Solve for b B=??????

kozerog [31]

Answer:

$\frac{b-7}{b+1}=\frac{b-10}{b+4}$

$\left(b-7\right)\left(b+4\right)=\left(b+1\right)\left(b-10\right)$

$\left(b-7\right)\left(b+4\right)=b^2-3b-28$

$\left(b+1\right)\left(b-10\right)=b^2-9b-10$

$b^2-3b-28=b^2-9b-10$

$b^2-3b-28+28=b^2-9b-10+28$

$b^2-3b=b^2-9b+18$

$b^2-3b-\left(b^2-9b\right)=b^2-9b+18-\left(b^2-9b\right)$

$6b=18$

$\frac{6b}{6}=\frac{18}{6}$

$b=3$

A map using a scale of 1 inch:5 miles shows a section of land with an area of 3.2 inches what is the actual area of the section

Firlakuza [10]

Answer:

16 miles

Step-by-step explanation:

A scale drawing is a reduced form in terms of dimensions of an original image / building / object

the scale drawing is usually reduced at a constant dimension

scale of the drawing = original dimensions / dimensions of the scale drawing

Actual area = 3.2 x 5 = 16 miles

-2x-9y=-25 -4x-9y=-23

goldfiish [28.3K]

So to start this off you would add 9y to both sides of the equation and then you regroup it which gives you −2x=−25+9y and then you regroup the terms and get -2x=9y-25 and then you dived both sides by -2 and get x=9y-25/-2 then you simplify and so on

but at the end you should get x=-1 and y =3
