<span>length is 3 times the width = 3W
A = L * W
48 = 3W * W
48 = 3W^2
W^2 = 48/3
W^2 = 16
W^2 =4^2
W =4
answer: width is 4ft</span>
Answer:
we approach the issue by taking note of that a 2 x 2 matrix can either have 1 0r 2 pivot columns. If the matrix has no pivot columns then every entry in the matrix must be zero.
-> if our matrix has two pivot columns then :
-> if our matrix has one pivot column then we have a choice to make. If the first column is pivot column then:
->otherwise, if the pivot column is the second column then:
Answer:
1/5

Answer:
x = 7 and y = -2
Given:
x = 5y + 17 _____first equation
2x + 3y = 8 ____second equation
Steps:
2x + 3y = 8
<em>plug in x = 5y + 17 into second equation</em>
<em></em>
2(5y + 17)+3y = 8 [ open the brackets ]
10y + 34 + 3y = 8
10y + 3y = 8 - 34 [ collect and group terms ]
13y = -26 [ divide both sides by 13 ]
y = -2 [ final answer ]
solve for x:
x = 5y + 17
x = 5(-2) + 17
x = 7
