What is the estimate answer and the exact answer of 17/10 ÷2 4/5

OLEGan [10]

Both 17/10 and 2 4/5 should be rounded up in preparation for this estimation.

17/10 is close to 2 and 2 4/5 is close to 3. Thus, your estimated answer should be
2/3, or approx. 0.6666....

Exact answer: divide 17/10 by 14/5. LCD is 10, so convert 14/5 to 28/10.

Now divide 17/10 by 28/10. Answer: 17/28 = approx. = 0.607 approx.

These two results are comparable: 0.6666.... and 0.6071 ....

Answer:

2^2 ( 1,2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12) = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44,48

3^2(1,2,3, 5) = 9, 18, 27, 45

5^2(1, 2) = 25, 50

6x-1 + 4X+21 = 50 solve for x

emmainna [20.7K]

Answer:

x=3

Explanation:

First what you do is move x to one side and the rest of the numbers to another while changing the sign from + to - or - to + like this
6x+4x= 1+-21+50

Then you do the equation on 1 side
6x+4x=30

And then the other but add them like x is not there
10x=30
Your final result should be
X=3
