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:
9.5 feets
Step-by-step explanation:
Length of drawing = 8 4/9 inches
Scale : 1/3 inch in drawing = 3/8 actual length
Length of drawing / drawing scale
8 4/9 = 76/9 inches
Number of 1/3 inches in total length of drawing :
76/9 ÷ 1/3
76/9 * 3 / 1
(76*3) /(9*1) = 228 /9 = 9 3/9 = 9 1/3
9 1/3 * 3/8 foot
(228 / 9) * (3 /8)
(228/3) * (1/ 8)
228 / 24
= 9.5 feet
