Answer:
0.500
Step-by-step explanation:
First equate 4x+7y=3x,
we get, x+7y=0 ---->equ 1
Now equate 3x=y-2, we get 3x-y=-2 ----->equ2
solve equ 1,2,
We get x= -7/11, y=1/11
Answer:
=

Step-by-step explanation:
Given:
Length of butcher paper,(diameter of three congruent circle) = 21 inches
Means, diameter of a circle =
= 7 inches
Questioned asked:
Area of one circle = ?
Solution:
Radius of a circle ,r = half of of one circle's diameter
r = 
= 
Area of circle = 


=

Therefore, Area of one circle ==

A ) Length = 5 - 2 x
Width = 3 - 2 x
The area of the bottom:
A = L x W = ( 5 - 2 x ) ( 3 - 2 x ) = 15 - 10 x - 6 x + 4 x² =
= 4 x² - 16 x + 15
b ) 4 x² - 16 x + 15 = 10
4 x² - 16 x + 5 = 0
x = (16 - √(256 - 80))/ 8 = ( 16 - 13.266 ) / 2
x = 0.34 in
