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 ....

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

Identify BR rounded to the nearest tenth. HELP PLEASE!!
ahrayia [7]

Answer:

<h2>BR ≈ 49.0</h2>

Step-by-step explanation:

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have

adjacent=42\\hypotenuse=BR\\\alpha=31^o

\cos31^o\approx0.8572

Substitute:

\dfrac{42}{BR}=0.8572

\dfrac{42}{BR}=\dfrac{8,572}{10,000}          <em>cross multiply</em>

8,572BR=420,000                <em>divide both sides by 8,572</em>

BR=\dfrac{420,000}{8,572}

BR\approx49.0
