The sum of 12 and a number
(12 + n)

is no greater
< =

then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)

so we have :
(12 + n) < = (2n - 8)

The rational expressionwrite this ratio in the form p(x) + x/(x - 2) Where is some x - 2

loris [4]

Answer:

$\frac{2x^2+5x-14}{x-2}=(2x+9)+\frac{4}{x-2}$

Step-by-step explanation:

Given rational expression is,

$\frac{2x^2+5x-14}{x-2}$

x - 2) 2x² + 5x - 14(2x + 9

2x² - 4x

9x - 14

9x - 18

Therefore, $\frac{2x^2+5x-14}{x-2}=(2x+9)+\frac{4}{x-2}$ is the answer.

You are creating an emergency fund and decide to place $415.00/month in an account that earns a 3.75 APR. How much interest accr

hoa [83]

At the end of the first full month the interest acquires is $ 1.30.

Step-by-step explanation:

Since we are looking for the interest for full month, we have to divide the APR by 12.

Because APR is the interest amount for the full year.

So 3.75 % = 3.75/100 = 0.0375

Now multiplying, we will get

415 × 0.0375/12 = $ 1.30

The price of a cycle is reduced by 25 per cent. The new price is reduced by a further 20 per cent.Find the single reduction the

Evgen [1.6K]

Answer:

40% . The single reduction together is 40%.

Step-by-step explanation:

Let the bicycle cost is x before reduced price.

First 25% is reduced and again 20% further reduced.

Let the single reduction is y% if the two reduction together are equal.

Solution,

Case .1

reduction cost $=x\times 25%$ %

$=x\times 25/100$

$=x/4$

The cost of bicycle after reduction of 25% is

$=x-x/4=3x/4$

cost of reduction further reduction of 20% $=3x/4\times 20$ %

$=3x\times 20/(4\times 100)$

$=3x/20$

The new cost of bicycle is further reduction of 20% is

$=3x/4-3x/20$

$=\left ( 15x-3x \right )/20$

$=12x/20=3x/5$

Case.2

if single reduction is done new cost of cycle is equal

$x-x\times y$ %= $3x/5$

$x\left ( 1-y/100 \right )=3x/5$

$\left ( 100-y \right )/100=3/5$

$100-y=60$

$y=40$ %

single reduction of a cycle is 40%
