Answer:
8
Step-by-step explanation:
Compatible numbers are defined as the numbers which are very close to the numbers that they are replacing that divides evenly into each other.
In the context, we have to estimate the quotient using the compatible numbers in order to estimate 245 divided by 3.
So, estimating 245 as 240 and 3 as 30.
Here, 240 is very close to 245 and 30 is close to 3. So the quotient is the result when we divide 240 by 30 and it divides evenly into 240.
We first divide the non zero parts of each number i.e. 24 by 3 to get the first part of the estimate.
Then we add on the zero if there were left in the problem to get your estimate.
Therefore,
240 / 30 = 8
So here, the quotient is estimated as 8.
Answer:
I'm pretty sure it's -3/2
Answer:
1/8 cm = 0.125 cm = 1.25 mm
6 * (1.25 mm)^2 = 9.375 mm^2
X^2-X-6=(X-3)(X+2)
(X+2)/(x+2)=1
Which just leaves (x-3)
X=3
