Answer:
(x, y) = (4, -2)
Step-by-step explanation:
The coefficient of y in the second equation is double the coefficient of y in the first. We can subtract twice the first equation from the second to eliminate y.
(3x +4) -2(x +2y) = (4) -2(0)
x = 4 . . . . . . . . . simplify
Substituting into the first equation, we have ...
4 +2y = 0
2 +y = 0 . . . . . . divide by 2
y = -2 . . . . . . . . subtract 2
The solution is (x, y) = (4, -2).
7 1/4 + 5 3/5 = 12 17/20 You can't reduce it no more.
600 ft^2
Find the area of one face by multiply 10x10 which equals 100, then multiply that by the number of faces of a cube:6
100*6=600
The answer is 225
I got that by mulitplying .15 by 1500
The answer is none. There are no solutions
