13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2
y = -8
Answer:
0.422 L
Step-by-step explanation:
A little-used fact is that a <em>liter</em> is a <em>cubic decimeter</em>. The dimensions of your cube are ...
edge length = 75 mm = 75/1000 m
Since a decimeter is 1/10 of a meter, we want the denominator to be 10. Moving the numerator and denominator decimal points 2 places to the left, we get ...
edge length = 0.75/10 m = 0.75 dm
Then the volume of the cube is ...
V = (0.75 dm)^3 = 0.422 dm^3 = 0.422 L
Answer:
1/3
Step-by-step explanation:
F = 36
G = 4
We know that The area is multiplied by the scale factor squared
F * (SF) ^2 = G
36 (SF) ^2 = 4
Divide each side by 36
36/36 (SF) ^2 = 4/36
(SF) ^2 = 1/9
Take the square root of each side
sqrt((SF)^2) = sqrt(1/9)
SF = 1/3
The scale factor is 1/3
