What is the simplified form of 3/4x+3+21/8x^2-14x-15

creativ13 [48]

Solution:

We have been asked to find the simplified expression of

$3/4x+3+21/8x^2-14x-15=\frac{3}{4x+3} +\frac{21}{8x^2-14x-15}\\ \\ \text{We will have to make the denominator equal to add}\\ \\ \ 8x^2-14x-15=8x^2+6x-20x-15\\ \\ \ =2x(4x+3)-5(4x+3)=(4x+3)(2x-5)\\ \\ \frac{3}{4x+3} +\frac{21}{8x^2-14x-15}=\frac{3}{4x+3} +\frac{21}{(4x+3)(2x-5)}\\ \\ =\frac{3(2x-5)+21}{(4x+3)(2x-5)}\\ \\ =\frac{6x-15+21}{(4x+3)(2x-5)} \\ \\ =\frac{6x+6}{(4x+3)(2x-5)} \\$

The water level in a pool is currently at 1/2 of an inch. Every hour, the water level increases 4.75 inches. How many hours will

____ [38]

Answer:

7.1 hours

Step-by-step explanation:

Given data

Let the number of hours taken to fill the pool be x

the current quantity is 1/2 the capacity of the pool

we are given that the rate of flow = 4.75 in per hour

let the total amount of water after x hours be y, the expression for the quantity of water is given as

$y= 0.5+4.75x$

if y= 33.75 in, let us find x

$33.75= 0.5+4.75x\\\\33.75-0.5= 4.75x\\\\33.25= 4.75x\\\\$

divide both sides by 4.75

$x= 33.75/4.75\\\\x= 7.10$

Hence, it will take 7.1 hours

She needs 3/4 cup of water she needs 10 more servings what's the answer A 1/1/5 b 3/1/4 c 7/2/4 d 8/2/3

Eddi Din [679]

<h2><u>Corect option</u> :</h2>

$= \color{plum}\tt(C) 7 \frac{2}{4}$

<h2><u>Answer with steps</u> :</h2>

Quantity of water she needs $= \tt \frac{3}{4} \: cup$

Number of servings she needs = 10

Number of cups of water she will need :

$= \tt \frac{3}{4} \: \times 10$

$= \tt\frac{30}{4}$

$=\tt 7\frac{2}{4} \: cups$

Thus, she needs $\tt 7\frac{2}{4} \: cups$ of water.

Therefore, the correct option is $\color{plum}\tt(C) 7 \frac{2}{4}$
