Simplify: 18q2−45q+25/9q2−25.

Svet_ta [14]

Answer:

$\frac{(6q-5)}{(3q+5)}$

Step-by-step explanation:

Given: $\frac{18q^{2}-45q+25 }{9q^{2}-25 }$

Factorizing the numerator and the denominator, we have:

18 $q^{2}$ - 45q + 25 = 18 $q^{2}$ - 30q - 15q + 25

= (3q - 5)(6q - 5)

and

9 $q^{2}$ - 25 = (3q - 5)(3q + 5)

So that,

$\frac{18q^{2}-45q+25 }{9q^{2}-25 }$ = $\frac{(3q-5)(6q-5)}{(3q-5)(3q+5)}$

= $\frac{(6q-5)}{(3q+5)}$

Therefore,

$\frac{18q^{2}-45q+25 }{9q^{2}-25 }$ = $\frac{(6q-5)}{(3q+5)}$

Explain your answer !! <br> Have a nice day <br><br> Will give braisnlt

Answer:

The equations are:

$4H + 3P = 13.75$

$2H + 5P = 11.25$

$Hotdog = 2.50$

$Pretzel = 1.25$

Step-by-step explanation:

Let:

$H = hot\ dog$

$P =Pretzel$

For Tina:

$4H + 3P = 13.75$

For Doug:

$2H + 5P = 11.25$

Solving for the price of both items:

We have:

$4H + 3P = 13.75$ --- (1)

$2H + 5P = 11.25$ --- (2)

Multiply (2) by 2

2 * ( $2H + 5P = 11.25$ )

-------------------

$4H + 10P = 22.50$ --- (3)

Subtract (3) from (1)

$4H + 3P = 13.75$

$4H + 10P = 22.50$

----------------------

$4H - 4H + 3P - 10P = 13.75 - 22.50$

$3P - 10P = 13.75 - 22.50$

$-7P = -8.75$

Solve for P

$P = \frac{-8.75}{-7}$

$P = 1.25$

Substitute 1.25 for P in (2)

$2H + 5P = 11.25$

$2H + 5 * 1.25 = 11.25$

$2H + 6.25 = 11.25$

Collect Like Terms

$2H = 11.25-6.25$

$2H = 5$

Solve for H

$H = \frac{5}{2}$

$H = 2.50$

What is the distance between (-5, 3) and (7, 3)?

Rama09 [41]

Answer:

12 units

Step-by-step explanation:

We would need to ignore the 3 first of all. We know that 3 is located at the same place. We then need to see 7 and -5. The distance from zero of each numbers matter, not the ammount. So (-5) is 5 from zero. (7) is 7 from zero. 5 + 7 = 12 units

If 1/x + 1/3х = 5, what is the value of 3x/4

marusya05 [52]

Answer:

Step-by-step explanation:

$\frac{1}{x}+\frac{1}{3x}=5\\\\\frac{1*3}{x*3}+\frac{1}{3x}=5\\\\\frac{3}{3x}+\frac{1}{3x}=5\\\\\frac{4}{3x}=5\\\\4=5*3x\\\\4=15x\\\\\frac{4}{15}=x$

x = 4/15

$\frac{3}{4}x=\frac{3}{4}*\frac{4}{15}\\\\=\frac{1}{5}$
