5. Use the rules for long division to divide 262 by 9. A. 29r1 B. 28 C. 30 D. 29

vfiekz [6]

Since $270=262+8$ , and $\dfrac{270}9=30$ , we have

$\dfrac{270}9=\dfrac{262}9+\dfrac89$
$\implies30-\dfrac89=\dfrac{262}9$
$\implies29+\dfrac19=\dfrac{262}9$

so the answer is A.

Find the slope of the line passing through (3, 7) and (6, 11). Note: Use the y-y/x-x formula!

lana [24]

Answer:

Slope of the line $m = \frac{4}{3}$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given points are ( 3,7) and (6,11)

Slope of the line

$m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

$m = \frac{11-7}{6-3}$

$m = \frac{4}{3}$

Slope of the line $m = \frac{4}{3}$

The sum of the reciprocals of two consecutive even integers is 7/24. Write an equation that can be used to find the two integers

sergejj [24]

Assume the first even integer is x.
The next even integer will be 2 digits after this digit. So the next even integer will be x+2.

The reciprocals of these two even integers can be written as $\frac{1}{x}$ and $\frac{1}{x+2}$ respectively.

The sum of their reciprocals is 7/24. So we can set up the equation as:

$\frac{1}{x}+ \frac{1}{x+2}= \frac{7}{24}$

Taking LCM on left hand side:

$\frac{x+2+x}{x(x+2)}= \frac{7}{24} \\ \\ 
 \frac{2x+2}{ x^{2} +2x}= \frac{7}{24}$

Cross Multiplying the denominators:

$24(2x+2)=7({ x^{2} +2x}) \\ \\ 
48x+48=7 x^{2} +14x \\ \\ 
7 x^{2} +14x-48x-48=0 \\ \\ 
7 x^{2} -34x-48=0 \\ \\ 

$

Using the quadratic formula to solve the above equation:
$7 x^{2} -34x-48=0 \\ \\ 
x= \frac{34+- \sqrt{1156+1344} }{14} \\ \\ 
x= \frac{34+- \sqrt{2500} }{14} \\ \\ 
x=\frac{34+-50 }{14} \\ \\ 
x=6 \\ x=- \frac{8}{7} 
$

Since, the value of x can only be an integer, we discard the fractional value and keep x=6

So the first even integer is 6 and the next even integer is 8. The sum of reciprocals of 6 and 8 is 7/24
