Answer:
5.66 inches
Step-by-step explanation:
In this case I know the ratio or that 1 inch equals 12 miles, so 1 times 12. I need to find out how many inches represents 68 miles, so 12 times what number equals 68? I would divide 68 divided by 12 and I get 5.66 that terminates, the teacher should accept 5.66 inches or 5 and 2/3.
Answer:
X = -1/2 or 1/2
Step-by-step explanation:
When the square root of a number is found, this usually results in 2 solutions which may be equal in size but opposite in signs.
As such,
X^2=1 to find x find the root of both sides
X = √1
X = -1 or 1
Going by this
4x^2=1
Divide both sides by 4
X^2=1 /4
taking the square root of both sides
X = √1/4
The root of 1 is -1 or 1 while that of 4 is -2 or 2 hence,
X = -1/2 or 1/2
