Before you will sum up the following equation, first you must multiply the first equation by two and came up with 16x+14y=78 and then add it to the second equation which is 4x-14y=-68 and the remaining variable is 20x=10 then get the value of X and the value is 1/2 or 0.5. I hope you are satisfied with my answer
Answer:
Step-by-step explanation:
The right option es a)

Step-by-step explanation:
Volume = Length x Width x Height
V= 7.5 ft x 4.2 ft x w fr
The width is 2 as listed.
V= 7.5ft x 4.2ft x 2ft
V=63
3t = 5t - 8
-2t = -8
t = 4
Now put that into -4t + 5:
-4t + 5
-4(4) + 5
-16 + 5
-11
