I dont know the answer havent done math in a long time guys so i dont know
294 miles per 14 gallons = 21 miles per 1 gallon
So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:

Next, add the two equations together to get
. From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:

<u>In short, the solution is (2,-5), or A.</u>
Answer:
7/10
Step-by-step explanation:
In 0.7 we will change the decimal to fraction. First we will write the decimal without the decimal point as the numerator. Now in the denominator, write 1 followed by one zeros as there are 1 digit in the decimal part of the decimal number. Therefore, we observe that 0.7 (decimal) is converted to 7/10 (fraction).
Answer:
1.4000
2.5.551
3.6.8
4.10.00
5.4
Step-by-step explanation:
1 4066 as an example start from the end a 5 or more it turns to a zero and the one next to it
so in this case we now have 4100 but since it isn't 5 or more we make it a zero and move on so now we have 4000
sorry if I am wrong I am also an idiot so hopefully this helps for the future :)
