Now 4.5 * 4.5 = 20.25 so:
The estimate for the square root is 4.5.
Answer:
Any number less than 5/6 would work
Examples: 2/3, 1/2, 0, -1, -4, -100
The answer of your question is 20 gallons of gasoline. It just a simple division you just have to divide $25 which is the given money to buy an exact amount of gallon by $1.25 which is the price of each gallon. So you would come up to an answer of 20 gallons.
Solve by elimination
multiply top by -1
-2x + y = -4
x - y = -2
-x = -6..............so x = 6
2(6) - y = 4
12-y = 4
-8 = -y
so y = 8
(-6,8)
Y = -3x + 13
