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.
Answer:B
Step-by-step explanation:
4E and LA are right angles; therefore, these angles are congruent since all right
angles are congruent. Is - 15 over 5 and 12 over 4shows the corresponding sides are proportional;
therefore, ABC ~ AEDC by the SSS Similarity Postulate.
6(8-2y)=4y
48-12y=4y
48=16y
y= 48/16
y=3
hope helped
