We look for pairs of numbers in order to further simplify certain unsimplified square roots. For example, the square root of 20. From this, we pull out a 5 and two 2’s, Since there is a pair of 2’s, we carry one out, and since the 5 is not a pair, it stays inside of the radical. Therefore making it 2√5.
180/60=3
42/3 is 14
so 14 km per hour is your answer
They are in the ten thousandths and hundred thousandths place
It's A because 7.5 is the starting point but it's not included so that point is circled.
Answer:
First number x = -0.6
Second number y = 18.66
Step-by-step explanation:
Let the first number = x
and Second number = y
Sum of two numbers is 18. We can write it in mathematical expression as:

5 times the number subtracted from 4 over 7 of the second number is 14. We can write it in mathematical expression as:

So, solving the equations simultaneously we can find value of x and y
Let:

Finding value of x from equation 1 and put it in eq(2)

Put in equation 2

So, Value of y= 18.66
Now finding value of x, By putting value of y in eq(1)

So, First number x = -0.6
Second number y = 18.66
