o-na [289]

Answer: x1 = 0; x2 = 5/3; x3 = 1/3

x1 + 2x2 - x3 = 3 => 2x1 + 4x2 - 2x3 = 6

                                2x1 + x2 - 2x3 = 1

=> 4x2 - x2 = 5

⇔ 3x2 = 5

⇔ x2 = 5/3

with x2 = 5/3, we have: x1 - x3 = 3 - 10/3 = -1/3

                                        3x1 - 5x3 = 5 - 4.5/3 = -5/3

=> x1 = 0

    x3 = 1/3

Since he bought a few of each length. The only combination that works is when he bought 5 of the 4 ft long board so 4×5=20. Than he bought 3 of the 5ft boards 3×5=15. 20+15=35 ft worth of boards.

X + y = 3 <br>-2x + 4y = 6
Finger [1]
I'm assuming this is a system of equations you want solved so,

x = -y + 3

-2(-y+3)+4y = 6
2y - 6 + 4y = 6
6y = 12
y = 2

x + 2 = 3
x = -1

Maryam's rectangular bedroom is 9 feet by 12 feet. What is the diagonal distance from one corner to the opposite corner?
ra1l [238]
Create a right triangle with the the two legs being sides of 9 and 12...then use the Pythagorean theorem to solve

a^2 + b^2 = c^2 

9^2 + 12^2 = c^2
81 + 144 = c^2 
225 = c^2 

Square root both sides to get c = 15 feet.
