Answer:
12 feet
Step-by-step explanation:
If we use a rectangle. there would be 4 sides the length we can represent as x and the width would result as 3x. If we use the perimeter formula, we would get 8x. 8x would equal 96, the perimeter.
8x= 96
x= 12
The length would be 12
Hope this helped!! :D
Okay so
area of picture= 192cm
area of frame= 40×24=960
960÷ 192= 5
Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24
The dimensions of the picture are then 8cm × 24 cm.
The solution to the given system of equation is (25/7, 6/7)
<h3>System of equation</h3>
Given the system of equation expressed as:
x= - 4y+7 ........... 1
-2y+3x=9 ...........2
Substitute the equation 1 into 2 into have:
-2y + 3(-4y+7) = 9
-2y + 3(-4y) + 3(7) = 9
-2y - 12y + 21 = 9
Collect the like terms
-14y = 9- 21
-14y = -12
y = 6/7
Substitute y = 6/7 into equation 1;
x =-4y + 7
x = -4(6/7) + 7
x= -24/7 + 7
x = -24+49/7
x = 25/7
Hence the solution to the given system of equation is (25/7, 6/7)
