Write each fraction as the sum or difference of two terms.

Elden [556K]

Solution:

16.

Given: 3n+5/7

We can rewrite it as:

3n+5/7 = 3n/7 + 5/7

The sum of two terms is 3n/7 + 5/7.

17.

Given: 9p-6/3

We can rewrite it as:

9p-6/3 = 9p/3 - 6/3

= 3p - 2

The difference of two terms is 3n/7 + 5/7.

18.

Given: Length = -2n+17

Width = 24

Area = length * Width

= (-2n + 17) * 24

= -48n + 408

Hence, the simplest form is -48n + 408.

From a sample of 9,750 Ajax trucks, 273 developed transmission problems within the first two years of operation. What is the pro

-Dominant- [34]

Answer:

0.028

Step-by-step explanation:

Let sample space, S, be the trucks.

Hence, n(S)= number of trucks=9750

Let E be the event of the truck failing within the first two years of operation.

Hence, n(E)=273

Therefore by classical definition of probability, the probability of occurrence of the event E, denoted by P(E), is

P(E)= $\frac{n(E)}{n(S)}$ = $\frac{number of trucks failed within two years of operation}{Total number of trucks}$

⇒P(E)= $\frac{273}{9750}$ =0.028

A rectangle with an area of 3990 cm2 is x centimeters wide and (x+4) centimeters long. To the nearest tenth of a centimeter, the

Karolina [17]

Answer: width:60.2 cm

Length: 64.2 cm

Step-by-step explanation:

Given

The area of the rectangle is $3990\ cm^2$

Width of the rectangle is $x\ cm$

Length of the rectangle is $x+4\ cm$

Area of the rectangle is the product of length and width

$\therefore 3990=(x+4)x\\\Rightarrow 3990=x^2+4x\\\Rightarrow x^2+4x-3990=0\\\Rightarrow x=60.198\ or\ -65.198\ cm\\\text{Neglecting negative term}\\\Rightarrow x=60.198\approx 60.2\ cm$

Width of the rectangle is $60.2\ cm$

Length of the rectangle is $60.2+4=64.2\ cm$
