Answer is <em><u>3</u></em><em><u> </u></em><em><u>m/</u></em><em><u>s.</u></em>
<h3>Step-by-step explanation:-</h3>
The ostrich ran at a constant velocity, so it's velocity was :
It is said that the bird ran for 160 seconds and it made it half-way to its nest, so the distance was :
And the velocity is :-
Therefore, the ostrich ran at a velocity of <em><u>3 m/</u><u>s</u> .</em>

List the numbers
31,34,34,35,37,38,38,39
Mark out one from each side till you get 37 and 35 average them to get your answer
Step-by-step explanation:
AB = CD
3x + 10 = 5x
2x = 10
x = 10/2
x = 5 ans
AB = CD = 25 ans
1 Subtract <span><span>yy</span>y</span> from both sides
<span><span><span>43−y=<span>x3</span>−5</span>43-y=\frac{x}{3}-5</span><span>43−y=<span><span>3</span><span>x</span><span></span></span>−5</span></span>
2 Add <span><span>55</span>5</span> to both sides
<span><span><span>43−y+5=<span>x3</span></span>43-y+5=\frac{x}{3}</span><span>43−y+5=<span><span>3</span><span>x</span><span></span></span></span></span>
3 Simplify <span><span><span>43−y+5</span>43-y+5</span><span>43−y+5</span></span> to <span><span><span>48−y</span>48-y</span><span>48−y</span></span>
<span><span><span>48−y=<span>x3</span></span>48-y=\frac{x}{3}</span><span>48−y=<span><span>3</span><span>x</span><span></span></span></span></span>
4 Multiply both sides by <span><span>33</span>3</span>
<span><span><span>(48−y)×3=x</span>(48-y)\times 3=x</span><span>(48−y)×3=x</span></span>
5 Regroup terms
<span><span><span>3(48−y)=x</span>3(48-y)=x</span><span>3(48−y)=x</span></span>
6 Switch sides
<span><span><span>x=3(48−y)</span>x=3(48-y)</span><span>x=3(48−y<span>)</span></span></span>
The given statement written in symbolic language is x = 3y + 4 and x + y = 72 where "x" is the cost of one book and "y" is the cost of another book
<em><u>Solution:</u></em>
Given that Bruce bought two books
One book costs $ 4.00 more than three times the other
Let the two books be denoted as Book A and book B
Let "x" be the cost of book A
Let "y" be the cost of Book B
From given,
One book costs $ 4.00 more than three times the other
Let Cost of book A = $ 4.00 more than three times the other book B
x = 4 + 3 times cost of Book B
x = 4 + 3y
x = 3y + 4 --- (i)
Also given that Together, the two books cost him $72
cost of book A + cost of Book B = 72
x + y = 72 ------- (ii)
Therefore the given statement written in symbolic language is:
x = 3y + 4 and x + y = 72
