The scale factor would be 0.2 because you have to divide the new stamp by the original so it would be 1.9/9.5=0.2 and same with 1.4/7=0.2

What is the area of this figure?
aleksley [76]
Find:  1) the area of a circle of diamter 5 feet and radius 5/2 feet.
           2) the area of a triangle with height 4 ft and base 6 ft.

Add these 2 results together:  pi*(5/2)^2 + (1/2)(6)(4)   ft

The trick here is to recognize basic shapes, find their areas separately and add the results.

Tell wether the ordered pair (5,-3) is a solution of the system -3x+2y=-21;-x-y=-2
Viefleur [7K]

Answer:

(5,-3) is a solution of -x-y=-2

Step-by-step explanation:

You just plug in the numbers in the equation

x=5 y=-3

-5(5)+2(-3)=-25-6 which doesn't equal -21

-5-(-3)=-5+3=-2

How do I solve this? Please show steps clearly so i can understand, thank you
Lesechka [4]

Answer:

The value of x=8.

Step-by-step explanation:

Given:

\frac{x+3}{x}-\frac{x+1}{x+4}=\frac{5}{x}

We need to solve this equation.

Solution:

First combining equation having same denominators we get;

\frac{x+3}{x}-\frac{5}{x}=\frac{x+1}{x+4}

Now denominators are common so we will solve the numerators we get;

\frac{x+3-5}{x}=\frac{x+1}{x+4}\\\\\frac{x-2}{x}=\frac{x+1}{x+4}

Now by cross multiplication we get;

(x-2)(x+4)=x(x+1)

Now Applying distributive property we get;

x^2+4x-2x-8=x^2+x\\\\x^2+2x-8=x^2+x

Now Combining the like terms we get;

x^2+2x-x^2-x=8\\\\x=8

Hence on solving we get the value of x=8.
