First, here's a neat trick if you hate dealing with fractions (I just learned this today XD) Find the LCM of the denominators which in this case is 8 then multiply 8/1 by the fractions.
8/1(-5/4c-1/4=-3/4+5/8c)
You would end up with: -10c - 2 = 6 + 5c
Now do -10c - 5c to get -15c
-15c - 2 = 6
-2+2 cancels
2+6=7
-15c=7 divide each side by 15
The answer is c = -7/15

The answer is -8/15 because you need to cancel out the variables first

Simplify this rational expression. 2x^2+5x+3/2x^2-x-3

Murljashka [212]

Answer:

$2x+3$ / $2x-3$

Step-by-step explanation:

firstly we make two steps to simplify this question.

1st step: simplify $2x^{2} +5x+3$

to simplify this we use factorization

$2x^{2} +2x+3x+3$

$2x(x+1) +3(x+1)$

$(2x+3) (x+1)$ .....(1)

2nd step:simplify $2x^{2} -x-3$

$2x^{2} +2x-3x-3$

$2x(x+1)-3(x+1)$

$(2x-3)(x+1)$ .....(2)

now dividing (1) and (2), we get the answer

$2x+3/2x-3$

One city's highest temperature during this passed summer was 34 degrees Celsius, a second city's highest temperature over

PtichkaEL [24]

Answer:

$\°F = 93.2$

City 2 has a higher temperature

Step-by-step explanation:

Given

$\°F = (\°C * 9/5) + 32$

$City\ 2 = 97\°F$

Required

Convert 34°C to °F

Substitute 34 for C in the above formula:

$\°F = (34 * 9/5) + 32$

$\°F = 61.2 + 32$

$\°F = 93.2$

<em>Comparing 93.2 to City 2's temperature of 97; we can conclude that city 2 has a higher temperature</em>
