G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
The train is traveling at 165 mph
495/3=165
825/5=165
1155/7=165
1485/9=165
D,A,B,C i think this is correct !
Rotation, Translation, and Reflection are the 3 rigid motions that preserve angle measure and side length.
A dilation only preserves angle measure.
Therefore, the answers are A, C, and D
