A²+b²=c²
12²+35²=c²
144+1225= c²
c²=1369
c=√1369
c=37
The aim here is to get all of the x's onto one side and the numbers onto the other side:
We can start by subtracting x from each side
2x+11=1
We can then subtract 11 from both sides
2x=-10
Finally, we can divide both sides by 2 leaving us with:
x = -5
Combine like terms.
3x + 4x -5 -2
7x - 7
Answer:
Gretchen because a 1/5 is bigger than 1/8 so 3/5 is bigger than 3/8
Since it could drive 49 miles on 1 gallon, and this is also it's gas mileage, (because 490/10=49) it could drive 45 times more on 45 gallons than on one. So, we multiply 45 by 49 to get 2209 gallons on 45 gallons of gas.
