boundary of EAF maps exactly onto the boundary of CAD, implying that EAF dilates into CAD. So, the boundaries of EAF and CAD are similar.

The proportional relationship may be stated in different forms, but should be equivalent to this equation:

radius of Ab/ radius of Ac= length of arc EF/ length of arc CD

Explanations will vary, but should be based on the similarity of EAF and CAD. The proportional relationship follows from the fact that corresponding pairs of lengths in two similar figures have the same ratio.

Step-by-step explanation:

This is the exact answer so make sure you change it up a little.
