Answer:

okay so im not sure which is being round so i'll do both

if you are going to round the miles and gallons:

278.2 to 278 because the decimal is below 0.5

19.6 to 20 because the decimal is above 0.5

278/20 = 13.9 which you would round to 14 because the decimal is above 0.5

if you are only going to round the answer:

278.2/19.6 = 14.193877551 which you would round to 14 because the decimal is below 0.5

so regardless of what you do, <u> your answer will be 14</u>

Solve 3x+2y=4 4x+3y=7 algebraically
Leona [35]
Step 1. Multiply first equation with -3 and the second one with 2. You'll get:
\left \{ {{-9x-6y=-12} \atop {8x+6y=14}} \right.

Step 2. Add both equations together. You'll get:
-x=2, which gives x = -2

Step 3. Replace x = -2 in the first equation and calculate y.
3(-2)+2y=4\\&#10;y=\frac{4+6}{2}=5

The solution is: x=-2, y=5
